Description
本發明係關於一種半導體裝置。The present invention relates to a semiconductor device.
吾人已知光學微影在193 nm光波長和1.35數值孔徑(NA, numerical aperture)浸沒系統已達到其能力的終點。這個設備的最小直線解析能力係大約40 nm以及大約80 nm的特徵部間節距。低於約80 nm的特徵部間節距需求,則需要一給定晶片階層內一給定結構型態的多重圖案化步驟。此外,隨著將微影推向其解析度的極限,線端解析度變得更具挑戰性。在半導體裝置佈局中,於32 nm關鍵尺寸之典型金屬線節距係大約100 nm。為了達到特徵部縮放(feature scaling)的成本效益,期望有0.7至0.75的縮放因數(scaling factor)。為達到22 nm關鍵尺寸之約0.75的縮放因數,將需要約75 nm的金屬線節距,這節距低於目前單一曝光微影系統和技術的能力。在此背景下產生本發明。It is known that optical lithography has reached the end of its ability at 193 nm wavelength and 1.35 numerical aperture (NA) immersion systems. The minimum linear resolution capability of this device is approximately 40 nm and an inter-feature pitch of approximately 80 nm. An inter-feature pitch requirement of less than about 80 nm requires a multiple patterning step for a given structural pattern within a given wafer hierarchy. In addition, as the lithography pushes to the limit of its resolution, line-end resolution becomes more challenging. In a semiconductor device layout, a typical metal line pitch of a critical dimension of 32 nm is approximately 100 nm. In order to achieve the cost-effectiveness of feature scaling, a scaling factor of 0.7 to 0.75 is desired. To achieve a scaling factor of approximately 0.75 for a 22 nm critical dimension, a wire pitch of approximately 75 nm will be required, which is lower than current single exposure lithography systems and techniques. The present invention has been produced in this context.

「鰭式場效電晶體」係由垂直的矽島(即鰭部)所建構的電晶體。鰭式場效電晶體亦可稱作三閘極電晶體。此處所使用之術語「鰭式場效電晶體」係關於包含自下層基板向上突出之擴散結構的任何電晶體構造。圖1A及1B顯示根據本發明若干實施例之鰭式場效電晶體100的例示佈局視圖。鰭式場效電晶體100係由擴散鰭部102和閘極電極層104所構成。擴散鰭部102由基板105垂直向上突出,如圖1B所顯示。閘極氧化物層106係配置於擴散鰭部102和閘極電極層104之間。擴散鰭部102可加以摻雜,以形成p型電晶體或n型電晶體。覆蓋擴散鰭部102之閘極電極層104的部分,形成鰭式場效電晶體100的閘極電極。因此,相對於在非鰭式場效電晶體中由一側提供通道的控制,鰭式場效電晶體100的閘極電極可存在於擴散鰭部102的三個以上側邊,藉此提供由三個以上側邊之鰭式場效電晶體通道的控制。此外,在若干實施例中,鰭式場效電晶體形成為「環繞式」電晶體,其中閘極氧化物層106和閘極電極層104亦在擴散鰭部102下方延伸。"Fin field effect transistor" is a transistor constructed by vertical islands (ie, fins). A fin field effect transistor can also be referred to as a three gate transistor. The term "Fin Field Effect Transistor" as used herein relates to any transistor configuration comprising a diffusion structure that protrudes upward from the underlying substrate. 1A and 1B show an exemplary layout view of a fin field effect transistor 100 in accordance with several embodiments of the present invention. The fin field effect transistor 100 is composed of a diffusion fin portion 102 and a gate electrode layer 104. The diffusion fins 102 protrude vertically upward from the substrate 105 as shown in FIG. 1B. The gate oxide layer 106 is disposed between the diffusion fin portion 102 and the gate electrode layer 104. The diffusion fins 102 can be doped to form a p-type transistor or an n-type transistor. A portion of the gate electrode layer 104 of the diffusion fin 102 is covered to form a gate electrode of the FinFET 100. Therefore, the gate electrode of the FinFET 100 may exist on more than three sides of the diffusion fin 102 with respect to the control of providing the channel by one side in the non-fin field effect transistor, thereby providing three Control of the fin field effect transistor channel on the above side. Moreover, in some embodiments, the fin field effect transistor is formed as a "wraparound" transistor, with the gate oxide layer 106 and the gate electrode layer 104 also extending below the diffusion fins 102.
應理解的是,在圖1A及1B中所描繪的例示鰭式場效電晶體100,係以例示為目的而提供,不代表對此處所參照之鰭式場效電晶體的設計及/或製造方式的任何限制。具體而言,在若干實施例中,擴散鰭部(如102)可形成為不同材料的成層,其包含但不限定於Si(矽)、SiGe(矽鍺)、Ge(鍺)、InP(磷化銦)、CNT(奈米碳管)、SiNT(矽奈米管)、或其任何組合。閘極氧化物層106可由許多不同類型的介電材料加以形成。舉例來說,在若干實施例中,閘極氧化物層106可形成為在一二氧化矽層上的一鉿氧化物層。在其他實施例中,閘極氧化物層106可由一種以上其他介電材料加以形成。在若干實施例中,閘極電極層104可由任何數量之導電材料加以形成。舉例來說,在若干實施例中,閘極電極層104可形成為由多晶矽所覆蓋之一TiN(鈦氮化物)膜或一TaN(鉭氮化物)膜。然而,應理解的是,在其他實施例中,閘極電極層104可由其他材料所形成。It should be understood that the exemplary fin field effect transistor 100 depicted in FIGS. 1A and 1B is provided for illustrative purposes and does not represent a design and/or fabrication of the fin field effect transistor referenced herein. Any restrictions. In particular, in several embodiments, the diffusion fins (eg, 102) may be formed as layers of different materials including, but not limited to, Si (germanium), SiGe (germanium), Ge (germanium), InP (phosphorus) Indium), CNT (nanocarbon tube), SiNT (tanometer tube), or any combination thereof. The gate oxide layer 106 can be formed from a number of different types of dielectric materials. For example, in some embodiments, the gate oxide layer 106 can be formed as a tantalum oxide layer on a layer of germanium dioxide. In other embodiments, the gate oxide layer 106 can be formed from more than one other dielectric material. In several embodiments, the gate electrode layer 104 can be formed from any number of electrically conductive materials. For example, in some embodiments, the gate electrode layer 104 can be formed as a TiN (titanium nitride) film or a TaN (yttrium nitride) film covered by polysilicon. However, it should be understood that in other embodiments, the gate electrode layer 104 may be formed of other materials.
