201106032 六、發明說明: 【發明戶斤屬之技術領域3 相關申請案之交互引述 本申請案主張於2009年7月7日提出申請之第61/ 223,628號美國暫准專利申請案的優先權,全部揭露内容就 所有目的在此完整地併入本案以為參考資料。 發明領域 本發明係有關於超高多工分析系統及方法。 C先前技術3 發明背景 在分析系統中,增加一既定系統在任一時間所進行的 分析數目之能力,係增加該系統的功用與延長使用期限之 一關鍵部份。尤其,藉由增加一既定系統之分析的多工因 子,可增加該系統的總處理量,藉而增加其效用及同時減 少該項用途的相關成本。 在光學分析中,多工之增加通常造成困難度之增加, 因其可能需要更加複雜的光學系統、增加照明或偵測能力 及新的反應圍阻策略。在一些情況下,系統係尋求增加數 倍及甚至級數規模之多工,其使得該等考量更加複雜。同 樣地,在特定情況下,待使用該系統的分析環境具高度敏 感性,藉此可能不容許一既定系統的不同分析之間之變 異。該等目標通常與單純地使該系統更大及具更高功率之 蠻力方式相衝突,因該等步驟通常產生甚至更嚴重的後 果,如反應之間的串擾、因訊號較低與雜訊較高中之任一 201106032 或二者所產生的訊號雜訊比降低等。因此,在其等所欲的 分析上提供具有顯著增加的多工之分析系統將為有利的, 及特別是在高度敏感的反應分析上,及在許多情況下,同 時將增加多工的負面效應降至最低。本發明符合該等需求 與多種其他需求。 【發明内容】 發明概要 本發明提供用於分析基板上的反應區域之非常高多工 分析之方法、基板及系統,及特別是用於進行高度敏感、 產生低訊號的反應諸如單分子螢光分析之多工系統,如單 分子即時核酸定序技術中所用者。 就一方面而言,本發明係用於製造包含一微鏡陣列的

發明之詳細說明 I.多工分析系統 多工光學分析系統係用於廣泛種類的不同應用中。該 等應用可包括單分子之分析,及可涉及例如在單一生物分 子進行反應之際之即時觀測。為了討論之方便,在此係就 一較佳應用:核酸序列資訊之分析及特別是單分子核酸序 列分析,論述該等多工系統。雖然就一特定應用敘述,應 瞭解本發明的系統之應用係指較廣泛的應用。 就單分子核酸定序分析之内涵而言,觀測一種單一固 定化核酸合成複合物,其包含一種聚合酶酵素、試圖闡明 其序列之一模板核酸及與該模板序列的一部份互補之一引 子序列,以在其等被納入延長的引子序列之際辨識個別的 核苷酸。典型地在其納入作用之前、期間或之後,藉由觀 測該核苷酸上之一種光學上可偵測的標記,而監控納入作 用。在一些情況下,該單分子分析使用一種“一次一鹼基方 式”,藉此一次引入一種單一類型的帶標記核苷酸及與該複 合物接觸。在納入之際,自該複合物洗除未被納入的核苷 酸,及以作為該固定化複合物的一部份之形式偵測被納入 的帶標記核苷酸。 18 201106032 在一些實例中,在^貞測納入作用時,僅添加一種單一 類型的核苷酸。該等方法需要循環經歷各種不同類型的核 苷酸(如A、T、G與C),方可測定模板的序列。因為在任一 時間僅一種單一類型核苷酸與該複合物接觸,就定義而 言,任一納入事件即為所接觸的核苷酸之納入作用。該等 方法雖然有一些效用,通常當模板序列包括多個重複核苷 酸時面臨困難,因可納入與單一納入事件不可區分之多個 鹼基。在一些情況下,對於該議題所提出的解決方法包括 調整所存在的核苷酸濃度,以確保單一納入事件係動力學 上有利的。 在其他情況下,同時添加多種類型的核苷酸,但藉由 在各類型核苷酸上所存在的不同光學標記而可區分。因 此,該等方法可使用一種單一步驟辨識序列中的一特定鹼 基。尤其,在固定化複合物中添加各帶有一種可區分的標 記之所有四種核苷酸。然後審查該複合物,以辨識納入何 種類型的鹼基,及依此方式辨識模板序列中的下一個鹼基。 在一些情況下,該等方法一次僅監控一種鹼基的添加 作用,及因此其等(及在一些情況下之單一核苷酸接觸方法) 需要附加的控制,以避免在任一特定步驟中添加多個鹼基 及因此被偵測系統漏失。典型地,該等方法在該核苷酸上 使用終止子基,以在一旦納入一核苦酸後阻止引子的進一 步延長作用。典型地可移除該等終止子基,以在一個經偵 測的納入事件後容許受控的再延長作用。同樣地,為避免 與先前所納入的核苷酸之標記混淆,典型地將該等核苷酸 19 201106032 上的標記基設計為可移除的,或在其他情況下可去活化的。 在另一種方法中,即時監控單分子引子延長反應,以 辨識在延長作用產物中之核苷酸持續納入作用,以闡明標 的模板序列。在單分子即時(或SMRTtm)定序作用中,當發 生時’即監控在一種聚合酶媒介式模板依賴型引子延長反 應中之核苷酸納入過程。就較佳方面而言,在一光侷限區 域内諸如-種零模式波導或鄰近—透明基板、光學波導等 的表面,提供典型為g]統之模板/聚合㈣子複合物(如見 第6,917,726號與第7,17〇,〇5〇號美國專利及第細7_〇134128

C Prior Art 3 Background of the Invention In an analysis system, the ability to increase the number of analyses performed by a given system at any one time is a critical part of increasing the utility and extending the life of the system. In particular, by increasing the multiplex factor of an analysis of a given system, the total throughput of the system can be increased, thereby increasing its utility and at the same time reducing the associated costs of the use. In optical analysis, an increase in multiplexing often results in an increase in difficulty as it may require more complex optical systems, increased illumination or detection capabilities, and new reaction containment strategies. In some cases, the system seeks to increase the number of times and even the scale of the multiplex, which makes such considerations more complicated. Similarly, in certain situations, the analytical environment in which the system is to be used is highly sensitive, which may not allow for variations between different analyses of a given system. These goals often conflict with brute force methods that simply make the system larger and more powerful, as these steps often have even more serious consequences, such as crosstalk between reactions, low signal and noise The signal-to-noise ratio generated by any of the higher-level 201106032 or both is reduced. Therefore, it would be advantageous to provide an analytical system with significantly increased multiplex on its desired analysis, and in particular in highly sensitive reaction analysis, and in many cases, at the same time, will increase the negative effects of multiplexing. Minimized. The present invention meets these needs and a variety of other needs.

Multiplex Analysis System The multiplex optical analysis system is used in a wide variety of different applications. Such applications may include single molecule analysis and may involve, for example, immediate observation at the time of a single biomolecule reaction. For the convenience of discussion, a preferred application is here: analysis of nucleic acid sequence information and, in particular, single-molecule nucleic acid sequence analysis, to discuss such multiplex systems. Although described in terms of a particular application, it should be understood that the application of the system of the present invention refers to a broader range of applications. For the connotation of single-molecule nucleic acid sequencing analysis, a single immobilized nucleic acid synthesis complex comprising a polymerase enzyme, a template nucleic acid attempting to elucidate one of its sequences, and a primer complementary to a portion of the template sequence is observed. Sequences to identify individual nucleotides as they are included in the extended primer sequence. Inclusion is typically monitored by observing an optically detectable label on the nucleotide before, during or after its incorporation. In some cases, the single molecule assay uses a "primary one base format" whereby a single type of labeled nucleotide is introduced at a time and contacted with the complex. Upon inclusion, the complex is washed from the unincorporated nucleotide and the labeled nucleotide is included as part of the immobilized complex. 18 201106032 In some instances, only one single type of nucleotide was added when the effect was included. These methods require cycling through a variety of different types of nucleotides (e.g., A, T, G, and C) to determine the sequence of the template. Since only a single type of nucleotide is contacted with the complex at any one time, by definition, any inclusion event is the incorporation of the contacted nucleotide. While these methods have some utility, it is often difficult to include multiple repeat nucleosides in a template sequence, as multiple bases that are indistinguishable from a single inclusion event can be included. In some cases, the proposed solution to this topic involves adjusting the concentration of nucleotides present to ensure that the single inclusion event is kinetically beneficial. In other cases, multiple types of nucleotides are added simultaneously, but are distinguishable by the different optical labels present on each type of nucleotide. Thus, the methods can identify a particular base in the sequence using a single step. In particular, all four nucleotides each having a distinguishable label are added to the immobilized complex. The complex is then examined to identify which type of base is included, and to identify the next base in the template sequence in this manner. In some cases, these methods only monitor the addition of one base at a time, and therefore their (and in some cases single nucleotide contact methods) require additional control to avoid adding more in any particular step. The bases are therefore missing by the detection system. Typically, such methods use a terminator on the nucleotide to prevent further prolongation of the primer upon incorporation of the mononucleic acid. The terminator groups are typically removable to allow for controlled re-prolongation after a detected inclusion event. Likewise, to avoid confusion with previously incorporated nucleotide labels, the labeling groups on such nucleotides 19 201106032 are typically designed to be removable or otherwise deactivated. In another approach, a single molecule primer is monitored in real time to elongate the reaction to identify the continued incorporation of nucleotides in the prolonged product to elucidate the target template sequence. In the single molecule immediate (or SMRTtm) sequencing action, the nucleotide incorporation process in a polymerase-mediated template-dependent primer extension reaction is monitored when it occurs. In a preferred aspect, a surface of a template/polymeric (tetra) sub-composite, typically in the form of a zero-mode waveguide or adjacent-transparent substrate, optical waveguide, etc., is provided in a region of the optical confinement (see, for example, 6,917,726).

US2007/003570號與第US2007/003804號國際專利申請案, 全部揭露内容就所有目的在此完整地併入本案以為參考資 料)。藉由使用多個光束,或在線性化之前或之後將單_光 束分光,如藉由讓該光束通過一繞射光柵,可產生數個平 行的照明線如照明線210,以照明一基板上之多列的共、線反 應區域。該標定照明作用藉由未照明介於照明線之間之基 板空間而減少照明作用的浪費,及因而減少與先前所論及 的過量照明相關聯之許多議題。然而,仍照明介於共線反 應區域之間的空間,如在一特定列内,而產生浪費照明作 用與雜訊增加之伴生議題。 在進一步的改良中,如第2D圖所示’標定照明廟型使 用各照明一子集或一個單一離散式反應區域之陣列式照明 點,如照明點212。藉由僅照明需要照明的空間,如位於該 反應區域及/或附近,其進一步增強訊號雜訊比,及増加照 23 201106032 明效率而優於線性照明廓型。可使用數種光學構形,以產 生該等類型的標定照明廓型,包括如使用將個別的照明光 束聚焦成為多個陣列式照明點之透鏡陣列、首先將—個單 一光束分光成為一列的多個光束及然後將該等光束中之各 者分光成為一正交定向列的附加光束之正交定向型繞射光 柵、將一個單一光束轉換成為包括如一基板上之照明點的 網格陣列之多種不同的標定照明廓型中之任一者之繞射光 學元件(如見於2008年5月9日提出申請之第12/ 15丨,979號美 國專利申請案及PCT/US2008/05953,其中各者就所有目的 在此完整地併入本案以為參考資料)。 該系統選擇性地在光學元件串内附加包括共焦或空間 濾波器’以進一步限制在該系統的焦平面之外如與反應區 域無關聯者之反射光或所發出的螢光之影響。 第3圖說明該系統之一實例。如所示,系統30〇包括一 反應陣列諸如一種零模式波導陣列302,在其上排有數個離 散式反應區域之陣列。在零模式波導陣列之情況下,典型 地在基板上提供列與行的陣列之大量零模式波導。在不同 的ZMW内提供用於一特定分析之所欲探討的反應物。例 如,就藉由合成作用之核酸定序的内涵而言,與ZMW—起 提供包括一模板核酸序列、一互補引子序列、一核酸聚合 酶酵素及引子延長作用所需之核苷酸或核苷酸類似物的_ 反應混合物之一定序複合物(如見第1圖)。可以超高密度矣且 合ZMW陣列’提供自每平方公分1000個ZMW至每平方公分 1,000,000個ZMW或更多。因此,在任一時間,分析在單— 24 201106032 分析系統内或甚至在一個單基板上之自100、1000、3000、 5000、10,000、20,000、50,000、1〇〇,〇〇〇或 1百萬、1千萬或 更多個ZMW或其他反應區域中所發生的反應,可為適合需 要的。 如所示,該系統包括用於激發反應區域中的螢光反應 物之一激發輻射源’諸如雷射304。一光學元件串306將來 自雷射304的激發輻射輸送至ZMW陣列或基板302。該光學 元件串亦收集來自陣列上的不同ZMW之螢光訊號,及將該 等訊號傳送至一偵測器,諸如EMCCD330。該光學元件串 306包括一多工組件,諸如繞射光學元件(d〇E)308(亦稱作 全像光學元件或HOE),其將一個單一激發光束轉換為大量 的個別激發光束,該等個別激發光束將標定對應陣列上的 ZMW302位置之照明點的一陣列。該多個光束係選擇讓激 發光通過及反射來自陣列302的螢光之分色鏡316。在通過 分色鏡316之前,照明光束可通過可能與一對聚焦透鏡如透 鏡310與314配套之一共焦濾光鏡312,以將該等光束聚焦通 過該共焦針孔。通過分色鏡316的激發光,然後經由物鏡318 而以一標定模式聚焦在陣列302的平面上。 然後藉由物鏡318收集來自陣列302的螢光訊號,及傳 送至分色鏡316,分色鏡316則將螢光訊號反射朝向偵測器 330。來自陣列上的離散式ZMW之訊號然後通過一空間濾 光鏡諸如共焦光罩322,以減少出自焦平面自發螢光或散射 光之背景雜訊諸如光致發光,共焦光罩322典型地又與一對 聚焦透鏡如透鏡320與324配套。該等訊號然後通過以差別 25 201106032 方式引導光譜雜*同的光之—分散性光學元件諸如模形 棱鏡326’以容許基於偵測器上的入射位置而區別不同的螢 光汛说。經差別方式引導的訊號成分然後朝向通過附加的 聚焦光學兀件,如聚焦透鏡328,及最後撞擊該EMCCD偵 測器330。如所示’―特定訊號在偵測器上的入射位置係指 示⑴該陣列中的發端ZMW,及(2)該訊號成分的光譜特性, 其係用於辨識例如在—延長反應巾所納人之帶螢光標記核 苷酸類似物的類型。 已述及使用上述系統之同時標定照明一陣列中的數千 或數萬個ZMW之作用1而,隨著對於多工需求之增加, 增加-陣列上的ZMW密纽提供料陣列祕定照明作 用之能力之困難度,亦隨著因較高的密集照明水平等而起 UMW串擾(來自鄰近ZMW的訊號當自該陣列出射時彼此 污染)、訊號雜訊比減少等議題而增加。 II.多工方式 雖然上述的系統適用於提供有欵的多工光學系統,若 能藉由納人特定的系統改良而進—步增加該料統的多工 能力,將為適合需要的。 本發明提供用於監控基板上之數量較多的陣列式複合 物之方法、系統及組件。舉例而言,於細年5月9日提出 申凊之第12/151,979说美國專利申請案及pCT/US2〇〇8/ 05953(先前在此併人本案)述及分析大量的陣列式反應區域 如核酸定序複合物之方法,其錢^丨導標賴明點至離 散式反應㈣及收集來自_纽應區域的鮮訊號之多 26 201106032 工光學元件。如所示,該等系統選擇性地亦包括共焦光罩, 以增強來自該偵測作用的訊號雜訊比。本發明的系統係用 於經由多種途徑而進一步增強全系統的多工。 因此,雖然本發明的系統可用於提供一基板上的10 個、100個、1000個、5000個等的離散式反應區域之多工分 析,在特佳方面本發明將用於提供超過5000個離散式反應 區域、超過10,000個離散式反應區域、超過20,000個離散式 反應區域、超過50,000個離散式反應區域及甚至超過 100,000個離散式反應區域及至多1,〇〇〇,〇〇〇個或更多個離 散式反應區域之多工分析。除了藉由本發明的系統可分析 之反應區域的剪切數量之外,將理解在一些情況下,經由 本發明所提供的各項優點,該等反應區域的配置密度可高 於先前所用者。例如,可提供與觀測高密度的離散式反應 區域而無過度的干擾或其他問題性議題。該密度例如可為 每平方公分 1000個、10,000個、100,000個、1,000,000個、 10,000,000個或更多個反應區域。觀測體積的密度可增加至 所用觀測光之繞射極限,就該等應用中所預期的一些波長 而言,其可低至250奈米。在該種間隔,在一正方陣列中可 顯現每平方公分至多16e9觀測體積,而在六方密集陣列中 稍微更多。經由使用近場光學元件可超越該繞射極限,導 致其限制僅由該侷限的實際尺寸所決定,其尺寸可小至5〇 奈米。在一正方陣列中間隔100奈米,導致密度為每平方公 分lelO 。 此外’就所監控之該數量的區域而言,該多工分析係 27 201106032 實質上同時。 “實質上同時’’係指在1至5個(較佳1至2個)照相影格的 時段内,分析所需數目的區域。就本發明的系統之目的而 言,典型地自約每1毫秒至約每10毫秒捕捉一照相影格(或 影格速率自約100Hz至約1000Hz) ’藉此為歸於一實質上同 時的分析之範圍内’該等多工區域之分析應在自約1毫秒至 約10毫秒之時間範圍内發生。結果,提供所欲的多工分析 之一系統,如在自1毫秒至約10毫秒的窗口内觀測多個位置 至少各一次者,將稱為實質上同時,即使該分析係在該窗 口内的二個不同時間點進行。 在一些情況下,可使用較慢的影格速率,其將增加二 事件可發生的時間階段’及在此之際自照相機的觀點而言 似乎仍為實質上同時。可使用例如10Hz至100Hz、10Hz至 5〇Hz、10Hz至20Hz的影格速率,如約15Hz。將理解,發生 在毫秒範圍如自1毫秒至約500毫秒、1〇毫秒至約1〇〇毫秒等 之取樣速率,可視為實質上同時。 A.增效型光學元件 在基板上的離散式反應區域之分析中實質增加多工之 能力,面臨數項限制。舉例而言,在監控來自單分子反應 的榮光訊號之系統中,集光光學元件典型地使用具有相對 小的視野之高數值孔徑物鏡。因此,增加的多工典型地需 要較密集的反應區域,以使料__物鏡㈣來自數量較多 的該等區域之訊號。然而’一基板上之較密集的反應區域 產生系列之附加的解析度議題,例如包括區域之間的串 28 201106032 擾等。 第4圖說明光學串擾。如所示,在一基板上提供基板402 上的反應區域(如404、410及412)之一陣列,諸如零模式波 導404。對於發生在該等區域中之以螢光方式監控的反應進 行照明,及發出與該反應相關聯之螢光訊號。如來自相鄰 反應區域410與412之實線箭頭406與虛線箭頭408分別所 示’該訊號的全向發射廓型造成來自相鄰區域的訊號彼此 干擾之可能性’尤其當該等區域在基板上變得更加密集 時。該“串擾作用”限制將反應區域密集以供分析之能力。 依據本發明的特定方面,使用強化光學方式以增強訊 號收集之效率。 該光學方式中之一者提供添加聚焦光學元件,以用於 將反應區域之間的光學申擾降至最低,及在許多應用中亦 容許使用具有較大視野的物鏡。藉由減少串擾的可能性, 可增進將反應區域密集之能力。同時,藉由改採用視野較 高的物鏡,可將配置該等區域的面積擴大。除了降低串擾 之外’本發明的聚焦光學元件亦可藉由將光改向進入一摘 測器,增加所偵測到的光量,其係在未改向的其他情況下 該偵測器所無法偵測者。藉由將光改向,可使用例如所收 集的光量與未改向情況相同但具有較低的數值孔徑之一偵 測系統,以容許例如較大的視野。就本發明中所預期的方 法之内涵而言,具有大的視野可為重要的,例如就容許— 次同時觀測數萬個發光或發螢光區域而言。任擇地’藉由 引導該光,可使用相同的數值孔徑而收集更多的光。如更 29 201106032 詳細地敘述於後,本發明的聚焦光學元件藉由引導照明光 進入一陣列諸如一種零模式波導陣列上的一反應區域中, 亦可增加照射水平。 微鏡陣列 就一方面而言,本發明係提供定形微鏡的一陣列,其 中各微鏡係與一光偈限相關聯,及特別是被納入包含該光 侷限的同一基板之定形微鏡的一陣列。 第5A圖說明如本發明之一定形微鏡陣列的一實例。如 所示,全基板502包括配置於其表面上之一反應區域陣列, 諸如零模式波導504-514。圓錐形或拋物面鏡516_526係集成 進入下方的透明基板52 8,及其構形係將入射光改向至陣列 中的ZMW ’或將來自陣列中的ZMW之射出光聚焦。尤其, 該圓錐形或拋物面鏡典型地由一反射材料諸如一金屬層如 鋁、銀、金、鉻等組成,及製入下方基板以提供該鏡表面。 如第5B圖所示,藉由一鏡諸如一拋物面或圓錐形鏡, 將自ZMW内之反應所發出的螢光訊號53〇改向或聚焦,以 増加該等訊號的收集效率。如在此所示,例如將進入該基 板上的反應區域之全向發出的光改向,藉此使其更容易地 被谓測到。在一些情況下,如在此所說明者,至少可將該 光部份地準直。此外,就各反應區域或ZMW而言,該鏡構 ^减少或消除在基板本身内之ZMw之間的串擾。除了減少 争擾之外,將理解因將所發出的光改向或聚焦而增強的收 隹 >、攻率,亦增加該系統的靈敏度。同樣地,該定形的光學 几件亦用於將入射的照明作用如光532聚焦在反應區域諸 30 201106032 如 ZMW504-514 上。 對於納入該等圓錐形鏡之裝置言,亦可採用任擇的構 形。例如,一個零模式波導的核心區域可延伸進入下方的 基板中。該實例係說明於第5C圖中,其中反應區域55〇延伸 超過覆蓋層552及進入下方的基板554中,在一也情況下容 許將鏡556所反射的訊號更有效地傳至與傳出反應區域 550。在總構造内可附加地包括選擇性的組件諸如阻光區域 或渡光鏡組件’包括例如光罩558,以進一步增強該鏡系統 的光學性質。 雖然在此所述的鏡係稱作“圓錐形,,或“拋物面,,鏡,將 瞭解該集成反射性聚焦光學元件組件之特徵在於其等在基 板内提供一反射組件之能力,其藉由將自反應區域發出而 通過基板的光改向而增強光的偵測作用,不計其確切的形 狀為何。在一些情況下,至少將自反應區域發出的光部份 地準直。本發明之定形鏡因而將來自基板上的一光侷限之 光,改向至一偵測器或至一光學元件,該光學元件係將光 自基板引至一偵測器之光學元件串的一部份。聚焦鏡可包 括拋物面構造以外的形狀,諸如圓錐形鏡構形、分段式圓 錐形鏡構形、截圓錐形鏡構形、部份拋物面鏡構形、梯式 鏡構开>、角錐形鏡構形等,前提在於該等構造將光改向, 例如藉由部份準直作用而增強自反應區域發射的光或通過 反應區域進入基板的光之偵測作用。在許多情況下,該等 鏡將具有圓柱對稱。鏡的形狀可為一種擬柱體,例如一種 角錐、楔形、稜鏡、反稜柱、鐘狀或其截頭體。當該鏡具 31 201106032 有多個側面時,諸如當其包含一角錐或一角錐的截頭體 時’該鏡可具有適且的側面數量。例如,當該鏡包令__角 錐時’該角錐可具有3、4、5'6、7、8、9、1〇、1卜12個 或更多個側面。 本發明的定形鏡通常為微鏡,意指該等鏡為小型的, 通常具有數微米或數十微米的尺寸。在一些情況下,亦使 用微反射器一詞指稱一微鏡。該等鏡所具有的戴面尺寸可 自約0.1微米至約100微米、約1微米至約5〇微米或約2微米 至約20微米。雖然本發明的鏡之尺寸為數微米至數十微 米,在些情况下本發明的疋形鏡可較大,例如自約1 〇〇微 米至約1毫米或更大。 此外,雖然依在基板本身内提供一反射材料諸如一金 屬層而說明,將理解可同樣地採用其他反射構形而不使用 一金屬層。例如,該等構造可由不同折射率的材料所組成, 以提供所表現的功能與在本案他處所述的金屬層相同之一 反射介面。例如,自具-折射率的—區域行進通過一介面 而進入具-較低折射率的一區域之光,若該光的入射角超 過一既定數值(臨界角)’通常將完全地内反射。依此方式, 藉由適當地調整該形狀任-側面之材料的折射率,毋;使 用一反射層,即可產生本發明的反射構造。 在-些情況下,本發明的定形反射構造包含圓錐平反 射器。在理論模式與實驗上,均顯示_形反射器型式中 的效率顯著優於非反射㈣基板。在—些情況下,圓錐步 構造係有㈣,因其等可容㈣藉由多種方法形成。例如: 32 201106032 可藉由控制光阻的幾何形狀及藉由微影條件,而控制壁的 錐度。例如藉由控制光阻的聚焦/曝光條件以控制該光阻的 拓撲,或藉由灰階微影法,可控制該光阻的幾何形狀。亦 可藉由控制#刻條件’例如控制表面鈍化作用的量或藉由 灰I5白触刻作用而控制形狀。本發明的圓錐形鏡基板通常 包含-種截圓錐構造。該圓錐形鏡基板的截圓錐區之壁可 為直的’或可包括-些彎曲。第6圖說明三種圓錐形構造之 實例。第6A圖顯示-圓錐形鏡構造,其中該鏡的構造係包 含一個直筒圓錐形構造6 〇 〇之一截圓錐,其係配置於一反應 區域或反應區下方的基板層中,諸如零模式波導63〇,以將 進入或離開該反應區域的光改向。第6B圖顯示具有一個下 圓錐區604與一個上圓錐區606之一種分段式圓錐形構造。 在β亥構造上配置一個反應區域640 〇在該實施例中,下圓雜 區604的側壁具有相對於基板法線之第一角度,及上圓錐區 606的側壁具有相對於基板法線之第二角度,其中第二角度 大於第一角度。在一些情況下,上部區的壁所具有之相對 於法線的一角度將小於下部區。如第6C圖所示,該圓錐形 構造可具有一個下截圓錐區608及其壁垂直於基板之—個 上圓柱區610。在該構造上配置一個反應區域650。具有第 6C圖的廓型之構造可適用於產生高密度的陣列。例如,具 有一圓柱頂部與/圓錐形下部之一構造,其所具有的基本 尺寸通常將小於具有相同側壁角度的單截圓錐構造。在一 些情況下,若該構造的基本尺寸較小,在一特定區域内所 置入的構造將更多。第6圖所示的反射構造係以自一底部透 33 201106032 明層突出之方式顯示。該底部透明層可為一平面基板,諸 如在其上表面上具有突出構造之一熔融矽石晶圓。第6圖之 構造通常將具有與該構造的壁相鄰之一反射塗層或一反射 區域,以增強光的内反射作用。例如可藉由以一反射層塗 覆該突出構造,藉由以反射性材料填充突出構造之間的區 域,或藉由在突出構造外使用一種折射率較低的介質以激 勵内反射作用,而提供該定形基板的反射性表面。 雖然第6圖的圖解係指反應區域係位於圓錐形構造頂 部的中央,在一些情況下,反應區域可能並非位於正中央。 製造公差可能造成反應區域偏離中央位置。此外,在一些 情況下,例如為領受較高的照明水平,或例如當照明或偵 測光學元件係以偏離該特定反應區域的法線之一角度配置 時,可生產偏離中央的反應區域。 可以如上述用於ZMW陣列之高密度,組合微鏡陣列。 與反應區域配套的微鏡密度例如可為自每平方公分1000個 ZMW至每平方公分1,000,000個ZMW或更高。在任一時間, 使用此述的微鏡陣列,分析在單一分析系統内或甚至在一 個單基板上之自 100、1000、3000、5000、10,000、20,000、 50,000、100,000個或1百萬個、1千萬個或更多個214\^或其 他反應區域發生之反應,可為適合需要的。 第7圖顯示用於本發明的微鏡之一圓錐形構造。如第7 圖所示之截圓錐構造,構成在透明基板上延伸之一突出構 造。該截圓錐可為一圓柱對稱,具有一個直徑為A之實質上 圓形的頂面、一個直徑為C之實質上圓形的底部及半高直徑 34 201106032 為D。該截圓錐的高度為B。該載圓錐的壁為實質上平直 的,及相對於表面的法線具有—角度e。在此所示之載圓錐 構造的側壁為實質上平直的,但該等壁可為非平直及仍作 用於將此述的光強度改向。在一些情況下,用於產生該圓 錐形構造之方法,將產生自平直至例如具有f曲廟型不等 的羞在其他情況下,納入非平直的壁,以增進收集效率。 在許多情況下,用於產生該突出構造之方法,將造成具有 突出、***之表面,或在偏離平直廓型的側壁上之其他缺 陷。在—些情況下,對於增加—基板上的反舰域密度而 言,具有一平直廓型係適合需要的。例如,一彎曲壁諸如 -抛物面所具有的底部直徑可能大於—平直側面圓錐。藉 由使用底部直徑較小的構造,在一些情況下可達成較高的 密集密度。 具有第7圖所示廓型之本發明的例示性圓錐形構造,其 頂部直徑A係介於約(U微米與1〇微米之間,例如介於1微米 與20微米之間,或介於2微米與1〇微米之間。在一些情況 下,截圓錐的頂部直徑A係介於約丨微米與約5微米之間。在 一些情況下,該直徑係介於2微米與4微米之間。本發明的 例不性圓錐形構造所具有的側壁角度θ係介於約2。與4 $。之 間、介於約5。與35。之間、介於約1〇。與3〇。之間或介於約μ。 至約26。之間。所產生的圓錐形構造,係將例如位於圓錐形 冓的頂。[5中央之反應區域所發出的光改向。例示性構造 至少將反應區域所發出的光改向進入距該法線的角度約為 22.5之圓錐形構造。在本發明的例示性實施例_,圓錐形 35 201106032 構造的高度B係介於約0.2微米與約100微米之間、介於約工 微米與約10微米之間,或約2微米至約8微米或約3微米至約 6微米。在-些情況下,控制截圓錐高度相對於底部直徑之 比例(B/C)係適合需要的。在例示性實施例中,B:c的比例 係介於約1:3與約3:1之間’係介於約1:2與約2:1之間、介於 約1.5:1至約1:1.5之間或介於約h2:1至約1:12之間。該等技 藝從業人士將瞭解A、Θ及B之選擇將決定底部寬度(:> 如上 述,為了增加本發明的光學構造之密度,控制該等參數藉 此底部寬度C係小至足以容許所增加的密度,可為適合需要 的。底部直徑C可介於約0.2微米與約〗〇〇微米之間、介於約 1微米與約10微米之間,或約2微米至約8微米或約3微米至 約6微米。 本發明之一例示性圓錐形構造的頂部直徑A係介於約工 微米至約5微米之間,高度B係介於約2微米至約8微米之 間’及側壁角度係介於約10。至約3〇。之間。本發明的例示 性圓錐形構造將具有置於圓錐頂部部份之—反應區域, 通常約位㈣料央部份。該反應區躺如可I種零模 式波導,其包含配置通過該圓錐形構造頂面上的反射性覆 蓋層之一孔徑。該孔徑所具有的直徑可為約3〇奈米至約3〇〇 奈米。 第8 (A)與8 (B )圖顯示本發明之定形鏡的二種例示性構 造。例如藉由發展用於包括+導體製程的微製造及用於產 生MEMS裝置諸如料納人光㈣法與㈣作用者之方 法’可產生該等構造。第8(A)圖顯示一透明基板8〇〇,在其 36

些情況下’反應區域840將延伸進入透明基板中。在微鏡的 外側壁上配置一反射層830,以增強該等壁的反射性。在一 些情況下,覆蓋820與反射層830將為相同的材料,如鋁。 透明表面上方的區域810可含有包含試樣及/或反應物之— 液態介質’其可擴散進出該反應區域。在一些情況下,陣 列中的所有反應區域將與區域810中的相同溶液接觸。在— 些情況下’將在反應區域之間包括障壁,以降低或阻止反

以增加光阻的靈敏度。依適當及如技藝中所教導者,可進 行光阻之移除及基板之淨化、沖洗、灰化與乾燥。 在一些情況下,用於反應區域(如ZMW)之光微影工 具,係使用可產生形體尺寸約1〇奈米至約1〇〇奈米的構造之 光微影曝光工具。該系統例如包括AMSL XT1250曝光工具。 在本發明的一些方面使用蝕刻方法’以在透明基板中 或在其他層中產生三維形體,以構成例如光學元件諸如微 鏡或透鏡,或反應體積諸如奈米級孔徑。所用的蝕刻方法 將依所用的材料類型、形體尺寸及光阻系統而定。在一些 情況下,使用濕式#刻作用或濕式化學勉刻作用。亦可使 用電化學蝕刻作用。在一些實施例中’使用電漿蝕刻作用 或反應性離子蚀刻(RIE)作用作為餘刻方法。例如當所欲者 係具有高的高寬比之構造時’亦可使用深反應性離子触刻 53 201106032 作用(DRIE)。亦可使用例如以二氟化氙進行之乾式蒸氣相 名虫刻作用。當適於產生本發明的構造時,可使用體型微加 工作用或面型微加工作用。用於本發明的方法中之蝕刻作 用,可為灰階蝕刻作用。控制光阻形成作用與蝕刻作用之 條件,以產生具有所欲的幾何形狀之側壁諸如具有所欲的 側壁角度,以作用為微鏡。 本發明的一些方法涉及反射層或覆蓋層之澱積作用。 可藉由濕式方法包括自溶液旋塗在層上,或藉由氣相方 法,而完成該等反射層的澱積作用。適宜的方法包括電鍍 作用、濺鍍澱積作用、物理氣相澱積作用、蒸發作用、分 子束磊晶法、原子層澱積作用及化學蒸氣澱積作用。可使 用金屬作為反射層與覆蓋層。適宜的金屬包括金、鎳、鋁、 鉻、鈦、鉑及銀。反射及/或覆蓋層可包含鋁,其可藉由濺 鑛作用而澱積,例如使用可自CVC、諾發(Novellus)或MRC 公司取得之一種商品化濺鍍工具。 當在本發明的方法期間澱積各層時’在一些情況下, 該等層在移至方法中的下一步驟之前進行處理。例如,所 澱積的層可進行退火、平面化、淨化、鈍化或輕度蝕刻, 以增進其性質。 在本發明的一些方法中’澱積保護層或犧牲層。保護 層可為聚合層,或可為無機層。適宜的保護層或犧牲層包 括鍺(Ge)與非晶矽(a-Si)。保護層可用於產生此述的形體。 可就其選擇性反應性,例如對於濕式化學蝕刻劑的選擇性 反應性,選擇用於保護層或犧牲層之材料類型。例如,在 54 201106032 一 it况下,在一氧化矽與鋁存在下,以加熱的過氧化氫 l擇丨生地似彳鍺之能力,造成其被用於製造與奈米級孔徑 配套之光學微鏡構造。 在-些方法中,使用一種拉開方法。拉開方法通常涉 及自層内之-形體邊緣關,以減少該形體的尺寸。可 使用選擇性地與具有暴露邊緣的—層反應之 一種濕式化學 減劑’進雜開作用。在__些情況下,係使用過氧化氣拉 開一鍺層。 —些方法使用一拋光步驟,以自基板移除一表面區 域。適宜的方法包括化學機械拋光作用或化學機械平坦化 作用(CMP)。 本發明的一些方法納入一平坦化層。用於澱積平坦化 層之方法將依所用的材料類型而定。平坦化層可為一種硬 質材料,諸如一種無機材料例如氮化矽;其可為一金屬材 料諸如紹;或其可為一軟質材料,諸如一種聚合材料如一 種有機或矽式聚合物。平坦化層可為玻璃,諸如一種二氧 化矽材料。在一些情況下,平坦化層包含一種旋塗式玻璃 諸如一種矽酸鹽、磷矽酸鹽或矽氧烷材料。適宜的旋塗式 玻璃材料例如可自漢威(Honeyewell Corporation)公司取 得。平坦化層可包含例如摻雜其他作用劑以控制其熔融性 質之一種玻璃,諸如硼-磷-矽酸鹽玻璃(BPSG)。適宜的聚 合性平坦化材料例如包括聚醯亞胺。 可將本發明的陣列納入分析系統中,以用於分析發生 在該陣列的反應區域中之多個反應。此述的陣列典型地具 55 201106032 有來自頂部的流體可到達之反應區域,及其為來自底部的 光學分析可到達。因此通常將該陣列納入一容器中,及在 該容器中引入所欲探討之一反應混合物。在一些情況下, 個別的反應區域皆與一體積的流體接觸,該流體可具有例 如可進行分析之多個核酸模板分子,及其可具有核苷酸、 輔因子及用於進行待分析的反應之其他添加劑。 包含該陣列之容器可置於具有適當的光學組件、電腦 控制及資料分析系統之一儀器内。包含該陣列之容器將被 固定於該儀器内,藉此可控制反應條件諸如容器溫度與容 器的大氣條件。容器的大氣條件可包括試樣上方的氣體組 成,例如濕度及其他氣體物種諸如氧之水平。 集成透鏡陣列 如同集成拋物面鏡,可使用多種習用技術製造透鏡陣 列,包括例如半導體製造方法、聚合材料的微模製等。例 如,如同用於上述集成鏡之製造方法的部份,諸如反應性 離子蝕刻作用之蝕刻方法可用於製造該等透鏡陣列。任擇 地,如上所提及,可變的離子佈植方法可用於改變基板組 件的折射率,而以一現有基板界定透鏡。如亦將理解者, 亦可在基板中製造對於來自反應區域的光提供增強的集光 作用之附加光學元件。例如,上述的離子佈植方法,可用 於界定直接用於基板中之各個不同反應區域之繞射光柵。 在任擇方面,以將傳至及/或來自基板的螢光訊號至少 部份準直或聚焦之透鏡陣列,置換(或在一些情況下擴增) 該圓錐形或拋物面鏡。第21圖說明該種透鏡陣列。如所示, 56 201106032 總裝置2100再度包括配置在一透明基板2116的第一表面 2114上之一陣列的零模式波導,如ZMW2102-2112,及所欲 探討的反應在其中進行。微米或奈米透鏡如透鏡2118-2128 之一陣列,係配置於透明基板2116的對向(或後)表面2134 上。如所示,該等透鏡具有同一尺寸,及其係以與ZMW陣 列配合之一節距配置,藉此各ZMW具有其本身的配套透 鏡。如同第5B圖的鏡陣列,將自ZMW發出的光改向,例如 藉由與其配套的透鏡部份準直,及收集與分析該光以監控 所欲探討的反應。雖然該等透鏡在消除基板内的串擾方面 不如拋物面鏡構造有效,其等提供成本與容易製造之附加 的效益,及在一些情況下可用於取代或輔助該等集成鏡。 如所示,透鏡陣列可集成進入下方的透明基板。任擇 地,透鏡陣列可分別地製造及與下方的基板接合,以提供 相同或類似的結果。雖然以配置在陣列的後表面之一種單 層透鏡說明,將理解該透鏡陣列可由各定址基板上的不同 區域之多個透鏡層所組成,或在基板上的—肢區域組合 以提供-所欲的光學功紐。另外,雖然以自透明基板的 後表面突出之透鏡說明,在-些情況下,透鏡可在透明基 板内集成。例如,透鏡可在適#位置組裝進入下方之基板, 藉由提供在該等位置的基板之折射率變化。如制的透鏡 製造’可使用微加玉技術將個別透鏡嵌人基板中,以提供 雙折射率。料,藉由在基板的藝部份產生—折射率梯 度,基板的該等部份可作用為透鏡。可藉由數種方式,例 如包括離子佈植方法,改變基板例如—種玻璃基板的折射 57 201106032 率。除了透鏡或透鏡陣列之外,可同樣地將繞射光柵或其 他光學功能性組裝進入下方的基板中。 因為藉由聚焦光學元件將來自基板的訊號至少部份準 直,對於乍視野、高數值孔徑物鏡之需求減少,而可使用 較廣視野、較低NA物鏡,其通常賦予全系統成本與可用性 之優點’因可使用製造較不嚴密的物鏡。此外,用於製造 較高倍物鏡的異類材料當暴露於激發輻射時,可引起物鏡 本身的光致發光之增加。 此外’因為使用較低倍物鏡,在物鏡與基板之間所提 供的間隔,可大於當使用高數值孔徑物鏡時所通常提供 者°該附加的間隔容許在基板與集光物鏡之間***附加光 學組件’如適當的分色鏡。在至少一個例示性實施例中’ 在基板與物鏡之間提供之一分色鏡,容許將來自集光物鏡 及其他集光光學元件組件的照明光分開。藉由進一步將激 發路徑與偵測路徑分開,及尤其藉由提供並未看見激發光 之一集光物鏡’可完全消除集光路徑中因激發照明通過該 物鏡所引起之自發螢光或光致發光。該光學裝置之一圖解 係示於第22A圖。如所示,全系統2200包括在其上配置數個 反應區域2204之一基板2202。亦以集成進入該基板(如所示) 或以個別組件之形式,包括例如用於將來自反應區域的光 學訊號準直及/或將照明作用聚焦在反應區域上之聚焦光 學元件(如上述的集成微鏡或透鏡)。該系統亦包括一激發光 源2206或多個激發光源,以提供激發光至基板22〇2。激發 光係經由位於集光物鏡2210與基板2202之間之分色鏡2208 58 201106032 而導向基板。藉由將來自集光物鏡2210的激發光分開,可 避免與集光物鏡2210的自發螢光相關聯之問題,自發 可為引起雜訊的重要原因之一。 在措由分色鏡2208反射至基板2202之前’激發照日月^乍 用典型地亦將經歷附加的操作,諸如分光、波束整形、淚、 波等。例如,激發光可通過多工光學元件,如繞射光學元 件(DOE)2212,以提供大量的個別的小射束;以及通過用於 將小射束聚焦在基板的焦平面上之聚焦光學元件,如物鏡 2214 〇 所發出的訊號憑藉其等來自激發光之不同光譜特性, 通過分色鏡2208及藉由集光物鏡2210收集。如先前所示, 當業已藉由聚焦光學元件將來自基板的訊號部份準直時, 集光物鏡可具有顯著較低的倍數,如自用於無聚焦光學元 件的一系統之視野3毫米以下的一種60X(數值孔徑為〇 9)或 更高倍物鏡,改為視野45毫米以上的一個4X(數值孔徑為 0.28)或更低倍物鏡,而仍提供足以用於單分子分析之靈敏 度。如同第2圖所示之系統,所收集的訊號然後例如可藉由 通過稜鏡2216而進行光譜分離作用,及例如經由透鏡η” 而進一步聚焦,或在偵測器222〇進行偵測之前進行其他操 作。 基板的分色鏡與照明路徑之一附加或任擇的圖解,係 示於第22B圖。如所示,分色鏡層22〇8係夾在二個稜鏡225〇 與2252之間的介面。來自一照明源如雷射22〇6之激發輻 射,係導向分色鏡2208。如所示,激發輻射首先被基板22〇2 59 201106032 的後表面反射’如實線箭頭所示。激發光然後被分色鏡2208 反射朝向基板及配置於其上的反應區域,如第22A圖中的反 應區域2204。自反應區域所發射的螢光訊號然後可通過分 色鏡2208進入物鏡2210,及進入光學元件串的剩餘部份及 偵測系統’如第22A圖中所示。藉由如第22B圖中所示以垂 直於光程之一定向提供總分色鏡元件,而非如第22A圖中所 示之相對於該定向之傾斜,可減少引入該物鏡空間的光學 像差量,而光學像差視情況可能降低在偵測平面或共焦平 面之影像品質。 B.時間多工 就一方面而言,可經由一既定系統的時間多工,如在 不同時間暴露不同的區域,以辅助或取代此述的其他增加 多工之方案,而達成多工之增加。該系統可包括以相對低 速在不同的區域組之間切換,其係類似於一種掃描方式, 如在不同的時間在不同區域照明及/或偵測,其中對於不同 區域而言,不同的時序較不具關鍵性。任擇地,及參照本 發明的部份’分析之時間多工係以就一特定分析而言之充 分頻率進订,在不同的區域實質上同時進行·作用及/或 偵測作用,藉此自照相影格擷取速率之方面而言,在不同 區域的偵測作驗乎是同時,如先前所說明者。 本發明的该方面係以圖式方式說明於第23圖中。如所 不,在一基板2300上提供第一照明模式,其係在第一時間 點如時間t-o照明反應區域231〇的第一子集23〇2。然後在時 間t-卜將&定的照賴式切換至照明區域23觸—個不同 60 201106032 t=〇與t=1在時間上係充分 子集2304。就本發明之目的而言 接近,如切換頻率係充分的,藉此該二照明模式係實質上 同時的’如崎彙在杨域所歧者。雖颜顯示者係 在㈣與之間⑽的二财集模式,將轉如本發明之多 種不同的照明模式可在所欲的時段内照明與切換,以提供 不同區域之實質上同時的照明作用。例如,可以實質上同 時之方式分別地照明區塊、縱列、部份或區域之隨機或任 意的選擇或子集。 在至少-實施中,本發明的時間多工系統使用一種光 千切換組件’其可選擇性與快速地在二或多個不同的光路 控之間切換’而照明基板上的不同區域。例如,在第一方 面 为析系統的照明路徑包括位於光程内之一種可切換 式定向鏡,以將激發照明的方向切換至基板上的不同位 置。在更複雜的系統中,可使用可快速地將標定照明作用 導向一基板的不同部份之一種可程式鏡陣列,諸如一種數 位光學處理器(DLp)。如可選擇性地切斷子集或甚至個別小 射束的光程之其他動態切換組件,例如包括MEms快門陣 列、空間光調變器諸如LCDSLM。第24圖說明該種照明路 控之一實例。如所示,照明路徑2400包括一激發輻射源, 诸如雷射2402。s亥雷射係導向通過適當的多工光學元件, 諸如一或多個繞射光學元件、光柵等,如DOE2404,以產 生所欲多工之一標定照明模式。該標定照明模式係導向一 鏡2406 ’其選擇性地將部份的照明模式引導通過剩餘的光 學元件串,諸如分色鏡2410與物鏡2408,以入射在基板2414 61 201106032 上之5玄區域的一部份上。該鏡的快速切換造成在不同時間 對於基板2414上的不同區域之高頻率照明作用,但較佳位 於該偵測系統的影格擷取期間内。在特佳彳面,該切換系 統的運作頻率係超過該系統中的—器之入射速率,如照 相機的影格擷取速率。尤其,在H影格擷取事件中 切換至少1次,及較佳至少2次,及在—些情況下例如更常 切換至少3次、4次、5次或更多次’在照相機獲取一個單一 影格的時間内,該切換過程應為該偵測系統基本上無法偵 測與不可觀測的。舉例而言,對於影格速率如自1〇〇至 1000Hz之種尚速照相機而言,偵測系統的切換頻率應至 少為100Hz、200Hz、ι000Ηζ、2〇〇〇Hz或甚至更高。如將理 解者,在一些情況下,個別的小射束動態調制作用可用於 調整個別小射束或小射束子集之相對強度,以針對因光學 系統中的其他像差如漸暈等所引起之跨基板的變化進行調 整。 如將理解者,雖然述及以間歇方式傳送多工光學元件 2404之多工光束的不同部份至基板2414,在一些情況下, 切換組件可能單單地將多工光束改向至基板2414的不同部 伤,以進一步增強多工。例如,在一些情況下,多工光學 元件2404可產生照明第一區域子集之一照明模式,如第23 圖中之子集2302。切換功能然後引導相同模式的標定照明 作用至一附加的區域子集,如第23圖中之區域2304。因此, 可選擇性地設計該多工光學元件以提供相同功能,諸如照 明每隔一縱列或排的反應區域。然後設計該切換光學元件 62 201106032 諸士鏡2406之構形,以在一半的期間將光束改向照明居間 縱列或排的反應區域。 C.搜尋活性 雖然本發明的許多方面係朝向增加經歷分析反應用的 照明及/或偵測作用之反應區域的總數目,在—些情況下, 可經由初始審查大量的反應區域,接著僅對於具活性如顯 示所欲探討反應的跡象之該等區域的一子集進行後續照明 及/或偵測作用,而達成一有效的多工。因此,在又一方面, 增加的多工僅施用在一基板上之活性區域。實際上,該方 法審查大置的反應區域,但僅繼續分析一小型子集。因此, 雖然對於一高多工進行有效地初始審查,最終的分析係在 可能甚至不需要一超高多工因子之顯著較小的反應區域子 集上進行。所得的分析有效地增加多工,亦即相關區域的 分析處理量之水平較高,同時不需在整個分析期間維持高 多工分析。結果,所需的能量輸入可能比直接的高多工方 式低,同時具有在訊號雜訊比等方面之增益。第25圖以圖 式方式說明前所提及的方法之概觀。如所示,首先廣泛地 審查具有大量的潛在反應區域之2502—基板2500,以辨識 活性反應區域(如實心圓25〇4所示)。該廣泛照明作用可為統 一泛光照明整個基板或其顯著部份之形式,或可為對於不 同區域的掃描分析之形式,以辨識該等展現活性者。任擇 地,可類似地使用標定照明方式,以辨識活性區域2504。 一旦辨識出,然後配置光學系統而僅照明該等展現活性的 區域,造成僅照明及因此監控來自該等區域的訊號(如虚線 63 201106032 圓2506所示)。 該選擇性照明作料㈣多種不同的光學系統或組 件例如’如同上述的時間多工照明方法,可快速地配置 可程式鏡陣列’而僅照明_特定基板上所選擇的確切區 域。同樣地’如習用的平面LCD顯示器中所用之具有可定 址晝素的LCD光罩,可用於選擇性地照日卜基板上的所欲 區域。該等組件可如有關第24圖中之鏡2楊所述地配置, 以選擇性地崎定向前往基_賴性區域之小射束。尤 其’藉由提供—種LCD式光罩,可選擇性地定址個別畫素, 使其等對於激發照明如小射束的透射作㈣啟或封閉,因 而控制最後入射在基板上之小射束的數目與模式。 除了在基板上的不同區域提供可控制式光罩照明作 用之外,上述方式亦可用於調節一基板上的不同區域之照 明強度。尤其,藉由調制通過不同光罩元件的光,可調制 基板所接收的光強度。上述的調制作用特別適用於因應其 他光學組件所造成的標定照明作用中之不均—性,如多工 光學元件如DOE等中的變化所造成之不均一性。尤其,可 製造一灰階光罩,或在可程式空間光調變器之情況下進行 程式化,以調整在不同照明區域之標定照明作用之間之任 一預定的不均/性。尤其,可獲得一特定光程的照明廓型 之一取樣品,包括多工光學元件,及基於該模式配置空間 光5周變器或光罩,以適當地修正偏差,如減少較亮的照明 點之強度。 D.增強型多工照明作用 64 201106032 在其他方面,本發明使用與一或多個繞射元件組合的 多個照明源而提供增強型多工照明作用,以照明大量的離 散反應區域。在該等情況下,可將二、三、四、五、十或 更多個雷射光束引導通過一或多個繞射光學元件,以在一 基板上產生大量的照明點。 在例如使用一繞射光學元件提供離散光束而照明一基 板上的大量離散區域時,為確保將充分的電力輸送至大量 的照明區域,典型地需要增加施用至該系統的電力。就超 高多工系統而言,用於進行此之個別照明源因為成本與可 用性,在商業上並非可行。例如,在特定的例示性應用中, 係將單一照明源光束分成提供約5微瓦/平方微米之小射 束。若要對於80,000個離散點達到該相同的照射功率,則 表示單一照明光束將具有約500百萬瓦。 除了雷射議題之外,繞射光學元件典型所產生的光束 模式在相對小的視野具有合理的光束均一性。然而,當希 望擴張視野時,該照明模式的非均一性對於一些應用而言 將過量。因此,在多工照明規模例如擴張一級數或更多時, 將預期跨照明點的照明強度之顯著變化。 因此,就一方面而言,本發明提供導向通過一或多個 繞射元件的多個照明源及/或來源光束,以提供具有容易取 得、低功率照明源及較高的跨照明視野均一性之超高多工 照明作用。 在第一方面,將多個照明光束以不同角度引導通過單 一繞射元件,以提供反射多個光束的輸出照明模式及發端 65 201106032 光束中的角度變化。其係以圖式方式說明於第26圖中。如 所示,實線2602與虛線26〇4所示之多個照明光束,係以如 角度2608所示的不同角度導向繞射光學元件26〇6。自各發 端光束的DOE所發射之照明“小射束”2610所產生的模式, 係以其本身的模式(如以基板2612上的 貫心與空心點而圖 式說明)導向基板2612上,其中各模式係以該二發端光束之 間的角度差異之一函數方式偏位。 除了使用多個照明源光束之外,本發明亦設想使用多 個繞射元件,其中各繞射元件接收發端照明光束的一子 集’以產生-關聯模式。;,因&自單—繞射元件所發 射的較高多工模式在整個較大的視野所提供之變異可能過 量’可使用各在-特定基板的-區域子集提供__照明模式 之多個繞射元件,藉此將㈣仙變祕關在相對小的 視野中所存在者’及因此不超過用於所欲應用之範圍。 該種系統的一實例係說明於第27A圖中。尤其,如所 示,提供-種多工繞射光學元件27〇6,討包含一種單一 集成組件或多個連接型繞射光學元件27()4。多個發端昭明 光束(如發射自多個照明源如雷射_之實線、短虛線及長 虛線所示)係導向多工DOE2706,其中各光束係以自其他光 束稍微偏移的-角度導向DOE。如所示,可包括—個多面 體稜鏡、波導陣列、光纖束或其他光學組件,以將各光束 改向至其適當的廳組件。此外,陣列中的各咖組件可 在角度方面偏斜,以提供所發射的小射束通過剩餘的光學 元件串之最佳方向。 66 201106032 自集成DOE2706内的各DOE元件2704所產生之光束模 式,然後透射通過將光束聚焦在一基板2714上之光學元件 串(如透鏡2708、2710及物鏡2712所示)。如所示,將不同的 光束χΚ焦’以將其荨的照明模式提供至該基板的不同子 集。例如’如该光束的示意展開圖所示,來自各組件2704 的照明模式之交錯可用於提供多重偏位,但係與基板2714 上的照明模式交錯,如第26圖所示之模式。任擇地,不同 的小射束模式可導向基板上之完全不同的區域如象限等’ 以照明個別的基板區域。 第27Β圖說明用於達到高多工之數種d〇e組件構形,包 括五DOE陣列組件(a)與(d)、七〇〇£陣列組件(b)與(e)及九 DOE陣列組件(c)與⑴。依多工水平與所欲的照明模式而 定,亦可用其他構形。就較佳方面而言,除了在角度空間 中將各入射光束均勻地分成照明模式中之大量的小射束之 外,一陣列中的各DOE組件將被配置具有不同的偏斜角 展。例如’就第27B圖中所說明的九面式DOE組件而言,陣 列中之各個別的DOE組件或面可提供來自一個單一入射光 束之100x100的小射束。其等可具有均一的間距如在㊀乂與 ey角度空間皆為〇.1毫弧度(mrad)。第一DOE(#1)的偏斜角 展例如在㊀乂方向為5毫弧度,第二DOE(#2)將在θχ與㊀丫角 度空間皆偏斜5毫弧度,第三DOE(#3)將在0y角度空間偏斜 5毫弧度等等。 如將理解者及如上所提及者,各D〇E可用於將—或多 個照明光束轉換成為導向基板之小射束模式。 67 201106032 E.多工偵測作用 類似於施用於此述分析系統的照明側之多工方式,及 輔助或作為該等方式的一替代方案,本發明亦在該系統的 收集側提供增強的多工,如用於收集與偵測自—基板上之 反應區域所發射的訊號之光程。尤其,對於超高多工系統 潛力之至少一項限制,係彳貞測例如自一基板上之較大型與 較大量的離散區域所發射訊號之能力。如將理解者,在任 一時間對於來自一基板上之不同區域的訊號偵測之預期的 實際限制,將受限於一特定偵測系統中之晝素或偵測器元 件的數目。 尤其,一特定的偵測器像素將僅可偵測入射在其上的 號’及在其他考量不存在下’對於來自一來源的訊號與 來自另一來源或組合來源的訊號將無法辨別。然而如將瞭 解者’每個像素具一訊號之實際限制在於其本身並非完全 可行’因多個像素上的訊號偵測作用提供大量的不同資 訊,諸如光譜資訊、陣列位置等(如見第2007-0206187號美 國專利申請公開案、第W02007/095119號國際專利申請公 開案及於2008年6月5日提出申請之第12/134,186號美國專 利申請案,其中各者之全部揭露内容就所有目的在此完整 地併入本案以為參考資料)。類似地,將陣列上的訊號成分 分離係有助於避免訊號交叉污染。鑑於該等與其他考量之 結果,在多工方式中,偵測器陣列區域的有效率使用之最 佳化,將為有利的。 在第一實例中,自一基板上的反應區域之一陣列所發 68 201106032 射的訊號,可導向一偵測器陣列或甚至完全不同的偵測器 陣列上之不同區域,以最佳地偵測來自高多工基板的訊 號。在一相關實例中,來自個別訊號來源的不同訊號成分 可導向不同的偵測器。 任擇地或附加地,正如同照明的時間切換作用,自一 基板的不同區域所發射之訊號可在時間上分隔,但在其他 情況下在不同的時間導向一基板之相同、重疊、相鄰或離 散部份。再次,藉由以超過及較佳顯著超過最慢的訊號期 間之一頻率施用該切換作用,該時間分隔作用將提供對於 所欲訊號事件之無縫偵測作用。此外,藉由將訊號分析過 程與切換作用同步化,可容易地將基板上的一特定位置指 定予一訊號事件,甚至當該等訊號係入射在一偵測器陣列 的相同位置上時。如將理解者,相同或類似的組件可用於 訊號方向的光學切換作用,如在標定照明模式的切換作用 部份所論及者。此外,將理解先前所論及的LCD光罩可同 樣地用於集光路徑,以針對來自離散式反應區域或反應區 域子集之訊號,選擇性地開啟與關閉該集光路徑。 藉由“工作分擔”偵測器在不同訊號來源之間的偵測區 域,雖然在不同的時間點,可使得以單一偵測器或一組偵 測器偵測的訊號來源數目倍增超過未使用時間多工之一方 法。 在一相關方面及如上所提及者,可將包含大量離散式 反應區域之一個別基板,分成多個不同的子視野(sub-FOV),其中各者可導向一個不同的偵測器,以順應高多工 69 201106032 基板。為有效率與同時地監控該等子視野,較佳保有達成 該監控方法之單一光學元件串。因此,就一方面而言,本 發明提供照明一基板上的數個反應區域之一光學系統,但 將來自反應區域的多個子集中之各者之訊號導向不同的偵 測器。 用於收集來自一基板的不同區域之螢光訊號及將其等 傳送至不同偵測器之一光學系統之一實例,係以圖式方式 說明於第28圖中。如所示’系統2800包括一基板2802,其 具有位於其上或其内的數個離散式反應區域或所欲探討的 區域。基板2802及特別是用於分析之區域,係配置於物鏡 2804的前焦平面。如所示’物鏡2804與筒鏡2806將所欲探 討區域成像在位於筒鏡2806的後焦平面及靠近反射光罩 2808之一中間影像平面。反射光罩2808將影像分割,及將 —子集反射朝向偵測器2810及一部份朝向偵測器2812。典 型地在焦平面中提供該反射光罩的反射點,藉此不會造成 保真度之損失。另外顯示該等偵測路徑中之各者包括光譜 分離光學元件,分別如聚焦透鏡2814與2816及2818與 2820,以及用於分色的分散性光學元件,分別諸如稜鏡2822 與2824。雖然係以將影像分成二個分開偵測的影像之形式 說明’將理解可配置反射光罩或其他分像光學元件,以將 影像分成更多的影像組份,如2、3、4、8、16或更多個離 散的影像組份,其中各者可導向一個不同的偵測器。 如先前所提及,可以數種方式完成分像作用。例如, 在簡單方面’反射光罩2808可包含如一種具有分開的偏斜 70 201106032 =之風輪式鏡,其中各面在—個不同的偵測路徑反射一 一的〜像。任擇地,使用微稜鏡或微鏡陣列,如作為反 =先罩28G8’以將各子視野的影像導向不同的偵測路徑, 其具有以-所欲方向y導入射光之多面體表面的陣列。如 將理解者’可如本發明配置該科列,以將影像分成數個 離散的組成影像。 在-相關系統中’可將來自基板上之不同訊號來源的 不同訊號成分’區別地導向不同的制器。尤其,在如第 22圖中所示之n㈣祕中,如藉由分散性光學元件 2216將多個訊號成分在空間上分離,及成像在偵測器2220 上。就超高多工陣列基板而言,當不同的訊號來源緊密地 配置在該陣列上時,在空間上分離不同訊號成分的影像之 能力變得更加困難,因並無足夠的偵測器區域供容納分離 的成分’及其等開始映射至 貞測器陣列的實質上重疊部 伤。藉由將不同的訊號成分導向不同的彳貞測器,可將該基 板上之更密集的訊號來源成像。其係以圖式方式說明於第 29A圖。尤其,如示意影像2902所示,4個訊號成分如光譜 上獨特與分離的螢光訊號影像2904-2910,係成像在一债測 器陣列的一部份上。藉由將訊號成分的子集如訊號29〇4/ 2906與2908/2910區別地引導至不同的偵測器,可有效地成 像近乎二倍數目的訊號來源如ZMW,而不需擔心訊號重 疊。以該數目的偵測器如二個偵測器可成像的訊號來源之 數目’提供成像至多二倍訊號來源之能力。然而在較佳的 情況下,用於區別相鄰訊號來源所需之附加的間隔,可能 71 201106032 使得來自不同來源的訊號成分之間需具有較大的間隔。因 此,可成像的訊號來源之數目,可能並非完全地跟隨偵測 器數目。 在第29B圖中提供用於完成上述偵測多工之光學系統 的一圖式說明。在所示的系統中,該系統的激發光學元件 之設置係與第22圖所示的系統類似,如在物鏡與基板之間 具有一雙色渡光鏡。尤其,如所示,全系統2950包括一或 多個激發光源,諸如雷射2952與2954。如同所有的該等系 統,激發來源的數目可依據特定應用的需求而改變,如該 系統中所用的不同螢光團之激發波長、所用雷射之波長。 在所示的例示性系統中,藉由將二種激發光源(照明光源) 導向分色鏡2956而將其等組合於相同的光程中,分色鏡 2956透射來自雷射2954的光及反射來自雷射2952的光束, 藉此5亥一光束成為共線。再次,在所示的系統中,激發光 束係導向一附加的分色鏡2958,其作用係將激發光反射朝 向基板2960,同時將具有不同波長的螢光訊號傳送至集光 物鏡2962。如所示’該訊號首先自另一組件的表面反射, 如該光學元件串中的一個分開的鏡或該基板的後表面,如 上在第22圖中所述者。來自基板2960之光譜上分離的訊號 成分’如經螢光標記的不同試劑所發射者,然後通過分色 鏡2958與物鏡2962。然後藉由通過一分散性光學元件諸如 楔形稜鏡2964 ’將訊號成分分成光譜上分離的訊號成分(如 自稜鏡2964所發出的實線與虛線箭頭所示)。訊號成分然後 導向分色鏡2966 ’其反射訊號成分的—子集及透射另一組 72 201106032 訊號成分。然後將訊號成分的不同子集中之各者成像在偵 測器2968或2970上。如上所示,雖然顯示具有二個偵測器, 將理解可使用附加的偵測器,以將訊號成分的其他子集成 像,如經由使用附加的分色鏡而可具有各導向一個不同的 偵測器之四個訊號成分。 F.玻璃填充式物域 就一方面而言,本發明係提供具有一玻璃填充式光學 空間之改良型光學系統。如此述,用於分析例如具有分析 化學反應所用的螢光試劑之反應區域陣列之光學元件系 統,通常具有入射在反應區域上之照明光學元件,及偵測 發生在反應區域中之反應所發出的光之集光光學元件。在 一些情況下,可使用藉由作用為例如照明波長的光之一鏡 但傳送發射波長的光之一分色鏡元件,以控制照明作用與 集光系統的光程。在一些情況下,使用一種自立式分色鏡 可導致光學像差及損失。在本發明中納入一種定形光學區 塊,其在照明光學元件與試樣之間及在集光光學元件與試 樣之間的光學空間具有一嵌入式分色鏡元件。該光學元件 區塊所具有的折射率典型地將超過空氣的折射率。藉由具 有較高的折射率,所發出的光中之較大部分可藉由具一特 定進光孔徑的偵測光學元件收集。此外,藉由嵌在光學區 塊内的分色鏡,減少入射在該區塊上之光線的偏斜角度及 圓錐角度,而在一些情況下導致較佳的分色鏡光譜性能及 增加系統靈敏度。 包含一種定形光學元件區塊之一系統的一例示性實施 73 201106032 例係示於第30圖。照明(激發)光學元件3030將照明光邡衫 引導通過面3001而進入光學區塊3〇〇〇。在所示的實施例 中’在區域3070塗有一反射性材料以增強内反射作用之面 3002將照明光反射。該照明光然後自嵌入式分色鏡元件 3010反射,通過面3〇〇2而進入可包含多個反應區域之基板 3020 ’該反應區域所具有之反應可藉由偵測螢光事件而測 量。所發出的光3045,如來自反應區域的螢光,經由面如耵 進入該區塊,及透射通過分色鏡元件3〇1〇。在所示的實施 例中,基板3020係與光學區塊3000光耦合,以將反射損失 與像差降至最低。所發出的光然後經由面3〇〇3離開該定形 光學區塊,及進入集光光學元件3040。雖然第3〇圖顯示反 射照明光及透射所發出的光,在一些實施例中,嵌入气八 色鏡將透射照明光及反射所發出的光。 照明光與所收集的光透射通過之該定形光學元件區塊 的面可為平面,及可以最大化光學性能之一角度配 旦' 〇例 如,可將該等面製造為垂直於相關光學元件串的主光線 依此方式,就修正像差之目的而言,該定形區塊可作用為 一個厚、不傾斜的平板。在一些實施例中,該定形光學元 件區塊的一或多面可為彎曲的,以將通過該面的光改向而 提供透鏡功能。該等面可如所欲地以凹或凸方式弯曲,以 將照明光或所發出的光改向。 通常預期光學元件區塊將包含該系統的光程長度之大 部分。亦即,通過光學元件區塊之光程距離,將至少為照 明光學元件與基板之間或集光光學元件與基板之間的總光 74 201106032 私距離之5G/〇、至少60%、至少7Q%、至少8Q%、至少9〇%、 至少95%、至少98%、至少99%或更高。在—些情況下照 明光學元件、基板、絲光學元件或上述的任-組合,係 與具有折射率局於空氣的_材料之㈣光學元件區塊光輛 合。例如可使用其折射率與㈣光學區塊或另_組件緊密 配合之-流體、油絲合物,而使得㈣元件光耗合。 分色鏡7〇件係嵌入該定形光學元件區塊中,顯示該分 色鏡7L件係㈣區塊光學制,及在分色鏡元件與光學區 塊之間通常很少或全無_存在。在—些情況下,分色鏡 可模製或㈣進人該定形光學元件區塊巾。在其他情況 下刀色鏡元件可以例如流體、油或聚合材料而與該部份 的光學區塊耦合。 疋形光干7G件區塊係由在所欲探討的波長為透明之一 材料製成。該區塊例如可由玻璃質氧化物材料製成。气區 塊例如可包含二氧切。可納人添加劑以調整該 區塊的折射㈣其滅質。在-些情況下,魏塊在所欲 探討的波長具有介於約U與約5.G之間之折射率,可為商人 需要的。該折射率例如可為或介於約1.3與約25之門’=口 於約Μ與2.0之間。軸在—些情況下,高折射率_ = 要的’在-些情況下,折射率較高的材料將傾向於具 高的自«光水平。因此吾等已發現具有料 射率之材料,係特別適用的。該區塊在分析所用的 圍具有低的自發榮光水平,係通常所欲的。 乾 地將使用例如在約4。。奈米至約7。。奈米範固:可2典: 75 201106032 可使用紅外光與紫外光。照明光之波長通常不同於所發出 的光之波長。 III.實例 第1例:拋物面鏡基板 製造具有配置通過一金屬層的零模式波導之基板,該 金屬層係澱積在一玻璃基板中所界定的一拋物面形體上。 該等裝置係依據第10圖及隨同的說明所述之方法製造,除 了未進行後續的基板平坦化作用(步驟V-VII)之外。使用聚 焦離子光束(FIB蝕刻方法)’製造用於界定零模式波導核心 之通過金屬層的孔徑,以界定直徑約12〇奈米之一核心。第 31A圖顯示使用掃描式電子顯微法(SEM),自構造的金屬層 側成像之所得構造。可見位於該構造的中央頂部之開口形 式的零模式波導核心。 亦提供如不具有第31B圖所示之任一拋物面或其他反

的螢光訊號比習用ZMW高6倍,顯示全系統的集光效率之 增強。 第2例:圓錐形鏡基板之理論模擬 76 201106032 使用第3 2圖與第3 3圖所分別說明的各種組件模製構 造。例如,就第32圖所說明之平直的圓錐形構造而言,尺 寸設定如下:dl = 1.25微米;d2=5微米及h=4.69微米。該模 式假設用於收集自基板/反射器組件所發出的光之一物 鏡,具有〇·5的數值孔徑及相對於光軸的最高集光角度為 +/-20度,藉此提供自70至110度之相對於基板底面的集光角 度。基於第32圖所示之圓錐形模式,自圓錐反射出的光線 角度係自43.58度(0〇至1〇5.52度(0&)。 就第33圖所示之二種分段式圓錐形反射器而言,尺寸 设疋為.dl-1.25微米;d2=3微米;d3=5微米;hl = l微米; 及h2=3.69微米。在該情況下,反射器所反射與發出的光線 角度係介於82.3 7度(0tr)至116.06度(0br)之範圍。 就上述二種結構型式而言’使用數值孔徑為0 95之一 集光物鏡之物鏡的光子收集效率估計約為70%,相較於不 包括反射器組件之一基板如第31B圖所示之配置於—透明 基板層上的一種零模式波導之收集效率約為42%。該分析 預測因微鏡之納入而增進光學性能,但該分析實質上係一 種不包括繞射作用或波效應之光線追跡分析,及因而無法 提供所預期性能的完整相貌。亦已進行以向量式工具所進 行之分析,其確認來自本發明的微鏡構造之光學增進作用。 第3例:使用犧牲柱在微鏡構造上製造奈米級反應區域之陣列 藉由350°C的LPCVD,在熔融矽石上澱積一層500奈米 形式的多晶錯。使用一種248奈米步進機、科林(Lam)餘刻 機、寬度調整自300奈米至120-150奈米,在多晶鍺中蝕刻 77

第35圖顯示在其頂部具有一反應區域之單一微鏡構造。第 36圖顯示位於一微鏡構造頂部之一奈米級反應區域。 第4例:使用一犧牲鍺層與一硬膜層光罩製造奈米級反應區域 依序以一多晶鍺層與一硬質光罩層諸如二氧化矽或氮 化矽,塗覆一熔融矽石基板。使用光微影法以界定直徑 約380奈米的環形之—陣列,及蝕刻該硬質光罩以產生具有 ’’’勺略。玄4尺寸的硬質光罩盤。然後使用3〇%含水過氧化氫 之一控制式過度蝕刻作用,蝕刻該鍺層,以在硬質光罩盤 之下方產生直徑約2〇〇奈米的鍺柱狀物。可藉由調整條件與 材料而控制蝕刻速率。例如,當使用無摻雜型多晶鍺時, 3〇%含水過氧化氫在5〇t的蝕刻速率約為460奈米/分鐘;而 當使用摻雜型多晶鍺時,3〇%含水過氧化氫在室溫的蝕刻 速率約為200奈米/分鐘。在該表面上濺鍍厚度約1〇〇奈米的 鋁。使用加熱至約5〇。(:以上的含水過氧化氫,移除多晶鍺 柱。SEM顯微圖證實在熔融矽石上的一鋁膜中產生直徑 介於自200奈米至250奈米範圍之孔。 第5例:在一熔融矽石基板上所產生的圓錐形微鏡構造 第3 7圖顯示在一熔融矽石基板上所形成的例示性圓錐 78 201106032 形微鏡構造之掃描式電子顯微圖。測得第37(A)圖之圓錐形 構造的頂部直徑約為2·40微米’及底部直徑約為4.90微米。 測得第37(B)圖之圓錐形構造的頂部直徑約為1.68微米,及

the observed volume during the nanocapsule action produces a signal pulse 112 as indicated by one of the symmetry associated with the retention effect. Once incorporated, the machine number, such as the A-track Λ ' in Figure 1B, releases the label attached to the polyphosphate component of the labeled nucleoside 20 201106032 acid analog. When the next appropriate nucleotide analog, such as nucleotide 110, is contacted with the complex, it is also incorporated, resulting in one of the T traces of Figure 1B corresponding to signal 114. By monitoring the role of the base in the primary stock, as shown by the basic complementarity of the template sequence, a long sequence of information about the template can be obtained. Furthermore, in order to obtain, for example, the amount of sequence information desired for a wide range of applications for genetic sequencing in research and diagnostics, higher throughput systems are desirable. For example, to enhance the sequencing throughput of a system, multiple complexes are typically monitored, with each complex sequenced a different template sequence. Where the genome is sequenced or other large DNA components are sequenced, the templates will typically comprise overlapping fragments of the genomic DNA. By sequencing each fragment, a contiguous sequence can then be combined from the overlapping sequence data of the fragments. In a preferred aspect, an array of various composites is provided on a substrate. The arrayed composite may be provided in an optically or structurally confined configuration such as a zero mode waveguide, or the like may form a pattern pattern on a surface. Optionally, the elements can be randomly placed on a surface, but undergo a calibrated array illumination or detection function whereby only the complex within an array pattern of the surface is monitored. For the purposes of this discussion, both configurations are referred to herein as monitoring functions of array composites and the like. Overall Several different mechanisms have been used previously to achieve multiplex analysis and even simultaneous multiplex analysis of discrete reaction zones. Figure 2 illustrates several of these methods. For example, in a simple implementation, an array of discrete reaction regions is arranged to cover a large number of such discrete regions of a wide illumination beam as the so-called "flood" illumination. It is illustrated in Fig. 2A, in which the solid circle 204 refers to a reaction zone or other zone disposed on the substrate 202, which is intended to be monitored, and the dotted line 2〇6 illustrates the boundary of the illumination zone. As shown, the single illumination zone is applied indiscriminately to a large or possibly all discrete reaction zones. Depending on the density of the reaction zone on a particular substrate, the floodlighting may include the use of a conventional laser beam or, in some cases, a beam-expanding optical element, by illuminating a larger amount with a single integrated beam or spot The reaction area to provide the desired multiplex. Although illumination is widely provided on a wide range of substrates on which one of several reaction zones is disposed, floodlighting may have an inconsistent illumination intensity of the illuminated area. In particular, the illumination intensity at the center of a particular beam tends to be large and attenuated at the edges. Thus, different reaction zones are typically illuminated differently depending on where they are in the illumination spot. Moreover, because the entire substrate range corresponding to the point is illuminated, it may result in inefficient use of the applied radiation, such as wasting light in the non-reactive area of illumination, and thus applying more radiation than is necessary. Moreover, the floodlighting can exhibit adverse effects of excessive illumination, such as excessive power consumption, reflected light being reflected, spontaneous fluorescence of the substrate and other optical components of the system, heating, and the like. In other methods, as shown in Figure 2B, an illumination beam is scanned through a substrate to illuminate a plurality of reactive sites or regions on the substrate. In particular, as indicated by the arrows, a relatively small illumination spot 208 is repeatedly moved through the surface of substrate 202 to illuminate each reaction zone, such as zone 204, respectively. Typically, such scanning systems employ conventional scanning systems such as galvanometers, rotating mirrors 22 201106032 or rotating prisms to direct light beams through a substrate surface over time. Although this specialized system is particularly effective for static systems, such as the search for an end point of an analysis other than in the case of very slow reactions, it is not particularly suitable for monitoring the progress of the reaction over time. In particular, because the illumination beam only occasionally pats each location for a relatively short period of time, it is unable to instantly illuminate and monitor one of the reaction zones in which a relatively rapid reaction occurs. In other methods, a calibrated illumination profile is used to preferentially illuminate multiple reaction sites simultaneously. For example, as shown in FIG. 2C, in a calibrated illumination mode, an illumination beam is linearized to provide an illumination line that simultaneously illuminates a plurality of discrete collinear regions on a substrate (see, for example, US2007/ International Patent Application No. 003, 570, the entire disclosure of which is hereby incorporated by reference in its entirety in the entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire all By using a plurality of beams, or splitting a single beam before or after linearization, such as by passing the beam through a diffraction grating, a plurality of parallel illumination lines, such as illumination lines 210, can be generated to illuminate a substrate. Multiple columns of common-line reaction regions. This calibrated illumination reduces the waste of illumination by not illuminating the substrate space between the illumination lines, and thus reduces many of the issues associated with the excessive illumination previously discussed. However, the space between the collinear reaction areas, such as in a particular column, is still illuminated, creating an associated problem of wasted lighting and increased noise. In a further refinement, as shown in Figure 2D, the calibrated illumination pattern uses an array of illumination points, or an array of illumination points, such as illumination points 212, of a single discrete reaction region. By illuminating only the space that requires illumination, such as being located in and/or near the reaction zone, it further enhances the signal to noise ratio and is superior to the linear illumination profile in terms of efficiency. Several optical configurations can be used to produce the type of calibration illumination profile, including the use of a lens array that focuses individual illumination beams into multiple array illumination points, first splitting a single beam into a single column. Beams and then orthogonally directional diffraction gratings that split each of the beams into an orthogonally directed array of additional beams, converting a single beam into a grid array comprising illumination points such as a substrate A diffractive optical element of any of the different calibrated illumination profiles (see, for example, U.S. Patent Application Serial No. 12/15, filed on May 9, 2008, and PCT/US2008/05953, each of which This article is hereby incorporated by reference in its entirety for all purposes. The system selectively includes a confocal or spatial filter' within the string of optical elements to further limit the effects of reflected light or emitted fluorescent light outside of the focal plane of the