此外,雖然將圖1B的例示擴散鰭部102在該垂直剖面視圖A-A中顯示為具有相對於基板105的實質上垂直突出矩形結構,應理解的是,在半導體晶片上於「製造後(as-fabricated)」狀態的擴散鰭部102可能具有或可能不具有相對於基板105的實質上垂直突出矩形結構。舉例來說,在若干實施例中,於其「製造後(as-fabricated)」狀態的擴散鰭部102在垂直剖面視圖A-A中可能具有更為三角形或角錐形的形狀。圖1C顯示鰭式場效電晶體100的變化,其中在垂直剖面視圖A-A中擴散鰭部102係更為角錐形。如圖1C所描繪,在若干實施例中,自基板105向上延伸的擴散鰭部102的側邊,可能以相對於基板105的一個角度自基板向上延伸,以致不垂直於基板105。此外,應理解的是,基板105與自基板105向上延伸之擴散鰭部102側邊之間的此非垂直關係,可能係經設計或者可能係製造的結果。In addition, although the exemplary diffusion fin 102 of FIG. 1B is shown in the vertical cross-sectional view AA as having a substantially vertically protruding rectangular structure with respect to the substrate 105, it should be understood that on the semiconductor wafer after "manufacturing (as- The diffusion fins 102 in the fabricated state may or may not have a substantially vertically protruding rectangular structure relative to the substrate 105. For example, in some embodiments, the diffusion fins 102 in their "as-fabricated" state may have a more triangular or pyramidal shape in the vertical cross-sectional view A-A. 1C shows a variation of the fin field effect transistor 100 in which the diffusion fins 102 are more pyramidal in the vertical cross-sectional view A-A. As depicted in FIG. 1C, in some embodiments, the sides of the diffusion fins 102 that extend upwardly from the substrate 105 may extend upwardly from the substrate at an angle relative to the substrate 105 such that they are not perpendicular to the substrate 105. Moreover, it should be understood that this non-perpendicular relationship between the substrate 105 and the sides of the diffusion fins 102 extending upward from the substrate 105 may be the result of design or possible fabrication.
此外,在若干實施例中,在基板105上方擴散鰭部102的垂直突出距離,在半導體晶片的一個區域範圍內係實質上相等。然而,在其他實施例中,可將若干擴散鰭部102設計成和製造成在半導體晶片的一或多個區域的範圍內於基板105上方具有多個不同的垂直突出距離。因為鰭式場效電晶體100的通道面積係基板105上方擴散鰭部102垂直突出距離的函數,在基板105上方擴散鰭部102垂直突出距離的此變化可用以調整選定鰭式場效電晶體100相對半導體晶片上其他者的驅動強度。在一個範例中,在擴散鰭部102高度的選擇性變化可藉由在製造期間選擇性蝕刻/過蝕刻擴散鰭部102結構而加以提供。Moreover, in several embodiments, the vertical protrusion distance of the diffusion fins 102 above the substrate 105 is substantially equal over a range of regions of the semiconductor wafer. However, in other embodiments, the plurality of diffusion fins 102 can be designed and fabricated to have a plurality of different vertical protrusion distances above the substrate 105 over a range of one or more regions of the semiconductor wafer. Because the channel area of the fin field effect transistor 100 is a function of the vertical protrusion distance of the diffusion fins 102 above the substrate 105, this variation of the vertical protrusion distance of the diffusion fins 102 above the substrate 105 can be used to adjust the selected fin field effect transistor 100 relative to the semiconductor. The drive strength of the other on the wafer. In one example, the selective change in height of the diffusion fins 102 can be provided by selectively etching/over etching the diffusion fins 102 structure during fabrication.
圖1D顯示根據本發明若干實施例之具有數個鰭式場效電晶體100形成於其上的基板105的簡化垂直剖面圖。在鰭式場效電晶體100的製造期間,形成一系列核心部107,以促進該等核心部107每一者的側間隔部109的形成。側間隔部109係用以作為遮罩特徵以促進下方鰭式場效電晶體100的形成。應理解的是,核心部107、側間隔部109、及鰭式場效電晶體100係以平行方式縱向延伸,即如圖1D所示之進入頁面方向延伸。應理解的是,核心部107和側間隔部109最終被移除,而不存在於最終製造後(as-fabricated)半導體晶片/裝置之中。鰭式場效電晶體100彼此間相對間距係核心部107和側間隔部109之尺寸和間距的函數。1D shows a simplified vertical cross-sectional view of a substrate 105 having a plurality of fin field effect transistors 100 formed thereon in accordance with several embodiments of the present invention. During fabrication of the fin field effect transistor 100, a series of core portions 107 are formed to facilitate the formation of the side spacers 109 of each of the core portions 107. The side spacers 109 serve as mask features to facilitate the formation of the lower fin field effect transistor 100. It should be understood that the core portion 107, the side spacer portion 109, and the fin field effect transistor 100 extend longitudinally in a parallel manner, i.e., extend into the page direction as shown in FIG. 1D. It should be understood that core portion 107 and side spacers 109 are ultimately removed and are not present in the as-fabricated semiconductor wafer/device. The relative spacing of the fin field effect transistors 100 from one another is a function of the size and spacing of the core portion 107 and the side spacers 109.
圖1D將核心部107顯示為具有寬度Wb和節距Pb。此外,圖1D將側間隔部109顯示為具有寬度Ws。如此鰭式場效電晶體100可被特徵化為具有一對交替的鰭部節距Ps1、Ps2,其中Ps1係一給定核心部107的側間隔部109之間的平均中心線至中心線節距(Ps1被稱作內鰭部節距),且其中Ps2係相鄰配置的核心部107的相鄰側間隔部109之間的平均中心線至中心線節距(Ps2被稱作外鰭部節距)。假設各個核心部107的寬度Wb、核心部107節距Pb、及側間隔部109寬度Ws係一致的,內鰭部節距Ps1係等於核心部107寬度Wb和側間隔部109寬度Ws的和。並且,外鰭部節距Ps2係等於核心部107節距Pb減去核心部107寬度Wb及側間隔部109寬度Ws的和。因此,內鰭部節距Ps1和外鰭部節距Ps2二者將隨核心部107節距Pb、核心部107寬度Wb、及/或側間隔部109寬度Ws每一者改變而變化。因此,應理解的是,提及一特定的「鰭部節距」,係指一特定鰭部節距的平均,亦即是鰭部節距Ps_ave係等於內鰭部節距Ps1和外鰭部節距Ps2的平均,其中內鰭部節距Ps1和外鰭部節距Ps2每一者本身亦為平均值。圖1D中寬度和節距關係如下: Ps1 = Wb + Ws Ps2 = Pb – Wb – Ws Pb = Ps1 + Ps2 若Ps1 = Ps2 (即一相等鰭部節距),則: Wb + Ws = Pb – Wb – Ws → Pb = 2 (Wb+Ws) Ps1和Ps2可隨Pb、Wb、及/或Ws變化而改變。 因此提及一特定的「鰭部節距」,係指一特定鰭部節距的平均,亦即是Ps_ave係等於平均Ps1、和平均Ps2。FIG. 1D shows the core portion 107 as having a width Wb and a pitch Pb. Further, FIG. 1D shows the side spacer 109 as having a width Ws. Such a FinFET 100 can be characterized as having a pair of alternating fin pitches Ps1, Ps2, where Ps1 is the average centerline to centerline pitch between the side spacers 109 of a given core 107 (Ps1 is referred to as inner fin pitch), and wherein Ps2 is an average center line to centerline pitch between adjacent side spacers 109 of the core portion 107 disposed adjacent to each other (Ps2 is referred to as an outer fin section) distance). Assuming that the width Wb of each core portion 107, the pitch Pb of the core portion 107, and the width Ws of the side spacer portion 109 coincide, the inner fin pitch Ps1 is equal to the sum of the width Wb of the core portion 107 and the width Ws of the side spacer portion 109. Further, the outer fin pitch Ps2 is equal to the sum of the core portion 107 pitch Pb minus the core portion 107 width Wb and the side spacer portion 109 width Ws. Therefore, both the inner fin pitch Ps1 and the outer fin pitch Ps2 will vary with each of the core portion 107 pitch Pb, the core portion 107 width Wb, and/or the side spacer portion width Ws. Therefore, it should be understood that reference to a particular "fin pitch" refers to the average of a particular fin pitch, that is, the fin pitch Ps_ave is equal to the inner fin pitch Ps1 and the outer fin. The average of the pitches Ps2, in which the inner fin pitch Ps1 and the outer fin pitch Ps2 themselves are also average values. The width and pitch relationship in Figure 1D is as follows: Ps1 = Wb + Ws Ps2 = Pb – Wb – Ws Pb = Ps1 + Ps2 If Ps1 = Ps2 (ie an equal fin pitch): Wb + Ws = Pb – Wb – Ws → Pb = 2 (Wb+Ws) Ps1 and Ps2 may change with changes in Pb, Wb, and/or Ws. Therefore, a specific "fin pitch" refers to the average of a particular fin pitch, that is, the Ps_ave is equal to the average Ps1 and the average Ps2.