system, such as those unrelated to the reaction area. Figure 3 illustrates an example of this system. As shown, system 30A includes a reaction array such as a zero mode waveguide array 302 having an array of discrete reactive regions disposed thereon. In the case of a zero mode waveguide array, a large number of zero mode waveguides are typically provided on the substrate in an array of columns and rows. The reactants to be explored for a particular analysis are provided in different ZMWs. For example, in combination with ZMW, a nucleotide or nucleoside required to include a template nucleic acid sequence, a complementary primer sequence, a nucleic acid polymerase, and a primer extension is provided in combination with ZMW. A sequence-complex of the _ reaction mixture of the acid analog (see Figure 1). The ultra-high density and ZMW array can be supplied from 1000 ZMW per square centimeter to 1,000,000 ZMW per square centimeter or more. Therefore, at any one time, the analysis is from 100, 1000, 3000, 5000, 10,000, 20,000, 50,000, 1 〇〇, 〇〇〇 or 1 million in a single 24 201106032 analytical system or even on a single substrate. The reaction occurring in 1 million or more ZMW or other reaction zones may be suitable as needed. As shown, the system includes an excitation radiation source such as laser 304 for exciting one of the fluorescent reactants in the reaction zone. An array of optical elements 306 is delivered to the ZMW array or substrate 302 from the excitation radiation of the laser 304. The string of optical components also collects the fluorescent signals from the different ZMWs on the array and transmits the signals to a detector such as the EMCCD 330. The optical element string 306 includes a multiplexed component, such as a diffractive optical element (d〇E) 308 (also referred to as a holographic optical element or HOE) that converts a single excitation beam into a plurality of individual excitation beams, such The individual excitation beams will calibrate an array of illumination points corresponding to the ZMW 302 position on the array. The plurality of beam beams are selected to allow the illuminating light to pass through and reflect the dichroic mirror 316 from the fluorescent light of the array 302. Prior to passing through the dichroic mirror 316, the illumination beam may pass through one of the confocal filters 312, possibly paired with a pair of focusing lenses, such as lenses 310 and 314, to focus the beams through the confocal pinhole. The excitation light passing through the dichroic mirror 316 is then focused on the plane of the array 302 in a calibration mode via the objective lens 318. The fluorescent signal from array 302 is then collected by objective lens 318 and transmitted to dichroic mirror 316, which reflects the fluorescent signal toward detector 330. The signal from the discrete ZMW on the array is then passed through a spatial filter such as confocal reticle 322 to reduce background noise such as photoluminescence from the spontaneously focused or scattered light from the focal plane. Confocal reticle 322 typically Also associated with a pair of focusing lenses such as lenses 320 and 324. The signals then direct the spectrally-dispersive optical elements, such as the molded prism 326', in a manner that allows for the differentiation of different fluorescent states based on the incident position on the detector by way of the difference 25 201106032. The differentially guided signal component is then directed through an additional focusing optics, such as focusing lens 328, and finally to the EMCCD detector 330. As shown, the position of the specific signal on the detector indicates (1) the originating ZMW in the array, and (2) the spectral characteristics of the signal component, which is used to identify, for example, the person in the extended reaction towel. A type of fluorescently labeled nucleotide analog. It has been described that the use of the above system simultaneously calibrates the effects of thousands or tens of thousands of ZMWs in an array of illumination, and as the demand for multiplex increases, the ZMW dense array on the array provides a precise illumination effect. The difficulty of the ability also increases with UMW crosstalk due to higher levels of intensive illumination (the signals from neighboring ZMW are contaminated when they emerge from the array) and the reduction in signal-to-noise ratio. II. Multiplex Mode Although the above system is suitable for providing multiplexed multiplexed optical systems, it would be appropriate to increase the multiplex capability of the system by improving the specific system. The present invention provides methods, systems, and assemblies for monitoring a greater number of arrayed composites on a substrate. For example, the application of the U.S. Patent Application No. 12/151,979, issued on May 9 For example, the nucleic acid sequencing complex method, the money 丨 赖 赖 赖 至 离散 离散 离散 离散 离散 离散 离散 离散 离散 离散 离散 离散 离散 离散 离散 离散 离散 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 As shown, the systems optionally also include a confocal reticle to enhance the signal to noise ratio from the detection. The system of the present invention is used to further enhance the multiplex of the entire system via a variety of approaches. Thus, while the system of the present invention can be used to provide multiplex analysis of 10, 100, 1000, 5000, etc. discrete reaction zones on a substrate, in a particularly preferred aspect the invention will be used to provide more than 5000 discrete Reaction zone, over 10,000 discrete reaction zones, over 20,000 discrete reaction zones, over 50,000 discrete reaction zones and even more than 100,000 discrete reaction zones and up to 1, 〇〇〇, 〇〇〇 or more Multiplex analysis of multiple discrete reaction zones. In addition to the number of shears of the reaction zone that can be analyzed by the system of the present invention, it will be appreciated that in some cases, the configuration densities of such reaction zones may be higher than previously used, via the advantages provided by the present invention. For example, it is possible to provide and observe high-density discrete reaction regions without excessive interference or other problematic issues. The density may be, for example, 1000, 10,000, 100,000, 1,000,000, 10,000,000 or more reaction zones per square centimeter. The density of the observed volume can be increased to the diffraction limit of the observed light used, which can be as low as 250 nm for some of the wavelengths expected in such applications. At this interval, up to 16e9 observation volumes per square centimeter can be seen in a square array, and slightly more in a hexagonal dense array. This diffraction limit can be exceeded by the use of near-field optics, such that its limitations are only determined by the actual size of the limitation, and can be as small as 5 nanometers. A 100 nm spacing in a square array results in a density of lolO per square centimeter. Furthermore, the multiplex analysis system 27 201106032 is substantially simultaneous with respect to the number of areas monitored. "Substantially simultaneous" means analyzing the desired number of regions over a period of 1 to 5 (preferably 1 to 2) photographic frames. For the purposes of the system of the present invention, typically about 1 per cent. Capture a photographic frame from about milliseconds to about every 10 milliseconds (or frame rate from about 100 Hz to about 1000 Hz) 'by taking into account a substantially simultaneous analysis' of the analysis of such multiplexed areas should be from about 1 millisecond to Approximately 10 milliseconds of time occurs. As a result, one of the systems providing the desired multiplex analysis, such as observing at least one of a plurality of locations within a window from 1 millisecond to about 10 milliseconds, will be referred to as substantially simultaneous, Even though the analysis is performed at two different points in time within the window. In some cases, a slower frame rate can be used, which will increase the time period during which the second event can occur 'and from the perspective of the camera at this time It appears that it is still substantially simultaneous. A frame rate of, for example, 10 Hz to 100 Hz, 10 Hz to 5 Hz, 10 Hz to 20 Hz, such as about 15 Hz can be used. It will be understood that this occurs in the millisecond range, such as from 1 millisecond to about 500 milliseconds, 1 〇. Milliseconds to about 1 〇〇 The sampling rate of seconds, etc., can be regarded as substantially simultaneous. Synergistic optical components significantly increase the multiplex capacity in the analysis of discrete reaction regions on the substrate, subject to several limitations. For example, in systems that monitor glory signals from single molecule reactions, concentrating optical elements typically use high numerical aperture objectives with relatively small fields of view. Therefore, the increased multiplex typically requires a denser reaction zone so that the material __ objective (4) is derived from a greater number of signals in those areas. However, the denser reaction areas on a substrate create a series of additional resolution issues, including, for example, a string between regions 28 201106032. Figure 4 illustrates optical crosstalk. As shown, an array of reactive regions (e.g., 404, 410, and 412) on substrate 402, such as zero mode waveguide 404, is provided on a substrate. The fluorescently monitored reaction occurring in the regions is illuminated and a fluorescent signal associated with the reaction is emitted. As indicated by the solid arrow 406 and the dashed arrow 408 from adjacent reaction regions 410 and 412, respectively, 'the omnidirectional emission profile of the signal causes the signal from the adjacent region to interfere with each other', especially when the regions are on the substrate When it becomes more dense. This "crosstalk" limits the ability of the reaction zone to be intensive for analysis. In accordance with certain aspects of the invention, reinforced optics are used to enhance the efficiency of signal collection. One of the optical means provides for the addition of focusing optics for minimizing optical interference between reaction zones and, in many applications, the use of objectives having a larger field of view. By reducing the likelihood of crosstalk, the ability to intensify the reaction zone can be enhanced. At the same time, the area in which these areas are arranged can be enlarged by changing the objective lens with a higher field of view. In addition to reducing crosstalk, the focusing optical element of the present invention can also increase the amount of detected light by redirecting light into a singer, which is otherwise impossible in the case of unreversed Detector. By redirecting the light, for example, one of the collected light sources is the same as the uncorrected condition but has a lower numerical aperture to allow for, for example, a larger field of view. It is important to have a large field of view for the purposes of the method contemplated in the present invention, for example, to allow for simultaneous observation of tens of thousands of illuminating or fluorescing regions. Optionally, by directing the light, more light can be collected using the same numerical aperture. As described in more detail in Japanese Patent Application No. 29 201106032, the focusing optical element of the present invention can also increase the level of illumination by directing illumination light into an array such as a reaction zone on a zero mode waveguide array. Micromirror Arrays In one aspect, the present invention provides an array of shaped micromirrors, wherein each micromirror system is associated with a pupil limit, and in particular, a shaped micromirror that is incorporated into the same substrate containing the optical confinement An array. Figure 5A illustrates an example of a shaped micromirror array as in the present invention. As shown, the full substrate 502 includes an array of reaction regions disposed on a surface thereof, such as zero mode waveguides 504-514. The conical or parabolic mirror 516_526 is integrated into the underlying transparent substrate 528 and its configuration redirects the incident light to the ZMW' in the array or focuses the emitted light from the ZMW in the array. In particular, the conical or parabolic mirror is typically comprised of a reflective material such as a metal layer such as aluminum, silver, gold, chromium, etc., and is fabricated into the underlying substrate to provide the mirror surface. As shown in Fig. 5B, the fluorescent signal 53 emitted from the reaction in the ZMW is redirected or focused by a mirror such as a parabolic or conical mirror to increase the collection efficiency of the signals. As shown herein, for example, the omnidirectional light from the reaction zone entering the substrate is redirected, thereby making it easier to measure. In some cases, as will be explained herein, at least the light can be partially collimated. Furthermore, for each reaction zone or ZMW, the mirror structure reduces or eliminates crosstalk between ZMw within the substrate itself. In addition to reducing the disturbances, it will be understood that the enhanced gain and/or attack rate due to the redirection or focusing of the emitted light also increases the sensitivity of the system. Similarly, the shaped optical components are also used to focus incident illumination such as light 532 onto the reaction zone, such as ZMW 504-514. For devices incorporating such conical mirrors, an optional configuration may also be employed. For example, the core region of a zero mode waveguide can extend into the underlying substrate. This example is illustrated in Figure 5C, in which the reaction zone 55〇 extends beyond the cover layer 552 and into the underlying substrate 554, which in one case allows the signals reflected by the mirror 556 to be more efficiently transmitted to and from the egress reaction. Area 550. Additional components, such as light blocking regions or damper assemblies', including, for example, a reticle 558, may additionally be included within the overall configuration to further enhance the optical properties of the mirror system. Although the mirror system described herein is referred to as a "conical," or "parabolic, mirror, it will be appreciated that the integrated reflective focusing optics assembly is characterized by its ability to provide a reflective component within the substrate, by virtue of The light emitted from the reaction zone and redirected through the substrate enhances the detection of light, regardless of its exact shape. In some cases, at least the light emitted from the reaction zone is partially collimated. The shaping mirror of the present invention thus redirects light from a portion of the light from the substrate to a detector or to an optical component that directs light from the substrate to a string of optical elements of a detector Part. The focusing mirror may include shapes other than a parabolic configuration, such as a conical mirror configuration, a segmented conical mirror configuration, a truncated conical mirror configuration, a partial parabolic mirror configuration, a ladder mirror configuration > Mirror configuration, etc., provided that the structures redirect light, for example by partial collimation to enhance the detection of light emitted from the reaction zone or light entering the substrate through the reaction zone. In many cases, the mirrors will have cylindrical symmetry. The shape of the mirror may be a pseudo-cylinder such as a pyramid, a wedge, a ridge, an inverted prism, a bell, or a frustum thereof. When the mirror 31 201106032 has multiple sides, such as when it contains a truncated cone or a truncated cone, the mirror can have a suitable number of sides. For example, when the mirror packs a __ pyramid, the pyramid may have 3, 4, 5'6, 7, 8, 9, 1 〇, 1 12 or more sides. The shaping mirrors of the present invention are typically micromirrors, meaning that the mirrors are small, typically having dimensions of a few microns or tens of microns. In some cases, the term micro-reflector is also used to refer to a micro-mirror. The size of the wearing surface of the mirrors can be about 0. From 1 micron to about 100 microns, from about 1 micron to about 5 microns or from about 2 microns to about 20 microns. Although the size of the mirror of the present invention is from several micrometers to several tens of micrometers, the crown mirror of the present invention may be larger in some cases, for example, from about 1 inch to about 1 mm or more. Moreover, while illustrated with the provision of a reflective material such as a metal layer within the substrate itself, it will be understood that other reflective configurations can be employed without the use of a metal layer. For example, the constructs may be composed of materials of different refractive indices to provide a reflective interface that exhibits the same function as the metal layer described elsewhere in this case. For example, a self-refractive-index region travels through an interface into a region having a lower refractive index, and if the incident angle of the light exceeds a predetermined value (critical angle)', it will typically be completely internally reflected. In this manner, the reflective structure of the present invention can be produced by appropriately adjusting the refractive index of the material of any shape of the shape, 毋; using a reflective layer. In some cases, the shaped reflective construction of the present invention comprises a conical flat reflector. Both theoretical and experimental results show that the efficiency in the _-reflector version is significantly better than that of the non-reflective (four) substrate. In some cases, the conical step structure has (4), because it can be accommodated (4) by a variety of methods. For example: 32 201106032 The taper of the wall can be controlled by controlling the geometry of the photoresist and by lithographic conditions. The geometry of the photoresist can be controlled, for example, by controlling the focus/exposure conditions of the photoresist to control the topology of the photoresist, or by grayscale lithography. The shape can also be controlled by controlling the #刻条件', for example, controlling the amount of surface passivation or by ash I5 white etch. The conical mirror substrate of the present invention typically comprises a truncated cone configuration. The wall of the frustoconical region of the conical mirror substrate may be straight or may include some curvature. Figure 6 illustrates an example of three conical configurations. Figure 6A shows a conical mirror configuration in which the configuration of the mirror comprises a truncated cone of a straight conical configuration, which is disposed in a substrate layer below a reaction zone or reaction zone, such as a zero mode waveguide. 