圖1E顯示根據本發明若干實施例的鰭部節距關係的示圖,其中內鰭部節距Ps1係實質上等於外鰭部節距Ps2。元件高度Hc係等於平均鰭部節距乘上一有理數,即乘以整數x和y的比例,其中x係有理數的分子而y係有理數的分母。在圖1E的實例中,其中內鰭部節距Ps1和外鰭部節距Ps2係相等,平均鰭部節距係等於Ps1和Ps2每一者。因此,元件高度Hc係等於內鰭部節距Ps1或外鰭部節距Ps2任一者乘以該有理數。應理解的是,有理數的分母(y)表示一元件的數量,當該數量的元件以鄰接方式配置於元件高度Hc的方向(即垂直於鰭部縱向方向之方向)時需要該數量元件取得鰭部至元件邊界間距的重複。此外,當有理數的分子(x)可被有理數分母(y)整除時,頂部和底部元件邊界在內鰭部節距Ps1和/或外鰭部節距Ps2係對齊(指向至(indexed to))於元件邊界時可具有相同的鰭部至元件邊界間距。圖1E中高度和節距關係如下: Hc = (x/y)(Ps1) 或 Hc = (x/y)(Ps2),其中x和y係整數 在圖1E的範例中, Ps1 = Ps2 → Pb = 2(Wb+Ws) x=9, y=1 → Hc = (9/1)(Ps1) 或 Hc = (9/1)(Ps2) 因為y=1,鰭部至元件邊界間距係每一元件高度重複一次,並且由於x被y整除,當至少一個鰭部節距(Ps1或Ps2)係與一元件邊界對齊時,頂部和底部元件邊界可具有相同的鰭部至元件邊界間距。1E shows a diagram of a fin pitch relationship in which the inner fin pitch Ps1 is substantially equal to the outer fin pitch Ps2, in accordance with several embodiments of the present invention. The component height Hc is equal to the average fin pitch multiplied by a rational number, ie multiplied by the ratio of the integers x and y, where x is the numerator of the rational number and the y is the denominator of the rational number. In the example of FIG. 1E, where the inner fin pitch Ps1 and the outer fin pitch Ps2 are equal, the average fin pitch is equal to each of Ps1 and Ps2. Therefore, the element height Hc is equal to either the inner fin pitch Ps1 or the outer fin pitch Ps2 multiplied by the rational number. It should be understood that the denominator (y) of the rational number represents the number of elements that are required to be taken when the number of elements are disposed in an abutting manner in the direction of the element height Hc (ie, perpendicular to the longitudinal direction of the fin). Repeat to the component boundary spacing. Furthermore, when the rational number of molecules (x) can be divisible by the rational number denominator (y), the top and bottom element boundaries are aligned at the inner fin pitch Ps1 and/or the outer fin pitch Ps2 (indexed to) The same fin-to-element boundary spacing can be achieved at the element boundaries. The height and pitch relationship in Figure 1E is as follows: Hc = (x/y)(Ps1) or Hc = (x/y)(Ps2), where x and y are integers in the example of Figure 1E, Ps1 = Ps2 → Pb = 2(Wb+Ws) x=9, y=1 → Hc = (9/1)(Ps1) or Hc = (9/1)(Ps2) Since y=1, the fin-to-element boundary is each The element height is repeated once, and since x is divisible by y, the top and bottom element boundaries may have the same fin-to-element boundary spacing when at least one fin pitch (Ps1 or Ps2) is aligned with an element boundary.
圖1F顯示根據本發明若干實施例之圖1E的鰭部節距關係示圖的變化,其中有理數的分母(y)係二。因此,在圖1F中,鰭部至元件邊界間距每二個元件高度Hc會重複。此外,在圖1F的範例中,有理數分子(x)不被有理數分母(y)所整除。因此,當內鰭部節距Ps1和/或外鰭部節距Ps2係對齊(指向(indexed to))於元件邊界時,頂部和底部鰭部至元件邊界間距將會不同。圖1F中高度和節距關係如下: Hc = (x/y)(Ps1) 或 Hc = (x/y)(Ps2),其中x和y係整數 在圖1F的範例中, Ps1 = Ps2 → Pb = 2(Wb+Ws) x=17, y=2 → Hc = (17/2)(Ps1) 或 Hc = (17/2)(Ps2) 因為y=2,鰭部至元件邊界間距係每二元件高度重複一次,並且由於x無法被y整除,當至少一個鰭部節距(Ps1或Ps2)係與一元件邊界對齊時,頂部和底部元件邊界將具有不同的鰭部至元件邊界間距。1F shows a variation of the fin pitch relationship diagram of FIG. 1E in accordance with several embodiments of the present invention, wherein the denominator (y) of the rational number is two. Therefore, in FIG. 1F, the fin-to-element boundary pitch is repeated every two element heights Hc. Furthermore, in the example of Fig. 1F, the rational number molecule (x) is not divisible by the rational number denominator (y). Therefore, when the inner fin pitch Ps1 and/or the outer fin pitch Ps2 are aligned (indexed to) to the element boundary, the top and bottom fin-to-element boundary spacing will be different. The height and pitch relationship in Figure 1F is as follows: Hc = (x/y)(Ps1) or Hc = (x/y)(Ps2), where x and y are integers in the example of Figure 1F, Ps1 = Ps2 → Pb = 2(Wb+Ws) x=17, y=2 → Hc = (17/2)(Ps1) or Hc = (17/2)(Ps2) Since y=2, the fin-to-element boundary is every two The element height is repeated once, and since x cannot be divisible by y, the top and bottom element boundaries will have different fin-to-element boundary spacing when at least one fin pitch (Ps1 or Ps2) is aligned with an element boundary.
圖1G顯示根據本發明若干實施例之圖1E的鰭部節距關係示圖的變化,其中有理數的分母(y)係三。因此,在圖1G中,鰭部至元件邊界間距每三個元件高度Hc會重複。此外,在圖1G的範例中,有理數分子(x)不被有理數分母(y)所整除。因此,當內鰭部節距Ps1和/或外鰭部節距Ps2係對齊(指向(indexed to))於元件邊界時,頂部和底部鰭部至元件邊界間距將會不同。應理解的是,有理數可由用以取得在元件高度Hc方向任何所欲鰭部至元件邊界間距重複頻率及/或任何所欲鰭部至元件邊界間距規格所需的任何方式加以定義。1G shows a variation of the fin pitch relationship diagram of FIG. 1E in accordance with several embodiments of the present invention, wherein the denominator (y) of the rational number is three. Therefore, in FIG. 1G, the fin-to-element boundary pitch is repeated every three element heights Hc. Furthermore, in the example of Figure 1G, the rational number molecule (x) is not divisible by the rational number denominator (y). Therefore, when the inner fin pitch Ps1 and/or the outer fin pitch Ps2 are aligned (indexed to) to the element boundary, the top and bottom fin-to-element boundary spacing will be different. It should be understood that the rational number may be defined by any means needed to achieve any desired fin-to-element boundary spacing repetition frequency and/or any desired fin-to-element boundary spacing specification in the component height Hc direction.
圖1H顯示根據本發明若干實施例之圖1E的鰭部節距關係示圖的更廣義版本,其中內鰭部節距Ps1和外鰭部節距Ps2係不同。在這個範例中,外鰭部節距Ps2係大於內鰭部節距Ps1。應理解的是,元件高度Hc係等於平均鰭部節距Ps_ave 乘以有理數(x/y),其中x和y係整數。此外,應理解的是,整數y表示在元件高度Hc方向上鰭部至元件邊界間距的重複頻率。此外,應理解的是,當有理數(x/y)化簡為一整數值(即當x被y整除)時,頂部和底部鰭部至元件邊界間距可彼此相等。如果有理數(x/y)不能化簡為一整數值,一特定元件的不同鰭部相位變化可定義於元件庫,其中各個鰭部相位變化對應該特定元件的不同可能的鰭部至元件邊界間距關係。此外,一特定元件的可能鰭部相位變化數量將等於在數學上最簡型式之有理數(x/y)的分母(y)。圖1G中高度和節距關係如下: Hc = (x/y)(Ps1) 或 Hc = (x/y)(Ps2),其中x和y係整數 在圖1G的範例中, Ps1 = Ps2 → Pb = 2(Wb+Ws) x=25, y=3 → Hc = (25/3)(Ps1) 或 Hc = (25/3)(Ps2) 因為y=3,鰭部至元件邊界間距係每三元件高度重複一次,並且由於x無法被y整除,當至少一個鰭部節距(Ps1或Ps2)係與一元件邊界對齊時,頂部和底部元件邊界將具有不同的鰭部至元件邊界間距。1H shows a broader version of the fin pitch relationship diagram of FIG. 1E in which the inner fin pitch Ps1 and the outer fin pitch Ps2 are different, in accordance with several embodiments of the present invention. In this example, the outer fin pitch Ps2 is greater than the inner fin pitch Ps1. It should be understood that the component height Hc is equal to the average fin pitch Ps_ave multiplied by the rational number (x/y), where x and y are integers. Further, it should be understood that the integer y represents the repetition frequency of the fin-to-element boundary pitch in the element height Hc direction. Furthermore, it should be understood that when the rational number (x/y) is reduced to an integer value (ie, when x is divisible by y), the top and bottom fin-to-element boundary spacings may be equal to each other. If the rational number (x/y) cannot be reduced to an integer value, the different fin phase changes of a particular component can be defined in the component library, where each fin phase change corresponds to a different possible fin-to-element spacing of the particular component. relationship. Furthermore, the number of possible fin phase changes for a particular component will be equal to the denominator (y) of the mathematically simplest rational number (x/y). The height and pitch relationship in Figure 1G is as follows: Hc = (x/y)(Ps1) or Hc = (x/y)(Ps2), where x and y are integers in the example of Figure 1G, Ps1 = Ps2 → Pb = 2(Wb+Ws) x=25, y=3 → Hc = (25/3)(Ps1) or Hc = (25/3)(Ps2) Since y=3, the fin-to-element boundary is every three The element height is repeated once, and since x cannot be divisible by y, the top and bottom element boundaries will have different fin-to-element boundary spacing when at least one fin pitch (Ps1 or Ps2) is aligned with an element boundary.
如以上所探討的,圖1H顯示根據本發明若干實施例使用二個不同的擴散鰭部節距Ps1和Ps2。更具體而言,在圖1H中每隔一對相鄰配置的擴散鰭部結構依據較小的節距Ps1加以配置。在若干實施例中,較大的擴散鰭部節距Ps2係約80奈米(nm)且較小的擴散鰭部節距Ps1係約60 nm。然而,應理解的是,在其他實施例中,較小的擴散鰭部節距Ps1可為任何尺寸,且較大的擴散鰭部Ps2可為任何尺寸。應理解的是,若干實施例在一特定元件或區塊之內可利用超過二個擴散鰭部節距。並且,若干實施例在一特定元件或區塊之內可利用單一擴散鰭部節距。此外,應理解的是,半導體裝置的任何層或其部分,可以類似於此處所述關於擴散鰭部節距的方式加以形成。舉例來說,半導體裝置的一局部內連線層或一高階層內連線層或其部分,可包含以類似於此處所述關於擴散鰭部節距之方式依一個以上對應節距所形成的內連線傳導結構。圖1H中高度和節距關係如下: Hc = (x/y)(Ps_ave),其中x和y係整數,且 Ps_ave係平均鰭部節距,例如[(Ps1+Ps2)/2] 在圖1H的範例中, Ps2 > Ps1 x=10, y=1 → Hc = (10/1)(Ps_ave) 因為y=1,鰭部至元件邊界間距係每一元件高度重複一次,並且由於x被y整除,當至少一個鰭部節距(Ps1或Ps2)係與一元件邊界對齊時,頂部和底部元件邊界可具有相同的鰭部至元件邊界間距。As discussed above, Figure 1H shows the use of two different diffuser fin pitches Ps1 and Ps2 in accordance with several embodiments of the present invention. More specifically, every other pair of adjacently disposed diffusing fin structures in FIG. 1H is configured in accordance with a smaller pitch Ps1. In several embodiments, the larger diffusing fin pitch Ps2 is about 80 nanometers (nm) and the smaller diffusing fin pitch Ps1 is about 60 nm. However, it should be understood that in other embodiments, the smaller diffusion fin pitch Ps1 can be any size, and the larger diffusion fin Ps2 can be any size. It should be understood that several embodiments may utilize more than two diffuser fin pitches within a particular component or block. Also, several embodiments may utilize a single diffusing fin pitch within a particular component or block. Moreover, it should be understood that any layer or portion of the semiconductor device can be formed in a manner similar to that described herein with respect to the pitch of the diffusion fins. For example, a portion of the interconnect layer or a high level interconnect layer or portion thereof of the semiconductor device can comprise a plurality of corresponding pitches formed in a manner similar to the diffusion fin pitch described herein. The interconnect structure of the interconnect. The height and pitch relationship in Figure 1H is as follows: Hc = (x/y)(Ps_ave), where x and y are integers, and Ps_ave is the average fin pitch, for example [(Ps1+Ps2)/2] in Figure 1H In the example, Ps2 > Ps1 x=10, y=1 → Hc = (10/1)(Ps_ave) Since y=1, the fin-to-element boundary spacing is repeated once for each component height, and since x is divisible by y When at least one fin pitch (Ps1 or Ps2) is aligned with an element boundary, the top and bottom element boundaries may have the same fin-to-element boundary spacing.