63 〇 to redirect light entering or leaving the reaction zone. Figure 6B shows a segmented conical configuration having a lower conical region 604 and an upper conical region 606. A reaction region 640 is disposed on the β-Hui structure. In this embodiment, the sidewall of the lower circular region 604 has a first angle with respect to the normal to the substrate, and the sidewall of the upper tapered region 606 has a relative to the substrate normal. Two angles, wherein the second angle is greater than the first angle. In some cases, the wall of the upper zone will have an angle relative to the normal that is less than the lower zone. As shown in Fig. 6C, the conical configuration can have a lower truncated cone region 608 and its wall perpendicular to the upper cylindrical region 610 of the substrate. A reaction zone 650 is disposed on the configuration. The configuration having the profile of Figure 6C can be adapted to produce a high density array. For example, it has a cylindrical top and / conical lower configuration that has a basic dimension that will generally be smaller than a single truncated conical configuration with the same sidewall angle. In some cases, if the basic size of the construction is small, more construction will be placed in a particular area. The reflection structure shown in Fig. 6 is displayed in such a manner as to protrude from a bottom layer 33 201106032. The bottom transparent layer can be a planar substrate such as a molten vermiculite wafer having a protruding configuration on its upper surface. The configuration of Figure 6 will typically have a reflective coating or a reflective region adjacent the wall of the configuration to enhance the internal reflection of light. For example, the protruding structure can be coated with a reflective layer, by filling a region between the protruding structures with a reflective material, or by using a medium having a lower refractive index outside the protruding structure to excite internal reflection. A reflective surface of the shaped substrate is provided. Although the illustration of Fig. 6 means that the reaction zone is located at the center of the top of the conical structure, in some cases, the reaction zone may not be located in the center. Manufacturing tolerances may cause the reaction area to deviate from the center position. Moreover, in some cases, for example, to receive a higher level of illumination, or for example when the illumination or detection optics are disposed at an angle that deviates from the normal of the particular reaction zone, an off-center reaction zone can be produced. The micro-mirror array can be combined for high density of ZMW arrays as described above. The micromirror density associated with the reaction zone can be, for example, from 1000 ZMW per square centimeter to 1,000,000 ZMW per square centimeter or more. At any one time, using the micromirror array described herein, analyze 100, 1000, 3000, 5000, 10,000, 20,000, 50,000, 100,000 or 1 million, 1 in a single analysis system or even on a single substrate. The reaction that occurs in thousands or more of the 214/^ or other reaction zones may be suitable as needed. Figure 7 shows a conical configuration of one of the micromirrors used in the present invention. The truncated conical structure as shown in Fig. 7 constitutes a one-piece structure extending over the transparent substrate. The truncated cone may be cylindrically symmetrical, having a substantially circular top surface having a diameter A, a substantially circular bottom having a diameter C, and a semi-high diameter 34 201106032 being D. The height of the truncated cone is B. The wall of the cone is substantially straight and has an angle e with respect to the normal to the surface. The side walls of the load cone configuration shown herein are substantially straight, but the walls may be non-flat and still be used to redirect the light intensity described herein. In some cases, the method used to create the conical configuration will result in self-leveling until, for example, shame having a f-thumb shape, in other cases, incorporating non-straight walls to enhance collection efficiency. In many cases, the method used to create the protruding configuration will result in a surface having protrusions, ridges, or other defects on the sidewalls that are offset from the flat profile. In some cases, it is desirable to have a flat profile for increasing the anti-ship density on the substrate. For example, a curved wall such as a paraboloid may have a bottom diameter that is larger than a straight side cone. By using a construction with a smaller diameter at the bottom, a higher density can be achieved in some cases. An exemplary conical configuration of the present invention having the profile shown in Figure 7 having a top diameter A between about (U micron and 1 micron, such as between 1 and 20 microns, or between Between 2 microns and 1 inch. In some cases, the top diameter A of the truncated cone is between about 丨 microns and about 5 microns. In some cases, the diameter is between 2 microns and 4 microns. The exemplary inconspicuous conical configuration of the present invention has a sidewall angle θ between about 2 and 4 $, between about 5 and 35, between about 1 〇 and 3 。. Between or between about μ and about 26. The resulting conical configuration will be, for example, located at the top of the conical crucible. [5 The central reaction zone is redirected by light. The exemplary construction will at least The light emitted by the reaction zone is redirected to an angle of about 22. 5 conical structure. In an exemplary embodiment of the invention, the height B of the conical 35 201106032 construction is between about 0. Between 2 microns and about 100 microns, between about 10 microns and about 10 microns, or between about 2 microns and about 8 microns or between about 3 microns and about 6 microns. In some cases, it is desirable to control the ratio of the height of the truncated cone to the diameter of the bottom (B/C). In an exemplary embodiment, the ratio of B:c is between about 1:3 and about 3:1 and the range is between about 1:2 and about 2:1, and between about 1. 5:1 to about 1:1. Between 5 or between about h2:1 to about 1:12. Those skilled in the art will appreciate that the choice of A, Θ and B will determine the bottom width (: > as described above, in order to increase the density of the optical construction of the present invention, the parameters are controlled whereby the bottom width C is small enough to allow The increased density can be suitable for the needs. The bottom diameter C can be between about 0. Between 2 microns and about 〇〇 microns, between about 1 micron and about 10 microns, or between about 2 microns and about 8 microns or between about 3 microns and about 6 microns. An exemplary conical configuration of the present invention has a top diameter A between about micron and about 5 microns, a height B between about 2 microns and about 8 microns, and a sidewall angle of about 10. It is about 3 baht. between. An exemplary conical configuration of the present invention will have a reaction zone disposed at the top portion of the cone, typically about the center of the material. The reaction zone lies as a zero mode waveguide comprising an aperture disposed through a reflective cover on the top surface of the conical structure. The aperture may have a diameter of from about 3 nanometers to about 3 inches. Figures 8(A) and 8(B) show two exemplary configurations of the shaping mirror of the present invention. Such configurations can be produced, for example, by the development of microfabrication for use in a +conductor process and methods for producing MEMS devices such as the luminescence (4) and (4) actors. Fig. 8(A) shows an array of a projection substrate 850 having a reflective coating 830 disposed on a top surface of a transparent substrate 8A having a top surface thereof on its 36 201106032. The protruding structure 850 is a shaped micromirror that redirects the illumination light entering the reaction zone 840 and/or redirects the light emitted by the reaction into the detection optical element disposed below the bottom surface 880 of the transparent substrate 800. Reaction zone 840 is a zero mode waveguide that is comprised, for example, of a nanometer aperture extending through a cover layer 820 disposed on top of the micromirror construction. In some cases, the reaction zone 840 will extend into the transparent substrate. A reflective layer 830 is disposed on the outer sidewall of the micromirror to enhance the reflectivity of the walls. In some cases, cover 820 and reflective layer 830 will be the same material, such as aluminum. The region 810 above the transparent surface can contain a liquid medium containing the sample and/or reactants that can diffuse into and out of the reaction zone. In some cases, all of the reaction zones in the array will be in contact with the same solution in zone 810. In some cases, barriers will be included between the reaction zones to reduce or prevent diffusion between the reaction zones. Fig. 8(B) shows an optional configuration of one of the shaping mirrors of the present invention. Fig. 8(B) illustrates a case where the transparent substrate 802 includes the protruding structure 852, and the entire substrate is substantially planar due to the flattening layer 862. A reaction zone 842 is disposed on the protruding formation 852, for example, in the form of an aperture through a cover layer 822. A reflective layer 832 can be disposed over the protruding features 852 to enhance reflectivity. In some cases, reflective layer 832 is not used, such as when planarization layer 862 comprises a reflective material. The planarization layer may comprise a hard material such as an inorganic material such as a spin-on glass or tantalum nitride. The flattening layer may comprise a metallic material such as aluminum. The planarization layer can be a soft material such as a polymeric material such as an organic polymer such as polyimine 37 201106032 or a Wei polymer. For example, the sample and test (4) can be introduced into the reaction zone 842 via a liquid medium located in the region above the substrate 8i2. The moon-permeable substrate may comprise an inorganic material, an organic material or a composite material having both organic and inorganic materials. The material is typically a rigid material that maintains the reaction zone in a fixed position during observation. The preferred material is Shi Xishi (4) (4), such as when making a semiconductor or MEMSlkH: to create a micromirror array. The transparent substrate may also comprise an inorganic oxide material and glass. The transparent substrate material can be a non-homogeneous material such as a material having multiple layers. In some cases, for example, the transparent substrate may comprise a dielectric stack 4. Transparent polymeric materials can also be used. Typical desires are transparent materials that exhibit low levels of spontaneous fluorescence. Suitable transparent polymers include methyl propyl polymer, such as pMMA, polycarbonate, cycloolefin polymer, styrene polymer, fluoropolymer, polyester, polyether ketone, polyether oxime, polyfluorene Imine or a mixture thereof. The reflective layer on the outside of the protruding structure in the transparent layer may comprise a metallic material such as H gold, silver, chromium or a mixture thereof. The reflective layer may also comprise a reflective organic polymer such as a composite comprising reflective particles dispersed in a polymeric material. The cover layer is an opaque or reflective material. The cover layer can be a metal such as aluminum, copper, gold, silver, chromium, titanium or a mixture thereof. In some embodiments, the reflective layer and the cover layer comprise the same material. The micromirror of the present invention enhances the collection efficiency of light from the reaction region on the substrate to be superior to the collection efficiency obtained in the absence of a mirror configuration. The etendue efficiency of an optical system is typically affected by the numerical aperture 38 201106032 diameter of the collection system. The micromirror of the present invention can be enhanced by having a specific numerical aperture such as 0. The amount of light collected by a detection system of the numerical aperture of 5 is about 1%, 20%, 30%, 40%, 50%, 75%, 90% more than the amount of light collected without the micromirror. 2 times, 3 times, 5 times, 10 times or more. The numerical aperture of the detection system can be, for example, from 0. 1 to 0. 9. In some cases, the numerical aperture is between about 〇. 2 and 0. Between 5 The micromirror configuration also increases the illumination level of the reaction zone from an illumination source. For example, the level of illumination can be increased to be 20%, 30%, 40%, 50%, 75%, 90%, 2x, 3x, 5x, 10x or more higher than the illumination level without the micromirror. many. In one aspect, the present invention produces a mirror configuration whereby the illumination light is constructively interfered and thereby increases the intensity of light in the reaction zone. Light can interfere with two or more light waves added or superimposed to create a new wave pattern. For example, waves that are related or coherent with each other may interfere, for example because they are from the same source or because they have the same or nearly the same frequency. For example, with the mirror construction of the present invention, incident light can be redirected from the sidewall of the structure, whereby light redirected from different portions of the sidewall interacts within the mirror volume, causing constructive or destructive interference. . Since the redirected light comes from the same source, the parts of the light redirected will tend to have substantially the same frequency. Constructive or destructive interference of light in a given area depends on whether the light is in phase (constructive) or out of phase (destructive). By controlling the geometry of the micromirror construction and the nature of the illumination, it is possible to control areas of constructive or destructive interference. Electromagnetic model chemical can be used by input mirror construction and illumination light parameters. 39 201106032 Measured areas of constructive interference, such as finite time domain difference (FDTD) or finite element method (FEM). We have determined that for a conical configuration in which the top diameter is similar to the beam diameter in terms of diameter, the field strength in a local region such as the reaction region can be increased to 10 times that in the absence of constructive interference. In some cases, the size of the local area with high strength may be about 0. 25 to about 1 wavelength. It may be advantageous to increase the diameter of a beam to be the same as the size of the micromirror in terms of enhancing illumination. In some cases, the mirror construction has a top surface' such as a truncated cone having a planar top surface, and the top mask has a diameter. In such cases, the ratio of the top surface diameter of the systems to the beam diameter of the incident light is from about 1:5 to about 5:1, from about 1:3 to about 1:3, from about 1:2 to about 2:1 or about 1:1. 5 to about 1. 5:1. Figure 9 shows an illustration of one micromirror configuration illuminated with collimated light. The different shades in the micromirror configuration in the figure represent different light intensities. The figure shows several high intensity regions adjacent to the top of the micromirror, with a high intensity region occurring in the reaction zone at the top center of the mirror configuration. By constructing the micromirror structure in such a way that constructive interference occurs in the reaction zone, the light intensity in the reaction zone can be increased above that obtained in the absence of the micromirror. Constructive interference can be used to increase the light intensity of the reaction zone, which is about 3〇%, 4〇%, 50〇/〇, 75%, 2 times, 3 higher than the intensity of the same illumination light without the micromirror construction. Times, 5 times, 1 time, 15 times, 20 times, 3 times or more than 30 times. Fabrication of Micromirror Arrays The micromirror arrays of the present invention can be fabricated by a variety of methods. In terms of the manufacturing aspect of the array, an array of structures such as the projections of the structure 40 201106032 is fabricated on a transparent substrate. The array of structures can be fabricated by molding, stamping, embossing, processing, etching, or other suitable methods. A preferred way of fabricating the micromirror array of the present invention involves the use of microfabrication methods such as semiconductor or MEMS process methods, which have been highly developed for the fabrication of, for example, integrated circuits. Similar methods have been used to create MEMS (Micro Electro Mechanical Systems) for a variety of applications including inkjet printers, accelerometers, pressure transducers, and displays such as digital micromirror displays (DMDs). The microfabrication method can be applied to a large substrate such as a wafer, which can be subsequently cut into a variety of devices to allow multiple devices to be fabricated at one time. In one aspect, the invention uses such methods to fabricate a micromirror array of a transparent substrate such as a glass such as molten vermiculite. The method of the present invention employs a photoresist method, such as photoresist, to define structural elements on a transparent substrate or other layer. The method is etched to produce a three-dimensional configuration including the reaction region and the micromirror configuration. The temple method is used to add a layer on the substrate. Other semiconductor processes such as ashing, polishing, release, and stripping also produce micromirror configurations of the present invention as described in more detail below. The transparent substrate can be any suitable rigid material. The transparent material may comprise, for example, an inorganic oxide material such as Shishi. A preferred material is molten vermiculite. In one aspect, the invention is a method for fabricating a substrate comprising an array of reaction regions associated with a micromirror configuration incorporated by a method, the method comprising the steps of: a) providing a top surface a transparent substrate; b) patterned and etched on the transparent substrate to form an array of protruding structures having a top and a side; a deposition of a covering material 'by this 41 201106032 the top of the protruding structure comprises a cover; sentence formation By covering one of the aperture arrays 'by the top inclusions/apertures of each of the protruding structures; and e) depositing a reflective deposition material 'where the sides of each of the protruding structures comprise a reflective layer; whereby the array of protruding structures comprises A micromirror array, the aperture at the top of each protruding configuration comprises a zero mode waveguide. This method involves the fabrication of both the reaction zone and the micromirror configuration. More specifically, one of the set methods first involves fabricating a reaction zone', e.g., in the form of an array of apertures, and then fabricating a micromirror configuration. Another set of methods involves first fabricating a micromirror structure on a transparent substrate and then fabricating a reaction zone. In order to fabricate the arrays of the present invention, it may be useful to combine different methods for different shapes for different dimensional requirements. For example, the method of the present invention can be used in a 193 nm lithography process for fabricating a reaction zone, and an I-line lithography process for fabricating micromirror structures. This is not a typical production method because the substrate is sent from one production facility to another in the middle of the process. FIG. 10 to FIG. 18 illustrate an exemplary method of the present invention for fabricating an array of reaction regions, each The reaction zone is associated with a micromirror optical element in a transparent substrate. These exemplary methods are not an exhaustive list of methods that constitute the invention. Each of these methods involves a different set of steps. In some cases, a set of steps of one method can be combined with a set of steps of another method to produce a substrate of the present invention. For example, the fewer steps used in the fabrication of the micromirror construction in one method can be combined with the steps used to fabricate the aperture. In addition, the description provided may not include all the steps that will be included. For example, in many cases, ashing, purifying, removing photoresist, rinsing, and drying steps not described herein, 42 201106032, will in many cases be incorporated into the methods of the present invention. Although the steps in the method show that the particular layer is directly above the other layers as appropriate, the method comprises the inclusion