由於閘極氧化物限制及/或源極/汲極漏流定比問題,電晶體縮放在45奈米(nm)關鍵尺寸以下已減緩。鰭式場效電晶體藉由從三側控制鰭式場效電晶體的通道減緩這些問題。在鰭式場效電晶體的通道中增加的電場增進I-on(開啟驅動電流)及I-off(次臨界漏電流)之間的關係。鰭式場效電晶體可應用於22 nm及以下之關鍵尺寸。然而,由於其垂直的突出,鰭式場效電晶體在各種電路佈局中可能有受限制的配置。舉例來說,可能有必要的鰭式場效電晶體之間最小間距、和/或必要的鰭式場效電晶體之間的最小節距等等。此處揭露的元件佈局的實施例,其以改進佈局縮放的方式運用鰭式場效電晶體。Due to gate oxide limitations and/or source/drain leakage ratio problems, transistor scaling has slowed below the 45 nanometer (nm) critical dimension. Fin field effect transistors alleviate these problems by controlling the channels of the fin field effect transistors from three sides. The increased electric field in the channel of the fin field effect transistor enhances the relationship between I-on (on drive current) and I-off (sub-critical leakage current). Fin field effect transistors are available for critical dimensions up to 22 nm. However, due to its vertical protrusion, fin field effect transistors may have a limited configuration in various circuit layouts. For example, it may be necessary to have a minimum spacing between fin field effect transistors, and/or a minimum pitch between the necessary fin field effect transistors, and the like. Embodiments of the component layout disclosed herein utilize a fin field effect transistor in a manner that improves layout scaling.

In several embodiments, the diffusion fins of a plurality of adjacent elements will be configured according to a common global diffusion fin pitch, thereby facilitating wafer level fabrication of the diffusion fins in the plurality of elements.
應理解的是,其他實施例可能在一特定元件之內或一群元件之間使用多個擴散鰭部節距。舉例來說,圖2H顯示根據本發明若干實施例之圖2A的元件的變化,其中使用二個不同的擴散鰭部節距203和205。應理解的是,在若干實施例中,擴散鰭部201A/201B可根據一個以上縱向中心線至縱向中心線節距而配置,或者可以相對於縱向中心線至縱向中心線間距無限制的方式加以配置。此外,在若干實施例中,擴散鰭部201A/201B可根據一特定的節距加以配置,且若干節距位置可能關於擴散鰭部配置係未使用的。此外,在若干實施例中,可將擴散鰭部以分隔開、端到端的方式配置於一元件之內的特定擴散鰭部節距位置。It should be understood that other embodiments may use multiple diffusing fin pitches within a particular component or between a group of components. For example, Figure 2H shows a variation of the elements of Figure 2A in accordance with several embodiments of the present invention in which two different diffusion fin pitches 203 and 205 are used. It should be understood that in several embodiments, the diffusion fins 201A/201B may be configured according to more than one longitudinal centerline to longitudinal centerline pitch, or may be provided in an unrestricted manner relative to the longitudinal centerline to longitudinal centerline spacing.

Moreover, in several embodiments, the diffusing fins can be disposed in a spaced apart, end-to-end configuration at a particular diffusing fin pitch location within an element.
在此處所示各圖形中,各擴散鰭部(例如圖2A中的擴散鰭部201A/201B)係為n型擴散材料或p型擴散材料。此外,取決於特定的元件實現方式,擴散鰭部的材料類型可加以交換,以取得不同的元件邏輯功能。因此,在圖示中使用類型1擴散鰭部和類型2擴散鰭部標示,以表示擴散鰭部的不同材料類型。舉例來說,若類型1擴散鰭部材料係n型材料,則類型2擴散鰭部材料係p型材料,反之亦然。In each of the figures shown here, each of the diffusion fins (for example, the diffusion fins 201A/201B in FIG. 2A) is an n-type diffusion material or a p-type diffusion material. Furthermore, depending on the particular component implementation, the material types of the diffusion fins can be exchanged to achieve different component logic functions. Thus, Type 1 diffuser fins and Type 2 diffuser fins are used in the illustration to indicate different material types of the diffusing fins. For example, if the Type 1 diffused fin material is an n-type material, then the Type 2 diffused fin material is a p-type material and vice versa.
元件佈局亦包含數個線形閘極電極結構207。線形閘極電極結構207在實質上垂直於擴散鰭部201A/201B的方向延伸,即在第二方向(y)延伸。當製造時,線形閘極電極結構207覆蓋於擴散鰭部201A/201B的上方,以形成鰭式場效電晶體的閘極電極。應理解的是,適當的閘極氧化物材料係佈置(即配置/沉積)於擴散鰭部201A/201B和形成於其上的閘極電極結構207之間。The component layout also includes a plurality of linear gate electrode structures 207. The linear gate electrode structure 207 extends in a direction substantially perpendicular to the diffusion fins 201A/201B, that is, in a second direction (y). When fabricated, a linear gate electrode structure 207 overlies the diffusion fins 201A/201B to form a gate electrode of the fin field effect transistor. It should be understood that a suitable gate oxide material is disposed (ie, configured/deposited) between the diffusion fins 201A/201B and the gate electrode structure 207 formed thereon.