of an intermediate layer between the layers, but is not described herein. For example, in the case of a variety of prior methods, for example, between the layers under the photoresist and the photoresist, a pour layer or an anti-reflective coating such as BARC is included. It should be understood that the method can be entered. Unless otherwise stated, the order of the steps of the method can be changed as appropriate. In some cases, the methods provide a step of engraving the number of layers, such as simultaneously passing through the metal cover layer and the transparent substrate, or simultaneously through a protective layer, a gold cover layer, and a transparent substrate. Although the method generally shows that the layers are similar to each other, in some cases, individual U-shirts and etching steps are performed in each layer. For example, when etching through a metal layer and a transparent substrate, in some cases, the desired first deposition - photoresist and patterning at the first photoresist to etch the metal layer, and deposition and second light A pattern is resisted to etch the transparent substrate. In some cases, multiple etching steps can be performed in a manner that provides, for example, a segmented conical configuration. For example, the first 4 method of ignorance and surname can button the metal layer and extend directly downward into the transparent substrate perpendicular to the surface to form a cylindrical structure; and the first lithography and etching method are opposite The angle at the surface normal creates a side wall that forms a lower conical configuration. In this manner, a mirror configuration such as that shown in Fig. 6C can be fabricated by using a plurality of etching steps. Fig. 10 illustrates a semiconductor manufacturing process for explaining the fabrication of the micromirror optical 7L device and a zero mode waveguide array which causes the micromirror device to be fabricated first and the ZMW to be fabricated in a subsequent step. As shown in step I, a transparent substrate layer 1000 is first coated with a 43 201106032 photoresist layer 1002. The photoresist is then exposed and developed in step II to provide the desired pattern 1004 of the mirror array. In step III, for example, a dry etch transfer method is used to transfer it to the underlying substrate to produce a negative relief 1006 of the mirror array. In the method described herein, an array of mirrors having a parabolic configuration is fabricated. In some cases, providing a smoothing step after the transfer step may be desirable to mitigate potential optical aberrations from the rougher etched surface. The smoothing step can include, for example, a gentle etching step to provide smoothing of the surface, such as a lower piezoelectric paste etch and/or deposition of a smooth layer material on the transferred surface. Examples of such smoothing layers include, for example, an index matching type material such as a Si0x or Si〇2 layer, which may be subjected to a conventional conformal deposition method such as a low pressure chemical gas deposition (LPCVD) process, plasma strengthening. A CVD process (pecvd), etc., on which the temple is deposited. After the transfer step III, a layer of reflective material 1 〇〇 8 is deposited on the patterned substrate in step IV. In a particularly preferred aspect, the reflective material is a metallic coating, such as aluminum or chromium, which is deposited on the patterned surface via a metallization process such as evaporation or sputtering to define the reflective surface of the mirror array. In some cases, a conformal deposition method such as a base is used. <Six, the role of 'to complete the role of the temple or metallization. After the metallization step, in step V, a fill layer or planarization layer 1010 is deposited on the reflective layer 1008. This step can use a variety of filler materials, including additional metal layers (or continuous metal layers), inorganic materials such as ruthenium, ruthenium dioxide, polymeric materials, semiconductor materials, and the like. In a particularly preferred aspect, a stone layer is deposited as a fill layer' and preferably the layer comprises cerium oxide or other glass material. The fabrication of the glass-filled layer can be accomplished by several conventional methods, including the use of spin-on glass materials such as sesquiterpene oxide, or vapor deposition and subsequent oxidation via a ruthenium-filled layer on the substrate. The upper surface is then removed in step VI, such as via surface grinding, polishing or etching, or a combination thereof, to expose one of the openings 1012 in the top portion of the parabolic mirror. A metal cap layer 1014 is then deposited in step vπ to define a ZMW with an integrated parabolic mirror on the upper surface of the ΖΜλν core 1016 having an aperture such as an optical communication through which it is configured and constructed with the parabolic mirrors. Array. Figure 11 shows another exemplary method of fabricating the integrated reaction region and micromirror of the present invention from a transparent substrate. In the step (1), a photoresist 112 such as a photoresist is deposited on the transparent substrate 1100 of the top surface of the cover layer 1110. The photoresist is patterned and developed to produce an array of features 1125. The cover layer 1110 is etched in step (II) to produce an array of reaction regions 1140 such as through the aperture of the cover. The array of reaction regions 1140 can also be fabricated by other methods such as those described herein, such as by using a sacrificial post or by etching the cover layer by an e-beam. In the step (III), a protective layer 1150 is deposited on the substrate. In step (IV), one of the features/resistors for defining the mirror structure 1160 is deposited and patterned. In step (V), a single or multiple etching steps are used to create a micromirror configuration shown here as a cone. The photoresist is then removed to expose the protective layer. In step (VI), a reflective layer is deposited, for example, by de-plating or evaporation of metal 1170. In step (VII), a photoresist for defining the top of the mirror structure 1180 is deposited and patterned. In step (VIII), the metal portion not covered by the photoresist is engraved to expose the underlying protective layer. 45 201106032 Then remove the beta layer to open the aperture. The resulting array has a reaction zone comprised of aperture layers that pass through the cover, each aperture layer being disposed on top of a mirror construction. An exemplary exemplary method of the present invention is shown in Figure 12. Steps (1) and (II) use the photoresist 1220' to fabricate an array of apertures 1240 in the cover layer 121 of the top of the transparent substrate 1200. The array of reactive regions 1240 can also be fabricated by other methods such as those described herein, such as by using a sacrificial post or by etching the cover layer with an e-beam. In step (111), the temple is used to define a photoresist of the micromirror structure 126, and to make a pattern. In step (IV), the geometry of the photoresist and the etching conditions are controlled to produce a body having a trapezoidal sidewall of a micromirror configuration, which is illustrated herein as having a conical configuration of substantially planar sidewalls. A reflective layer is deposited in step (V), such as in the form of a metal layer 1270. A photoresist 1280 is deposited and patterned in step (vi) to expose the area above the photoresist region on the top structure of the micromirror. In the step (νπ), the exposed metal is etched, and then the photoresist is removed to expose the aperture, thereby producing an array of each of the reaction regions associated with the micromirrors. Figure 13 shows another exemplary method of the present invention. First, steps (1) and (II) use photoresist 1320 to fabricate an array of apertures 1340 in a cover layer 顶部3ι〇 on top of transparent substrate 1300. The array of reaction regions 1340 can also be fabricated by other methods such as those described herein, such as by using a sacrificial post or by etching the cover layer with an e•beam. Then, a protective layer 13s is deposited in the step (m). In step (IV), a photoresist is formed to define the micromirror structure 1360 and a pattern is created. In step (7), the __ method is used to fabricate a micromirror configuration having a trapezoidal sidewall, and the anti-corrosion and protective layer is removed. In step (VI), a photoresist 1 1380 is produced on top of the micromirror structure by deposition, patterning and removal of light 46 201106032, and metal 1370 is deposited in step (VII) to A reflective layer is formed on the micromirror. In step (VII), the photoresist is removed, the photoresist column and the metal deposited on top of it are removed, thereby creating an array of reaction regions associated with the micromirrors. In another exemplary method shown in Fig. 14, steps (1) and (II) use photoresist 1420 to fabricate an array of apertures 1440 in cover layer 141A on top of transparent substrate 1400. Then, in step (III), a sacrificial layer 1450 is deposited. A preferred sacrificial layer comprises tantalum or niobium. In step (IV), a photoresist is formed to define a photoresist and pattern of the micromirror structure 1460. In step (v), an etching method is used to fabricate a micromirror configuration having trapezoidal sidewalls, and a pulling method is used to open the edges of the sacrificial layer on top of the micromirrors. In step (VI), metal 1470 is deposited as a reflective layer of the micromirror. Sputtering can be one of the methods suitable for the metal deposition step because it produces an effective sidewall covering effect without covering the sidewalls of the sacrificial layer. In step (VII), releasing the sacrificial layer' also removes the photoresist and metal layer on top of the sacrificial layer. It may be advantageous to use a wet release method in releasing the sacrificial layer by allowing diffusion of the release material through the access holes, in some cases creating bubbles that help to effectively remove the photoresist and metal layers on the top of the sacrificial layer. In some cases, sonication and wet release methods are used. The method produces an array of reaction zones each associated with a micromirror on a transparent substrate. Figure 15 shows an alternative method of the invention. In step (1), a photoresist is formed on the transparent substrate 1500 to define a photoresist of the micromirror 1510 and to make a pattern. The micromirror construction is then fabricated in a transparent substrate 47 201106032 1500 using, for example, a reactive ion etching method. In step (111), a metal reflective layer 1520 is deposited over the micromirror structure. In step (IV), a planarization layer 1530, such as a spin-on glass or PECVD oxide, is deposited. The thickness of the planarization layer may be, for example, 8 to 10 μm. The planarization layer can be a hard material such as spin-on glass or can be a soft planarization layer. The soft planarization layer can be, for example, a spin-on UV curing type organic polymer such as Summers J91 or SK9. When the planarization layer comprises a hard material, the planarization is typically performed, for example, by chemical mechanical polishing (CMP) as illustrated in step (V). When the planarization layer comprises a soft material such as a UV-curing polymer, then oxygen etching can be used after UV curing to etch away the top region of the spin-on polymer to the top of the micromirror, which is similar to polishing effect. The polishing or oxygen etching step exposes the top of the micromirror construction. In step (VI), a metal cap layer 1540 is deposited on the surface. In step (VII), a photoresist for defining one of the apertures 1550 and patterning are deposited. The cap layer is etched in step VIII to form a reactive region 1560, and the photoresist is removed to produce an array of reaction regions each associated with a micromirror on a transparent substrate. Figure 16 shows yet another alternative method of the present invention. In the step (1), a photoresist is formed on the transparent substrate 1600 to define a photoresist and a pattern is formed. The micromirror construction is then fabricated in a transparent substrate 1600 using, for example, a reactive ion etching process. In step (ΠΙ), a metal reflective layer 1620 is deposited over the micromirror structure. In step (IV), a soft planarization layer 1630 such as a polymeric layer is deposited. The soft planarization layer can be, for example, a spin-on UV curing type organic polymer such as Summers J91 or SK9. In the step (V), the photoresist for defining the reaction region 1640 is deposited and fabricated. FIG. 48 201106032 2 In the step (νι), a deep surname is performed, which penetrates the soft planarization layer ι63〇, the metal layer 162G' To form a reaction region 166G. In step (VII), the photoresist and the soft planarization layer are removed, thereby producing an array of reaction regions 166A associated with each other on the transparent substrate. Fig. 17 and Fig. 18 show an alternative method of the present invention using a small column (nano column) formed from a layer deposited on a transparent substrate such as a fused stone. The nanocolumn is formed on the surface and removed later to produce the reaction zone of the present invention. The nanocolumn can be formed from any suitable material of the layer. Preferred materials for forming the nanocolumn are polycrystalline germanium (p〇ly_Si) or polycrystalline germanium (P〇ly-Ge). For example, polycrystalline germanium can be deposited on a transparent substrate by low pressure chemical vapor deposition (LPCVD), plasma enhanced chemical vapor deposition (pECVD) or solid phase crystallization (SPC) of amorphous germanium. Other methods described herein, such as those described above, incorporate the use of a nano column such as a polycrystalline nano column to produce a reaction zone. While referring to some of the methods used for nanopillars made of polycrystalline germanium, it should be understood that such methods can be fabricated using other suitable materials. In the method shown in Figure 17, in step (1), an array of polycrystalline stellite columns is produced on top of a transparent substrate, for example by depositing a polycrystalline layer on the transparent substrate. The photoresist is patterned and patterned in the photoresist to define a nano-pillar and to etch away unwanted polysilicon regions to produce the nano-pillar. In the step (II), a photoresist for forming a micromirror structure and a pattern are formed. The etching of the transparent substrate is performed in the step (ΠΙ) to produce a micromirror structure having trapezoidal sidewalls. In step (IV), a thick metal is deposited, thereby burying the area between the nanocolumn and the filled micromirror structure. In step (V) 49 201106032 two cases:: planarize the metal layer by μ 'by exposing the beta column of the nano column and then removing the exposed nano column in step (f) to generate the reaction = domain - Array. In Qing Shicai, the metal system (4) is the surface of the reflector on the wall of the cover layer and the micromirror structure. In some cases, the thick metal layer can be thermally managed, because the metal layer produced can have a relatively high heat transfer. coefficient. Figure 8 shows an alternative method using a nanocolumn to create an array of reaction zones. In step (I), an array of polycrystalline spine is produced on the top of the transparent substrate, such as by depositing a polycrystalline layer on the transparent substrate and depositing light in the light. The side case is blocked to define the nano-pillar and the money to remove the unwanted polycrystalline fracture area to produce the nano-pillar. In step (π), the memory is used to form the micro-mirror structure - the photoresist and the pattern. In the step (10), the (four) action of the transparent substrate, for example, reactive ion beam (4), is performed to generate a micromirror structure. In the step (IV), the metal layer is killed, whereby a metal coating layer is formed on the micromirror top structure, and a reflective layer is formed on the side of the micromirror structure. In step (V), a planarization layer such as a spin-on glass is deposited to fill the area between the micromirror configurations. In step (VI), a planarization or polishing step is performed to planarize the planarization layer and the metal layer on the top structure of the micromirror and expose the nanopillar structure. In step (VII), the nanocolumn structure is removed to create an array of apertures or reaction regions each associated with a micromirror configuration. Figure 19 shows a method of forming a reaction zone of the present invention, e.g., a nanometer-sized aperture, using a sacrificial layer. The method illustrated in Fig. 19 can be incorporated or combined with any suitable method described herein, including the method of 50 201106032, etc., in the above-described 10th to 18th, and the (4) array of trees and micro-tracks. In the step_cloth, the "=" is applied on the side of the transparent substrate, and the hard mask layer 192 is coated on the side of the sacrificial material. The sacrificial material may be, for example, polycrystalline or polycrystalline germanium. The hard coat material may be, for example, an oxide or nitride 'such as 11 oxide or nitrogen cut. During the subsequent (d) step, the hard coat material should have acceptable selectivity for the sacrificial material. In step (II), a hard mask is engraved using a lithography method. In step (10) and step (IV), the sacrificial layer is fine. Using a controlled over-acting _ as shown in step (IV) to produce a -specific base appears to form a sacrificial column. Base etching can be performed whereby the diameter of the hard coat layer mask or other surface dimensions (W1) is 1.1 to 3 times the diameter of the sacrificial layer (Wp). In some cases, the Wi/Wp system is between about 15 and about 25. In some cases, the Wi/Wp system is between about 6 and about 22. The size of the basement can be, for example, between about 1 nanometer and about 300 nanometers, between about 50 nanometers and about 200 nanometers, or between about 70 nanometers and about 15 nanometers. A metal cover 1930 is then deposited over the surface. The cover deposition is carried out by one of sputtering, whereby the metal is deposited on a transparent region below the region where the hard mask extends beyond the sacrificial layer. In step (VI), the sacrificial column is removed, for example, by dissolving the sacrificial material preferentially to expose the reaction zone 1940. When the sacrificial material is tantalum and the metal is covered with aluminum, an aqueous oxidant can be used which will dissolve the tantalum without significantly removing the aluminum. The transparent substrate can be etched to form the micromirror configuration in a single step or in multiple steps. In some cases, a series of photolithography and surname steps can be used to form the mirror configuration. Although the steps of the method are added to 51 201106032 using multiple etching steps, in some cases the series of steps can be used to provide more control over the construction of the micromirrors. In some cases, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, 30 or more steps may be used. Figure 2 shows an exemplary method of using multiple lithography and etching steps. For the method described in Fig. 20, the substrate 2000 was coated with a photoresist, patterned, and etched 9 times. The first layer is etched, for example, to create a cylindrical configuration having one of the lowest layer diameters. Subsequent patterning of the respective photoresist layers is then performed to have a circular shape having a diameter slightly smaller than the previous layer. The result of this multiple step method is an array of constructs 2010, which is defined by an insecticide. In some cases, this approach will result in having one of a series of terraces 2020 defined by layer 2010. If desired, the walls of the structures can be smoothed, such as by wet or dry etching, to partially or completely smooth the terrace structure. The construction can be applied in a reflective manner, and the associated reaction regions can be fabricated as described above before or after the micro-mirror configuration is formed by multiple etching steps. The structure 2010 described in FIG. 20 is shown in the form of a different relative straightening sidewall (stepped), but multiple etching steps can be used to fabricate a curved wall, a segmented conical configuration, a parabolic configuration, etc. The construction of any arbitrary shape. The multiple etching step <Incorporate any combination of isotropic, anisotropic or grayscale etching steps. While the method produces a cylindrically symmetric configuration, it will be appreciated that the multiple step method can also be used to create configurations having other symmetries that are not cylindrically symmetric. In some cases, the method of the present invention uses a resist to use a lithography boundary to create a structure. The resists can be, for example, a stop or an e-beam resist. The photoresists can be developed using ultraviolet light, deep ultraviolet light, G-line, H-line, 52 201106032 ι-line or other suitable wavelength or wavelength set. The type of photoresist used, and therefore the type of instrument configuration used in the method, will depend on the size of the body being produced. In many of the methods described herein, 'higher resolution anti-contact agents and equipment will be used to produce a pore size corresponding to the reaction volume' wherein the pore size can range from 10 nm to 500 nm, and the resolution is lower. The photoresist is associated with an instrument configuration to produce a micromirror' which can have a physical size of from 1 micron to 20 microns. A variety of anti-surname agents are known in the art, and many are available from companies such as Rohm and Haas and Shipley. The photoresist used in the method of the present invention may be a negative or positive photoresist. When referring to one of the methods of using a negative photoresist, it should be understood that a suitable positive photoresist can also be used when feasible, and vice versa. Chemical amplification can also be used when appropriate to increase the sensitivity of the photoresist. Removal of the photoresist and cleaning, rinsing, ashing and drying of the substrate can be carried out as appropriate and as taught in the art. In some cases, photolithographic tools for reaction zones (e.g., ZMW) utilize a photolithographic exposure tool that produces a structure having a size of from about 1 nanometer to about 1 nanometer. The system includes, for example, an AMSL XT1250 exposure tool. An etching method is used in some aspects of the invention to create a three-dimensional shape in a transparent substrate or in other layers to constitute, for example, an optical element such as a micromirror or lens, or a reaction volume such as a nanometer aperture. The etching method used will depend on the type of material used, the size of the body, and the photoresist system. In some cases, wet-type or wet chemical engraving is used. Electrochemical etching can also be used. In some embodiments, plasma etching or reactive ion etching (RIE) is used as a residual method. For example, when the desired structure has a high aspect ratio structure, deep reactive ion etch 53 201106032 (DRIE) can also be used. It is also possible to use, for example, dry vapor phase inoculation with bismuth difluoride. When suitable for producing the construction of the present invention, bulk micro-working or surface micromachining can be used. The etching used in the method of the present invention can be a gray scale etching effect. The conditions of the photoresist forming action and the etching action are controlled to produce a sidewall having a desired geometry such as having a desired sidewall angle to function as a micromirror. Some methods of the invention involve the deposition of a reflective layer or a cover layer. The deposition of the reflective layers can be accomplished by wet methods including spin coating on the layer from the solution, or by gas phase methods. Suitable methods include electroplating, sputter deposition, physical vapor deposition, evaporation, molecular beam epitaxy, atomic layer deposition, and chemical vapor deposition. Metal can be used as the reflective layer and the cover layer. Suitable metals include gold, nickel, aluminum, chromium, titanium, platinum, and silver. The reflective and/or cover layer may comprise aluminum which may be deposited by sputtering, for example using a commercial sputtering tool available from CVC, Novellus or MRC Corporation. When the layers are deposited during the method of the present invention, in some cases, the layers are processed prior to moving to the next step in the process. For example, the deposited layer can be annealed, planarized, cleaned, passivated, or lightly etched to enhance its properties. In some methods of the invention, a protective or sacrificial layer is deposited. The protective layer may be a polymeric layer or may be an inorganic layer. Suitable protective or sacrificial layers include germanium (Ge) and amorphous germanium (a-Si). A protective layer can be used to create the features described herein. The type of material used for the protective or sacrificial layer can be selected for its selective reactivity, such as for selective reactivity with wet chemical etchants. For example, in the case of 2011 060 矽 矽 铝 铝 , , 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 2011 Mirror construction. In some methods, a pull-out method is used. The pull-out method usually involves closing the edge of the body from the layer to reduce the size of the body. A wet chemical reduction agent selectively reacting with a layer having exposed edges can be used. In some cases, a layer of gas is used to open the layer. Some methods use a polishing step to remove a surface area from the substrate. Suitable methods include chemical mechanical polishing or chemical mechanical planarization (CMP). Some methods of the present invention incorporate a planarization layer. The method used to deposit the planarization layer will depend on the type of material used. The planarizing layer can be a hard material such as an inorganic material such as tantalum nitride; it can be a metal material such as sinter; or it can be a soft material such as a polymeric material such as an organic or bismuth polymer. The planarization layer can be a glass, such as a ruthenium dioxide material. In some cases, the planarization layer comprises a spin-on glass such as a silicate, phosphonium or decane material. Suitable spin-on glass materials are available, for example, from Honeyewell Corporation. The planarization layer can comprise, for example, a glass that is doped with other agents to control its melt properties, such as boron-phosphorus-tellurate glass (BPSG). Suitable polymeric planarizing materials include, for example, polyimine. The array of the present invention can be incorporated into an analytical system for use in analyzing multiple reactions occurring in the reaction zone of the array. The array described herein typically has 55 201106032 with a fluid-receivable reaction zone from the top and is accessible for optical analysis from the bottom. Thus the array is typically incorporated into a container and one of the reaction mixtures to be explored is introduced into the container. In some cases, the individual reaction zones are in contact with a volume of fluid, which may have, for example, a plurality of nucleic acid template molecules that can be analyzed, and which may have nucleotides, cofactors, and reactions for performing the assay. Other additives. The container containing the array can be placed in an instrument with appropriate optical components, computer control, and data analysis systems. The container containing the array will be secured within the instrument whereby reaction conditions such as vessel temperature and atmospheric conditions of the container can be controlled. The atmospheric conditions of the vessel may include the composition of the gas above the sample, such as humidity and other gas species such as oxygen levels. Integrated Lens Arrays As with integrated parabolic mirrors, lens arrays can be fabricated using a variety of conventional techniques, including, for example, semiconductor fabrication methods, micromolding of polymeric materials, and the like. For example, as part of the fabrication method for the integrated mirror described above, an etching method such as reactive ion etching can be used to fabricate the lens arrays. Optionally, as mentioned above, the variable ion implantation method can be used to change the refractive index of the substrate assembly while defining the lens with an existing substrate. As will also be appreciated, additional optical elements that provide enhanced light collection for light from the reaction zone can also be fabricated in the substrate. For example, the ion implantation method described above can be used to define a diffraction grating that is directly used for each of the different reaction regions in the substrate. In an optional aspect, the conical or parabolic mirror is replaced (or in some cases amplified) by a lens array that at least partially collimates or focuses the fluorescent signals transmitted to and/or from the substrate. Figure 21 illustrates this type of lens array. As shown, 56 201106032 general assembly 2100 again includes a zero mode waveguide, such as ZMW 2102-2112, disposed in an array on a first surface 2114 of a transparent substrate 2116, and the reactions contemplated therein are performed therein. A micro or nano lens, such as an array of lenses 2118-2128, is disposed on the opposite (or rear) surface 2134 of the transparent substrate 2116. As shown, the lenses are of the same size and are arranged in a pitch with the ZMW array whereby each ZMW has its own mating lens. Like the mirror array of Figure 5B, the light from the ZMW is redirected, for example by collimating the lens portion associated with it, and collecting and analyzing the light to monitor the reaction to be explored. While such lenses are less effective than parabolic mirror construction in eliminating crosstalk in the substrate, they provide additional benefits in terms of cost and ease of manufacture, and in some cases can be used to replace or assist in such integrated mirrors. As shown, the lens array can be integrated into the underlying transparent substrate. Alternatively, the lens array can be fabricated separately and bonded to the underlying substrate to provide the same or similar results. Although illustrated with a single layer lens disposed on the back surface of the array, it will be understood that the lens array can be composed of multiple lens layers in different regions on each addressed substrate, or the limb regions on the substrate can be combined to provide Optical work. Further, although the lens protruded from the rear surface of the transparent substrate, in some cases, the lens can be integrated in the transparent substrate. For example, the lens can be assembled into the underlying substrate at the appropriate position by providing a change in refractive index of the substrate at the locations. The lens manufacturing as described can be used to embed individual lenses in a substrate using micro-jade technology to provide birefringence. Preferably, the portions of the substrate act as lenses by creating an index of refraction in the art portion of the substrate. The refractive index of the substrate, such as a glass substrate, can be varied by several means, such as including ion implantation methods. In addition to the lens or lens array, the diffraction grating or other optical functionality can be similarly assembled into the underlying substrate. Since the signal from the substrate is at least partially collimated by the focusing optics, the need for a field of view, high numerical aperture objective lens is reduced, and a wider field of view, lower NA objective lens can be used, which typically gives system cost and availability. Advantages 'Because the less rigid objective lens can be used. In addition, heterogeneous materials used to fabricate higher magnification objectives can cause an increase in photoluminescence of the objective lens itself when exposed to excitation radiation. Furthermore, because the lower magnification objective is used, the spacing provided between the objective lens and the substrate can be greater than that typically provided when using a high numerical aperture objective lens. This additional spacing allows for the insertion of additional optics between the substrate and the concentrating objective. The component 'as appropriate dichroic mirror. In at least one exemplary embodiment, a dichroic mirror is provided between the substrate and the objective lens to permit separation of illumination light from the collection objective and other collection optics components. By further separating the excitation path from the detection path, and in particular by providing a collecting objective lens that does not see the excitation light, the spontaneous fluorescence or light caused by the excitation illumination through the objective lens in the light collecting path can be completely eliminated. Glowing. One of the optical devices is illustrated in Figure 22A. As shown, the whole system 2200 includes a substrate 2202 on which a plurality of reaction regions 2204 are disposed. Also incorporated into the substrate (as shown) or in the form of individual components, including, for example, focusing optics for collimating optical signals from the reaction zone and/or focusing illumination effects on the reaction zone (as described above) Integrated micromirror or lens). The system also includes an excitation source 2206 or a plurality of excitation sources to provide excitation light to the substrate 22〇2. The excitation light is guided to the substrate via a dichroic mirror 2208 58 201106032 located between the collection objective 2210 and the substrate 2202. By separating the excitation light from the collecting objective lens 2210, the problem associated with the spontaneous fluorescence of the collecting objective lens 2210 can be avoided, and spontaneousness can be one of the important causes of noise. Prior to the reflection of the dichroic mirror 2208 to the substrate 2202, additional operations, such as spectroscopic, beam shaping, tears, waves, etc., will typically also be experienced. For example, excitation light can pass through a multiplex optical element, such as a diffractive optical element (DOE) 2212, to provide a plurality of individual beamlets; and through focusing optics for focusing the beamlets onto the focal plane of the substrate. The signals emitted by the objective lens 2214 are collected by the dichroic mirror 2208 and by the collecting objective lens 2210 by virtue of their different spectral characteristics from the excitation light. As previously indicated, when the signal portion from the substrate has been collimated by the focusing optics, the collecting objective can have a significantly lower multiple, such as from a field of view of a system for a non-focusing optical element of less than 3 mm. A 60X (numerical aperture 〇9) or higher objective lens, changed to a 4X with a field of view of 45 mm or more (numerical aperture is 0. 28) or a lower magnification objective while still providing sufficient sensitivity for single molecule analysis. As with the system shown in Fig. 2, the collected signals can then be spectrally separated, for example, by 稜鏡2216, and further focused, for example, via lens η", or prior to detection by detector 222. Other operations. An additional or optional illustration of one of the dichroic mirrors and illumination paths of the substrate is shown in Figure 22B. As shown, the dichroic mirror layer 22〇8 is sandwiched between two 稜鏡225稜鏡 and 2252 The interface between the excitation radiation from an illumination source such as laser 22〇6 is directed to dichroic mirror 2208. As shown, the excitation radiation is first reflected by the back surface of substrate 22 20112 59 201106032 as indicated by the solid arrows. The excitation light is then reflected by the dichroic mirror 2208 toward the substrate and the reaction region disposed thereon, such as the reaction region 2204 in Figure 22A. The fluorescent signal emitted from the reaction region can then enter the objective lens 2210 through the dichroic mirror 2208. And entering the remaining portion of the string of optical elements and the detection system as shown in Fig. 22A. By providing the total dichroic mirror element in a direction perpendicular to one of the optical paths as shown in Fig. 22B, instead of 22A is relative to the The tilt of the orientation reduces the amount of optical aberration introduced into the space of the objective lens, and the optical aberration may reduce the image quality on the detection plane or the confocal plane depending on the situation. Time multiplexing On the one hand, multiplexing can be achieved by multiplexing a given system, such as exposing different areas at different times, to assist or replace the other multiplexed solutions described above. The system can include switching between different groups of regions at a relatively low speed, which is similar to a scanning method, such as lighting and/or detecting in different regions at different times, wherein different timings are different for different regions. Not critical. Optionally, and with reference to a portion of the 'analysis time of the present invention, the multi-task is ordered at a sufficient frequency for a particular analysis, and substantially simultaneously acts and/or detects in different regions. From the aspect of the photographic frame capture rate, the detection in different regions is simultaneous, as explained previously. This aspect of the invention is illustrated in Figure 23 in a schematic manner. If not, a first illumination mode is provided on a substrate 2300 that illuminates a first subset 23〇2 of the reaction zone 231〇 at a first time point, such as time t-o. Then, the time t-b is switched to the illumination area 23, and the difference is 60 201106032 t=〇 and t=1 are temporally sufficient subset 2304. For the purposes of the present invention, the proximity is such that the switching frequency is sufficient, whereby the two illumination modes are substantially simultaneous. Although the color display is in the dichotomous mode between (4) and (10), a variety of different illumination modes, such as the present invention, can be illuminated and switched during the desired time period to provide substantially simultaneous illumination of different regions. . For example, random or arbitrary selections or subsets of blocks, columns, portions or regions may be illuminated separately in substantially the same manner. In at least one implementation, the time multiplex system of the present invention illuminates different regions on a substrate using a light switching assembly that selectively and rapidly switches between two or more different optical paths. For example, the illumination path in the first aspect of the analysis system includes a switchable directional mirror located within the optical path to switch the direction of the excitation illumination to a different location on the substrate. In more complex systems, a programmable mirror array that can quickly direct the calibration illumination to different portions of a substrate, such as a digital optical processor (DLp), can be used. Other dynamic switching components, such as a MEms shutter array, a spatial light modulator such as LCDSLM, can be