應理解的是,在一特定元件中若干閘極節距位置可由閘極電極結構207所佔用,而在該特定元件中的其他閘極節距位置則維持未占用。因此,應理解的是,多個閘極電極結構207可以分隔開、端到端的方式在一特定元件之內沿著任何閘極電極節距位置加以配置。更應理解的是,在若干實施例中,可將閘極電極結構207根據一個以上閘極節距加以配置,或者可以相對於閘極節距無限制的方式加以配置。It should be understood that a number of gate pitch locations in a particular component may be occupied by the gate electrode structure 207 while other gate pitch locations in that particular component remain unoccupied. Thus, it should be understood that the plurality of gate electrode structures 207 can be disposed in a spaced apart, end-to-end manner along any gate electrode pitch location within a particular component. It will be further appreciated that in several embodiments, the gate electrode structure 207 can be configured in accordance with more than one gate pitch, or can be configured in an unrestricted manner relative to the gate pitch.
元件佈局亦可包含數個線形水平局部內連線結構(lih)211、及/或數個線形垂直局部內連線結構(liv)213。垂直局部內連線結構213係定向成平行於閘極電極結構207。水平局部內連線結構211係定向成平行於擴散鰭部201A/201B。在若干實施例中,垂直局部內連線結構213的配置,係定義成以半個閘極節距而與閘極電極結構207的配置異相。因此,在這個實施例中,當各垂直局部內連線結構213的相鄰閘極電極結構207係配置於閘極節距上,該垂直局部內連線結構213係位於其相鄰閘極結構207之間的中心。因此,在這個實施例中,相鄰配置的垂直局部內連線結構213將具有與一局部閘極節距或一全域閘極節距相等的中心到中心間距,其中局部閘極節距係適用於一特定元件之內,而全域閘極節距係適用在遍及多個元件的範圍內。The component layout may also include a plurality of linear horizontal local interconnect structures (lih) 211, and/or a plurality of linear vertical local interconnect structures (liv) 213. The vertical partial interconnect structure 213 is oriented parallel to the gate electrode structure 207. The horizontal partial interconnect structure 211 is oriented parallel to the diffusion fins 201A/201B. In some embodiments, the configuration of the vertical local interconnect structure 213 is defined to be out of phase with the configuration of the gate electrode structure 207 at a half gate pitch. Therefore, in this embodiment, when the adjacent gate electrode structures 207 of the respective vertical partial interconnect structures 213 are disposed on the gate pitch, the vertical partial interconnect structures 213 are located in their adjacent gate structures. Center between 207. Thus, in this embodiment, adjacently disposed vertical partial interconnect structures 213 will have a center-to-center spacing equal to a local gate pitch or a global gate pitch, where local gate pitch is applicable. Within a particular component, the global gate pitch is applicable over a range of components.
在若干實施例中,水平局部內連線結構211的配置,係定義成以半個擴散鰭部節距而與擴散鰭部201A/201B的配置異相。因此,在這個實施例中,當水平局部內連線結構211的相鄰擴散鰭部201A/201B係配置於擴散鰭部節距上,該水平局部內連線結構211可位於其相鄰擴散鰭部201A/201B之間的中心。因此,在這個實施例中,相鄰配置的水平局部內連線結構211將具有與一局部擴散鰭部節距或一全域擴散鰭部節距相等的中心到中心間距,其中局部擴散鰭部節距係適用於一特定元件之內,而全域擴散鰭部節距係適用在遍及多個元件的範圍內。In several embodiments, the configuration of the horizontal partial interconnect structure 211 is defined to be out of phase with the configuration of the diffuser fins 201A/201B at a half diffuse fin pitch. Therefore, in this embodiment, when the adjacent diffusion fins 201A/201B of the horizontal partial interconnect structure 211 are disposed on the diffusion fin pitch, the horizontal partial interconnect structure 211 may be located adjacent to the diffusion fins thereof. The center between the parts 201A/201B. Thus, in this embodiment, the adjacently disposed horizontal partial interconnect structures 211 will have a center-to-center spacing equal to a local diffused fin pitch or a global diffused fin pitch, wherein the locally diffused fin sections The distance system is suitable for use within a particular component, and the global diffusion fin pitch is suitable for use over a range of components.