selectively cut off for the optical path of the subset or even individual beamlets. Figure 24 illustrates an example of such a lighting control. As shown, illumination path 2400 includes an excitation radiation source, such as laser 2402. The s-ray laser is directed through a suitable multiplex optical element, such as one or more diffractive optical elements, gratings, etc., such as DOE 2404, to produce a desired illumination mode for one of the multiplexes. The calibration illumination mode is directed to a mirror 2406' that selectively directs a portion of the illumination pattern through the remaining string of optical elements, such as dichroic mirror 2410 and objective lens 2408, to be incident on the substrate 514 61 201106032. Part of it. The fast switching of the mirror results in high frequency illumination for different areas on the substrate 2414 at different times, but is preferably within the frame capture period of the detection system. In the best case, the operating frequency of the switching system exceeds the incident rate of the device in the system, such as the frame capture rate of the camera. In particular, switching at least 1 time, and preferably at least 2 times, in an H-frame capture event, and in some cases, for example, switching at least 3 times, 4 times, 5 times or more more often During the time of the frame, the switching process should be substantially undetectable and unobservable for the detection system. For example, for a still camera with a frame rate such as from 1 〇〇 to 1000 Hz, the switching frequency of the detection system should be at least 100 Hz, 200 Hz, ι Ηζ, 2 〇〇〇 Hz or even higher. As will be appreciated, in some cases, individual beamlet dynamic modulation can be used to adjust the relative intensities of individual beamlets or beamlets to be caused by other aberrations in the optical system, such as vignetting. The variation across the substrate is adjusted. As will be understood, while referring to the different portions of the multiplexed beam of the multiplexed optical component 2404 being transferred to the substrate 2414 in an intermittent manner, in some cases, the switching component may simply redirect the multiplex beam to the substrate 2414. Partial injuries to further enhance multiplex. For example, in some cases, multiplex optical component 2404 can produce an illumination mode that illuminates a subset of the first regions, such as subset 2302 in FIG. The switching function then directs the same mode of calibration illumination to an additional subset of regions, such as region 2304 in Figure 23. Thus, the multiplex optical element can be selectively designed to provide the same function, such as illuminating reaction zones in every other column or row. The switching optics 62 201106032 is then configured to reflect the beam to the reaction zone of the illumination intermediate column or row during half of the period. C. Search activity Although many aspects of the invention are directed towards increasing the total number of reaction zones that undergo illumination and/or detection for the analytical reaction, in some cases, a large number of reaction zones may be initially examined, followed by only active An effective multiplex is achieved by performing a subsequent illumination and/or detection of a subset of such regions showing signs of reaction to be explored. Thus, in yet another aspect, the increased multiplex is applied only to the active area on a substrate. In fact, the method examines the large reaction area, but only continues to analyze a small subset. Thus, while an initial review is performed for a high multiplex, the final analysis is performed on a subset of the reaction regions that may not even require a significantly smaller multiplex factor. The resulting analysis effectively increases multiplexing, which means that the level of analytical processing in the relevant areas is high and there is no need to maintain high multiplex analysis throughout the analysis period. As a result, the required energy input may be lower than the direct high multi-work mode, with gain in signal noise ratio and the like. Figure 25 graphically illustrates an overview of the previously mentioned methods. As shown, 2502 - substrate 2500 with a large number of potential reaction regions is first extensively reviewed to identify active reaction regions (as indicated by solid circles 25〇4). The broad illumination effect may be in the form of a unified flood illumination of the entire substrate or a significant portion thereof, or may be in the form of a scan analysis for different regions to identify those exhibiting actives. Optionally, a calibration illumination can be similarly used to identify the active region 2504. Once identified, the optical system is then configured to illuminate only those regions exhibiting activity, causing only illumination and thus monitoring of signals from such regions (as indicated by the dashed line 63 201106032 circle 2506). The selective illumination material (iv) a plurality of different optical systems or components such as 'as with the time multiplexed illumination method described above, can quickly configure the programmable mirror array' to illuminate only the exact region selected on a particular substrate. Similarly, an LCD mask having an addressable pixel used in a conventional flat panel LCD display can be used to selectively illuminate a desired area on a substrate. The components can be configured as described with respect to mirror 2 in Figure 24 to selectively orient the beamlets that are directed to the base-dependent region. In particular, by providing an LCD reticle, individual pixels can be selectively addressed such that they are turned on or off for excitation illumination, such as the transmission of a small beam, thereby controlling the beamlets that are ultimately incident on the substrate. The number and mode. In addition to providing controllable reticle illumination in different areas on the substrate, the above methods can also be used to adjust the illumination intensity of different areas on a substrate. In particular, by modulating light passing through different mask elements, the intensity of light received by the substrate can be modulated. The above modulation is particularly useful for the inhomogeneity of the calibration illumination caused by other optical components, such as the inhomogeneity caused by variations in multiplexed optical components such as DOE. In particular, a gray scale mask can be fabricated or programmed in the case of a programmable spatial light modulator to adjust for any predetermined inhomogeneity/consistency between the nominal illumination effects of the different illumination regions. In particular, one of the illumination profiles of a particular optical path can be taken to take samples, including multiplexed optical components, and a spatial light 5-variant or reticle is configured based on the mode to properly correct for deviations, such as reducing brighter illumination. The strength of the point. D. Enhanced multiplexed illumination effect 64 201106032 In other aspects, the present invention provides enhanced multiplex illumination effects using a plurality of illumination sources in combination with one or more diffractive elements to illuminate a large number of discrete reaction zones. In such cases, two, three, four, five, ten or more laser beams can be directed through one or more diffractive optical elements to create a plurality of illumination points on a substrate. When, for example, a diffractive optical element is used to provide a discrete beam of light to illuminate a large number of discrete regions on a substrate, to ensure adequate power delivery to a large number of illumination regions, it is typically desirable to increase the power applied to the system. In the case of ultra high multiplex systems, the individual lighting sources used to carry out this are not commercially viable due to cost and availability. For example, in a particular exemplary application, a single illumination source beam is split into small beams that provide about 5 microwatts per square micrometer. To achieve this same illumination power for 80,000 discrete points, it means that a single illumination beam will have about 500 megawatts. In addition to laser issues, the diffractive optical elements typically produce a beam pattern that has reasonable beam uniformity over a relatively small field of view. However, when it is desired to expand the field of view, the non-uniformity of the illumination pattern will be excessive for some applications. Thus, a significant change in illumination intensity across illumination points would be expected when the multiplexed illumination scale, for example, expands by one or more. Thus, in one aspect, the present invention provides a plurality of illumination sources and/or source beams directed through one or more diffractive elements to provide an easily accessible, low power illumination source and a high cross-illumination field of view uniformity. Ultra-high multiplex lighting effect. In a first aspect, a plurality of illumination beams are directed through a single diffractive element at different angles to provide an output illumination mode that reflects the plurality of beams and an angular variation in the end of the beam. This is illustrated graphically in Figure 26. As shown, the plurality of illumination beams, shown by solid line 2602 and dashed line 26〇4, are directed to diffractive optical element 26〇6 at different angles as indicated by angle 2608. The pattern produced by the illumination "small beam" 2610 emitted by the DOE of each of the originating beams is directed to the substrate 2612 in its own mode (as illustrated by the centroids and hollow dots on the substrate 2612), each of which The mode is offset by a function of one of the angular differences between the two ends of the beam. In addition to using multiple illumination source beams, the present invention contemplates the use of multiple diffractive elements, wherein each diffractive element receives a subset of the originating illumination beams to produce a correlation mode. ; the higher multiplex mode emitted by the & self-single-diffractive element may provide excessive variation in the entire larger field of view. 'The illumination mode may be provided using a subset of the -specific substrate-regions. A plurality of diffractive elements, whereby the presence of the (four) cents is kept in a relatively small field of view' and thus does not exceed the range for the desired application. An example of such a system is illustrated in Figure 27A. In particular, as shown, a multiplexed diffractive optical element 27A6 is provided which includes a single integrated component or a plurality of connected diffractive optical elements 27()4. A plurality of originating beams (e.g., emitted from a plurality of illumination sources such as a solid line, a short dashed line, and a long dashed line) are directed to the multiplexed DOE 2706, wherein each beam is directed at an angle that is slightly offset from the other beams. DOE. As shown, a polyhedron, waveguide array, fiber bundle or other optical component can be included to redirect each beam to its appropriate hall assembly. In addition, the individual coffee components in the array can be angularly skewed to provide the best direction for the emitted beamlets to pass through the remaining string of optical elements. 66 201106032 The beam pattern produced by each of the DOE elements 2704 within the self-integrating DOE 2706 is then transmitted through an array of optical elements (as shown by lenses 2708, 2710 and objective lens 2712) that focus the beam onto a substrate 2714. As shown, the different beams are focused' to provide their illumination modes to different subsets of the substrate. For example, as shown in the schematic development of the beam, the interlacing of the illumination modes from each component 2704 can be used to provide multiple offsets, but interleaved with the illumination pattern on substrate 2714, as shown in Figure 26. Optionally, different beamlet patterns can be directed to completely different regions on the substrate, such as quadrants, to illuminate individual substrate regions. Figure 27 illustrates several d〇e component configurations for achieving high multiplexing, including five DOE array components (a) and (d), seven array components (b) and (e), and nine DOE arrays. Components (c) and (1). Depending on the level of multiplex and the desired lighting mode, other configurations are also possible. In a preferred aspect, each DOE component in an array will be configured to have a different skew angle, except that the incident beams are evenly divided into a large number of beamlets in the illumination mode in angular space. For example, with respect to the nine-sided DOE assembly illustrated in Figure 27B, each of the DOE components or faces in the array can provide a small beam of 100x100 from a single incident beam. They can have a uniform spacing such as a space between 乂 and ey. 1 milliradian (mrad). The skew angle of the first DOE (#1) is, for example, 5 milliradians in one direction, and the second DOE (#2) will be skewed by 5 milliradians in both θχ and one angular space, the third DOE (#3) ) will be skewed at 0y angle space by 5 milliradians and so on. As will be understood and as mentioned above, each D〇E can be used to convert - or multiple illumination beams into a beamlet mode of the steering substrate. 67 201106032 E. The multiplex detection function is similar to the multiplex mode of applying the illumination side of the analysis system, and assists or as an alternative to the methods, the present invention also provides enhanced multiplex on the collection side of the system, such as The optical path of the signal transmitted from the reaction area on the substrate is collected and detected. In particular, at least one limitation on the potential of ultra high multiplex systems is the ability to measure signals transmitted, for example, from larger and larger discrete areas on a substrate. As will be appreciated, the actual limits expected for signal detection from different regions on a substrate at any one time will be limited by the number of elements or detector elements in a particular detection system. In particular, a particular detector pixel will only detect the number ' and in the absence of other considerations' incident on the signal from one source and from another source or combination source will not be discernible. However, as will be understood that the actual limitation of each pixel with a signal is that it is not completely feasible in itself. Because of the signal detection on multiple pixels, a large amount of different information, such as spectral information, array position, etc., is provided (see, for example, 2007). US Patent Application Publication No. -0206187, International Patent Application Publication No. WO2007/095119, and U.S. Patent Application Serial No. 12/134,186, filed on Jun. 5, 2008, the entire disclosure of each of All of the objects are hereby incorporated by reference in its entirety into this application. Similarly, separating the signal components on the array helps to avoid signal cross-contamination. In view of these and other considerations, it would be advantageous to optimize the efficient use of the detector array area in the multiplex mode. In a first example, a signal transmitted from an array of one of the reaction zones on a substrate can be directed to a different array of detector arrays or even different detector arrays to best detect Measure signals from highly multiplexed substrates. In a related example, different signal components from individual signal sources can be directed to different detectors. Optionally or additionally, just as the time switching effect of the illumination, the signals transmitted from different regions of a substrate may be separated in time, but in other cases directed at the same, overlapping, adjacent to a substrate at different times. Or discrete parts. Again, by applying the switching action at a frequency that exceeds and preferably significantly exceeds the slowest signal period, the time separation will provide seamless detection of the desired signal event. In addition, by synchronizing the signal analysis process with the switching action, a particular location on the substrate can be easily assigned to a signal event, even when the signals are incident on the same location of a detector array. As will be understood, the same or similar components can be used for optical switching of the signal direction, as discussed in the Switching Actions section of the Calibration Lighting Mode. In addition, it will be appreciated that the previously discussed LCD reticle can be used similarly for the concentrating path to selectively turn the concentrating path on and off for signals from discrete reactive regions or subsets of reactive regions. By using the "work sharing" detector in the detection area between different signal sources, although at different points in time, the number of sources detected by a single detector or a group of detectors can be multiplied by more than unused. One method of time multiplexing. In a related aspect and as mentioned above, an individual substrate comprising a plurality of discrete reaction regions can be divided into a plurality of different sub-FOVs, each of which can be directed to a different detector to Compliant with high multiplex 69 201106032 substrate. In order to monitor these sub-fields efficiently and simultaneously, it is preferable to maintain a single optical element string that achieves the monitoring method. Thus, in one aspect, the invention provides an optical system that illuminates one of a plurality of reaction zones on a substrate, but directs signals from each of the plurality of subsets of the reaction zone to different detectors. An example of an optical system for collecting fluorescent signals from different regions of a substrate and transmitting them to one of the different detectors is illustrated graphically in Figure 28. As shown, the system 2800 includes a substrate 2802 having a plurality of discrete reaction zones or regions to be explored thereon or therein. The substrate 2802, and particularly the region for analysis, is disposed on the front focal plane of the objective lens 2804. The objective lens 2804 and the barrel 2806, as shown, image the region of interest to be located in the posterior focal plane of the barrel 2806 and near the intermediate image plane of the reflective mask 2808. The reflective mask 2808 splits the image and reflects the subset toward the detector 2810 and a portion toward the detector 2812. The reflection point of the reflective reticle is typically provided in the focal plane, thereby not causing a loss of fidelity. Also shown is that each of the detection paths includes spectrally separated optical elements such as focusing lenses 2814 and 2816 and 2818 and 2820, respectively, and dispersive optical elements for color separation, such as 稜鏡2822 and 2824, respectively. Although it is described in the form of dividing the image into two separately detected images, 'the configurable reflector or other imaging optics will be understood to divide the image into more image components, such as 2, 3, 4, 8 , 16 or more discrete image components, each of which can be directed to a different detector. As mentioned previously, the imaging can be done in several ways. For example, in a simple aspect, the reflective reticle 2808 can comprise, for example, a wind turbine mirror having a separate deflection 70 201106032 = wherein each surface reflects one of the images in a different detection path. Optionally, a micro- or micro-mirror array is used, such as as a reverse hood 28G8' to direct images of each sub-field to different detection paths having an array of polyhedral surfaces that are projected in a desired direction y. . As will be understood, the subject can be configured as in the present invention to divide the image into a plurality of discrete constituent images. In the -related system, the different signal components from different signal sources on the substrate can be differentially directed to different controllers. In particular, in the n(4) secret shown in Fig. 22, a plurality of signal components are spatially separated by the dispersive optical element 2216, and imaged on the detector 2220. In the case of ultra-high multiplexed array substrates, the ability to spatially separate images of different signal components becomes more difficult when different signal sources are closely placed on the array, as there are not enough detector areas available. The substantially overlapping portion of the contained component 'and its etc. that begin to map to the detector array is broken. By directing different signal components to different detectors, a denser source of signals can be imaged on the substrate. It is illustrated graphically in Figure 29A. In particular, as shown in schematic image 2902, four signal components, such as spectrally unique and separated fluorescent signal images 2904-2910, are imaged on a portion of a debt detector array. By directing a subset of the signal components, such as signals 29〇4/ 2906 and 2908/2910, to different detectors, it is possible to efficiently image nearly twice the number of signal sources such as ZMW without worrying about signal overlap. The number of detectors, such as the number of signal sources that can be imaged by the two detectors, provides the ability to image up to two more sources. In the preferred case, however, the additional spacing required to distinguish adjacent sources may be 71 201106032 such that there is a large separation between signal components from different sources. Therefore, the number of imageable sources may not completely follow the number of detectors. A pictorial illustration of the optical system for performing the above-described detection multiplexing is provided in Fig. 29B. In the system shown, the excitation optics of the system are arranged similarly to the system shown in Figure 22, such as having a two-color galvanometer between the objective lens and the substrate. In particular, as shown, system-wide 2950 includes one or more excitation sources, such as lasers 2952 and 2954. As with all such systems, the number of excitation sources can vary depending on the needs of the particular application, such as the excitation wavelength of the different fluorophores used in the system, and the wavelength of the laser used. In the illustrated exemplary system, the dichroic mirror 2956 transmits light and reflection from the laser 2954 by directing the two excitation sources (illumination sources) to the dichroic mirror 2956 and combining them in the same optical path. The light beam from the laser 2952 is thereby collinear. Again, in the system shown, the excitation beam is directed to an additional dichroic mirror 2958 that acts to reflect the excitation light toward the substrate 2960 while transmitting fluorescent signals having different wavelengths to the collection objective 2962. As shown, the signal is first reflected from the surface of another component, such as a separate mirror in the string of optical elements or the back surface of the substrate, as described above in FIG. The spectrally separated signal component from substrate 2960 is emitted as a fluorescently labeled different reagent and then passed through dichroic mirror 2958 and objective lens 2962. The signal component is then separated into spectrally separated signal components by a dispersive optical element such as a dovetail 2964' (as indicated by the solid and dashed arrows from the self-twisting 2964). The signal component is then directed to a subset of the dichroic mirror 2966' which reflects the signal component and transmits another set of 72 201106032 signal components. Each of the different subsets of signal components is then imaged on detector 2968 or 2970. As indicated above, although the display has two detectors, it will be appreciated that additional detectors can be used to integrate other sub-images of the signal component, such as via the use of additional dichroic mirrors, each having a different orientation. The four signal components of the detector. F. Glass Filled Object Area In one aspect, the present invention provides an improved optical system having a glass filled optical space. As described herein, an optical element system for analyzing, for example, an array of reaction regions having a fluorescent reagent for analyzing a chemical reaction, generally has an illumination optical element incident on the reaction region, and detecting a reaction occurring in the reaction region. Light collecting optics. In some cases, a dichroic mirror element that acts as a mirror for light, such as illumination wavelength, but transmits light of the emission wavelength, can be used to control the illumination action and the optical path of the collection system. In some cases, the use of a self-standing dichroic mirror can cause optical aberrations and loss. A shaped optical block is incorporated in the present invention having an embedded dichroic mirror element between the illumination optics and the sample and between the collection optics and the sample. The refractive index of the optical element block will typically exceed the refractive index of air. By having a higher refractive index, a larger portion of the emitted light can be collected by a detecting optical element having a specific aperture. In addition, by using a dichroic mirror embedded in the optical block, the deflection angle and the cone angle of the light incident on the block are reduced, and in some cases, the spectral performance of the dichroic mirror and the sensitivity of the system are increased. . An exemplary implementation of a system comprising one of the shaped optical element blocks 73 201106032 is shown in Figure 30. Illumination (excitation) optics 3030 directs the illumination trousers through face 3001 into optical block 3A. In the illustrated embodiment, the surface 3002 is coated with a reflective material to enhance the internal reflection effect to reflect the illumination light. The illumination light is then reflected from the embedded dichroic mirror element 3010 and passed through the face 3〇〇2 into a substrate 3020 that can include a plurality of reaction zones. The reaction of the reaction zone can be measured by detecting a fluorescent event. The emitted light 3045, such as fluorescent light from the reaction zone, enters the block via a surface such as 耵 and is transmitted through the dichroic mirror element 3〇1〇. In the illustrated embodiment, substrate 3020 is optically coupled to optical block 3000 to minimize reflection losses and aberrations. The emitted light then exits the shaped optical block via face 3〇〇3 and into collecting optical element 3040. While the third diagram shows the reflected illumination light and the transmitted light, in some embodiments, the embedded gas octagonal mirror will transmit illumination light and reflect the emitted light. The face of the shaped optical element block through which the illumination light and the collected light are transmitted may be planar, and may be at an angle that maximizes optical performance. For example, the faces may be fabricated perpendicular to the string of associated optical elements. In this way, the chief ray can act as a thick, non-tilted plate for the purpose of correcting aberrations. In some embodiments, one or more sides of the shaped optical element block can be curved to provide a lens function by redirecting light through the face. The faces can be curved in a concave or convex manner as desired to redirect the illumination or the emitted light. It is generally expected that the optical component block will contain a significant portion of the optical path length of the system. That is, the optical path distance through the optical element block will be at least 5 G/〇, at least 60%, at least 7 Q of the total distance between the illumination optical element and the substrate or between the collection optical element and the substrate. %, at least 8Q%, at least 9%, at least 95%, at least 98%, at least 99% or higher. In some cases, the illumination optics, substrate, filament optics, or any combination of the above are combined with the (4) optical component block having a refractive index localized to the air. For example, a fluid or an oil-yield having a refractive index closely matched with (4) an optical block or another component can be used, so that the (iv) component is light-contracted. The dichroic mirror 7 is embedded in the shaped optical element block, and the dichroic mirror 7L is shown in the block (4) block optical system, and there is usually little or no _ between the dichroic mirror element and the optical block. . In some cases, the dichroic mirror can be molded or (d) into the shaped optical component block. In other cases, the chromonic mirror element can be coupled to the optical block of the portion, such as a fluid, oil or polymeric material. The x-shaped dry 7G block is made of a material that is transparent at the wavelength to be explored. This block can for example be made of a vitreous oxide material. The gas block may, for example, comprise a dioxotomy. Additives to adjust the refraction of the block (4) its quality. In some cases, the Wei block has a wavelength of about U and about 5. The refractive index between G can be needed by the merchant. The refractive index can be, for example, at or about 1. 3 and about 25 gates' = mouth to about Μ and 2. Between 0. In some cases, the high refractive index _ = desired 'in some cases, the higher refractive index material will tend to have a high self-light level. Therefore, we have found that materials with a radiance are particularly suitable. This block has a low level of spontaneous glory in the analysis used, which is usually desirable. The dry land will be used, for example, at about 4. . Nano to about 7. . Nano Fan Gu: Can 2: 75 201106032 can use infrared light and ultraviolet light. The wavelength of the illumination light is usually different from the wavelength of the emitted light. III. EXAMPLES Example 1: Parabolic mirror substrate A substrate having a zero mode waveguide disposed through a metal layer was deposited which was deposited on a parabolic body defined in a glass substrate. These devices were fabricated in accordance with the method described in Figure 10 and the accompanying description, except that subsequent substrate planarization (steps V-VII) was not performed. A hole through the metal layer for defining the zero mode waveguide core is fabricated using a focused ion beam (FIB etching method) to define a core having a diameter of about 12 nanometers. Figure 31A shows the resulting construction of the self-constructed metal layer side image using scanning electron microscopy (SEM). An open-mode zero mode waveguide core located at the center of the center of the construction is visible. Also provided is a comparison substrate having no parabolic or other reflective configuration as shown in Fig. 31B having a zero mode waveguide having a cross-sectional dimension approximately the same in a planar metal layer disposed on a planar glass substrate. The test reflection construct operates on the transmission of light to or from a zero mode waveguide core. A fluorescent dye is deposited on the open side of the two different waveguide structures, and both illuminate with the same excitation illumination and detect the emitted fluorescent light. Based on the average fluorescence intensity of the zero-mode waveguide from one of the two comparison substrates, it is found that the waveguide provided on the reflective structure provides a fluorescent signal six times higher than that of the conventional ZMW, and shows the whole system of light collection. Increased efficiency. Case 2: Theoretical Simulation of Conical Mirror Substrate 76 201106032 The various component molding configurations described in Figures 3 and 3, respectively, are used. For example, with regard to the straight conical configuration illustrated in Figure 32, the dimensions are set as follows: dl = 1. 25 microns; d2 = 5 microns and h = 4. 69 microns. This mode assumes an objective lens for collecting light emitted from the substrate/reflector assembly, having a numerical aperture of 〇5 and a maximum concentrating angle of +/- 20 degrees with respect to the optical axis, thereby providing from 70 to The angle of collection of 110 degrees with respect to the bottom surface of the substrate. Based on the conical pattern shown in Figure 32, the angle of the light reflected from the cone is from 43. 58 degrees (0〇 to 1〇5. 52 degrees (0&). For the two segmented conical reflectors shown in Figure 33, the dimensions are set to 疋. Dl-1. 25 microns; d2 = 3 microns; d3 = 5 microns; hl = 1 micron; and h2 = 3. 69 microns. In this case, the angle of the light reflected and emitted by the reflector is between 82. 3 7 degrees (0tr) to 116. The range of 06 degrees (0br). For the above two types of structures, the photon collection efficiency of an objective lens using a light collecting objective lens having a numerical aperture of 0 95 is estimated to be about 70%, as compared with a substrate not including a reflector assembly, as shown in FIG. 31B. The collection efficiency of a zero mode waveguide disposed on a transparent substrate layer is about 42%. This analysis predicts improved optical performance due to the inclusion of micromirrors, but the analysis is essentially a ray tracing analysis that does not include diffraction or wave effects and thus does not provide a complete picture of the desired performance. Analysis by a vector tool has also been performed which confirms the optical enhancement from the micromirror construction of the present invention. Example 3: Fabrication of an array of nano-reactive regions on a micromirror structure using a sacrificial column A 500 nm polymorph was deposited on the molten vermiculite by LPCVD at 350 °C.

Using a 248 nm stepper and a Cultura (Centura) MXP etching machine for mirror etching. The array is then annealed at 6 以 to reduce spontaneous fluorescence and degassing organic contaminants, then Aluminium evaporation and de-covering (removal of polysilicon) in a wet solution (3 01 3 /. hydrogen peroxide) without attacking the aluminum on the mirror surface. SEM micrograph shown in Figure 34 The figure shows a portion of an array of reaction zones with associated micromirrors. Figure 35 shows a single micromirror configuration with a reaction zone at the top. Figure 36 shows a nanoscale reaction zone at the top of a micromirror configuration. The fourth example: using a sacrificial layer and a hard coat layer to fabricate a nano-scale reaction zone, sequentially coating a melting layer with a polysilicon layer and a hard mask layer such as hafnium oxide or tantalum nitride. a stone substrate. The photolithography method is used to define a ring-shaped array having a diameter of about 380 nm, and the hard mask is etched to produce a hard mask disk having a '''s spoon shape. The mysterious 4 size is used. Then 3% is used. Controlled over-etching of one of aqueous hydrogen peroxide, The layer is engraved to create a pillar of about 2 nanometers in diameter below the hard mask disk. The etching rate can be controlled by adjusting the conditions and materials. For example, when using an undoped polysilicon The etching rate of 3〇% aqueous hydrogen peroxide at 5〇t is about 460 nm/min; and when doped polysilicon is used, the etching rate of 3〇% aqueous hydrogen peroxide at room temperature is about 200 nm/min. Aluminium having a thickness of about 1 nm was sputtered on the surface. Heating was used to about 5 Torr. (: The above aqueous hydrogen peroxide was removed, and the polycrystalline column was removed. SEM micrograph confirmed A hole having a diameter ranging from 200 nm to 250 nm is produced in an aluminum film on the molten vermiculite. Example 5: Conical micromirror structure produced on a molten vermiculite substrate Fig. 37 shows Scanning electron micrograph of an exemplary cone 78 201106032 micromirror structure formed on a molten vermiculite substrate. The top diameter of the conical structure of Fig. 37(A) was measured to be about 2·40 μm and the bottom The diameter is about 4. 90 microns. The top diameter of the conical configuration of Figure 37(B) was measured to be approximately 1. 68 microns, and the bottom diameter is about 4. 18 microns. Other micromirror configurations (not shown) made on the molten vermiculite substrate have a top diameter/bottom diameter/height determined to be: 1. 30/3. 96/3. 45 microns, 1. 49/4. 17/3. 184 ruined rice, 1. 68/4. 34/3. 30 microns, 2. 79/5. 27/3. 36 microns, 2. 55/5. 60/3. 23 microns, 2. 66/5. 38/ 3. 72 microns. Figure 37 (C) shows a conical micromirror configuration coated with aluminum having a zero mode waveguide aperture through the top of the micromirror construction. Figures 38(A) to (E) show SEM micrographs of a conical configuration produced on a molten vermiculite substrate. The configuration of Fig. 38 corresponds to the configuration after, for example, the step (II) of the method described in Fig. 15. Figure 39 shows an SEM micrograph of a section of a micromirror having an aperture at the top. The structure shown in Fig. 39 corresponds to a configuration formed after the step (VIII) of the method described in Fig. 15. In this configuration, the micromirror structure is surrounded by a planarization layer such as a spin-on glass. Figure 40 shows an array of micromirror structures that are formed on a dazzling stone substrate and have apertures on top of each other. Case 6: Gain measurement of conical micromirror construction Measurements were made to determine the amount of gain produced using a micromirror configuration coupled to a zero mode waveguide. A substrate was prepared from molten vermiculite (FuSi) having a ZMW structure on top of the micromirror and a comparable ZMW structure on the planar portion of the substrate. Figure 41 shows a schematic illustration of the experimental setup in which the light system 79 201106032 is transmitted through the ZMW configuration on the substrate. Light transmitted through the ZMW structure is collected by an optical component string and detected on a CCD camera. The optical detection system has a numerical aperture of 0. 5. Table 1 lists representative measurements of the ZMW structure from the flat area of the substrate and the intensity detected from the ZMW structure on top of the micromirror structure. Calculate the gain from these measurements to be approximately 5. 9. It will be appreciated that the measured gain will depend on the numerical aperture of the collection optics.

An array. Contact lithography with resist reflow and 3 micron deep reactive ion etching (RIE) 80 201106032 followed by annealing with 4 〇〇 °C by sputtering silver smoothing to form micromirrors in the substrate structure. A 200 nm aluminum layer was then applied to the surface. The aluminum layer was patterned and etched to create a 120 nm diameter ZMW at the center of the top of the adjacent micromirror configuration. Excessive etching is used whereby the ZMW aperture extends into the molten vermiculite (FuSi) substrate by about 50 nm. The top diameter of a representative micromirror structure was determined to be about 3. 4 microns and the bottom diameter is about 6. 8 microns. For example, Eid et al., in the journal Science, No. 323, pp. 133-138 (2009), is similar to Lundquist et al. in the journal "Optics Letters", No. 33, page 1026 (2008). The numerical aperture is 0. One of the three optical systems performs a single molecule sequencing reaction.

The dark spikes in Figure 42 correspond to 647G, while the lighter spikes correspond to 555c, exhibiting nucleic acid sequencing using a zero-mode waveguide with a micromirror array. As described by Eid et al., four-color sequencing can be performed in a similar manner.