在若干實施例中,元件佈局亦包含數個線形金屬層1(met1)內連線結構215。此met1內連線結構215係定向成平行於擴散鰭部201A/201B且垂直於閘極電極結構207。在若干實施例中,met1內連線結構215的配置,係定義成以半個擴散鰭部節距而與擴散鰭部201A/201B的配置異相。因此,在這個實施例中,雖然在較高的晶片階層內,當各met1內連線結構215的相鄰擴散鰭部係配置於擴散鰭部節距上,該met1內連線結構215係位於其相鄰擴散鰭部之間的中心。因此,在這個實施例中,相鄰配置的met1內連線結構215將具有與一局部擴散鰭部節距或一全域擴散鰭部節距相等的中心到中心間距,其中局部擴散鰭部節距係適用於一特定元件之內,而全域擴散鰭部節距係適用在遍及多個元件的範圍內。在若干實施例中,met1內連線結構215節距,以及由此之擴散軌道節距,係設定於單一曝光微影限制,例如1.35 NA及193 nm波長光用之80 nm。在這個實施例中,不需要雙重曝光微影,即多重圖案化,來製造met1內連線結構215。應理解的是,其他實施例可使用定向成垂直於擴散鰭部201A/201B且平行於閘極電極結構207的met1內連線結構215。In some embodiments, the component layout also includes a plurality of linear metal layer 1 (met1) interconnect structures 215. This met1 interconnect structure 215 is oriented parallel to the diffusion fins 201A/201B and perpendicular to the gate electrode structure 207. In several embodiments, the configuration of the met1 interconnect structure 215 is defined to be out of phase with the configuration of the diffuser fins 201A/201B at a half diffusion fin pitch. Therefore, in this embodiment, although in the higher wafer level, when the adjacent diffusion fins of each of the met1 interconnect structures 215 are disposed on the diffusion fin pitch, the met1 interconnect structure 215 is located. The center between its adjacent diffusing fins. Thus, in this embodiment, the adjacently configured met1 interconnect structures 215 will have a center-to-center spacing equal to a local diffused fin pitch or a global diffused fin pitch, wherein the local diffused fin pitch The system is suitable for use within a particular component, and the global diffusion fin pitch is applicable over a range of components. In several embodiments, the pitch of the me1 interconnect structure 215, and thus the spread track pitch, is set at a single exposure lithography limit, such as 1.3 nm for 1.35 NA and 193 nm wavelength light. In this embodiment, dual exposure lithography, i.e., multiple patterning, is not required to fabricate the me1 interconnect structure 215. It should be understood that other embodiments may use a metl interconnect structure 215 that is oriented perpendicular to the diffusion fins 201A/201B and parallel to the gate electrode structure 207.
元件佈局亦包含數個接觸窗217,其用以將各種met1內連線結構215連接至各種局部內連線結構211/213及閘極電極結構207,藉此提供實行元件邏輯功能所需的各種鰭式場效電晶體之間的電連接。在若干實施例中,接觸窗217係定義成滿足單一曝光微影限制。舉例來說,在若干實施例中,接觸窗217所需連接的佈局特徵部係分隔開到足以進行接觸窗217的單一曝光製造。舉例來說,met1內連線結構215係定義成其用以接受接觸窗217的線端,係與亦接受接觸窗217之相鄰met1內連線結構215的線端足夠分隔開,俾使接觸窗217之間的空間距離大到足以進行接觸窗217的單一曝光微影製程。在若干實施例中,相鄰接觸窗217係以至少1.5倍閘極節距彼此分隔。應理解的是,藉由將met1內連線結構215的對向的線端足夠地分離,可消除雙重曝光微影製程之線端切割(line end cutting)及相關聯的增加費用。應理解的是,取決於在製造過程中的選擇,金屬層上的接觸窗間隔和線端間隔在若干實施例中可相互獨立。The component layout also includes a plurality of contact windows 217 for connecting various met1 interconnect structures 215 to various local interconnect structures 211/213 and gate electrode structures 207, thereby providing the various functions required to perform component logic functions. Electrical connection between fin field effect transistors. In several embodiments, the contact window 217 is defined to satisfy a single exposure lithography limit. For example, in several embodiments, the layout features that the contact window 217 is required to connect are separated into a single exposure fabrication sufficient to make the contact window 217. For example, the met1 interconnect structure 215 is defined as the line end for receiving the contact window 217, which is sufficiently separated from the line end of the adjacent met1 interconnect structure 215 that also receives the contact window 217. The spatial distance between the contact windows 217 is large enough to perform a single exposure lithography process of the contact window 217. In several embodiments, adjacent contact windows 217 are separated from each other by at least 1.5 times the gate pitch. It will be appreciated that by sufficiently separating the opposing line ends of the met1 interconnect structure 215, line end cutting of the double exposure lithography process and associated increased cost can be eliminated. It will be appreciated that the contact window spacing and line end spacing on the metal layer may be independent of each other in several embodiments, depending on the choices made during the manufacturing process.
在若干實施例中,元件佈局也包含數個線形金屬層2(met2)內連線結構219。該met2內連線結構219係定向成平行於閘極電極207且垂直於擴散鰭部201A/201B。met2內連線結構219依實行元件邏輯功能的需要可透過介層窗結構(v1)221與met1內連線結構215物理性連接。雖然圖2A的例示元件顯示以縱向方式延伸垂直於閘極電極結構207的met1內連線結構215以及以縱向方式延伸平行於閘極電極結構207的met2內連線結構219,應理解的是在其他實施例中met1內連線結構215和met2內連線結構219可定義成以任何相對於閘極電極結構207的方向延伸。應理解的是,其他實施例可使用定向成垂直於閘極電極207且平行於擴散鰭部201A/201B的met2內連線結構219。In several embodiments, the component layout also includes a plurality of linear metal layer 2 (met2) interconnect structures 219.

The met2 interconnect structure 219 is physically coupled to the met1 interconnect structure 215 via a via structure (v1) 221 as required to perform the logic function of the component. Although the exemplary component of FIG. 2A shows a met1 interconnect structure 215 that extends perpendicular to the gate electrode structure 207 in a longitudinal direction and a met2 interconnect structure 219 that extends parallel to the gate electrode structure 207 in a longitudinal direction, it should be understood that In other embodiments, the met1 interconnect structure 215 and the met2 interconnect structure 219 may be defined to extend in any direction relative to the gate electrode structure 207. It should be understood that other embodiments may use a met2 interconnect structure 219 oriented perpendicular to the gate electrode 207 and parallel to the diffusion fins 201A/201B.

Figure 31B shows the illustrated sdff element layout of Figure 31A in which a substantially central partial interconnect line end gap between the diffuser fins is circled. Based on Figures 31A through 31B, it will be appreciated that a component library structure can be created in which all gate electrodes and vertical interconnect line end gaps are substantially centered between the diffuser fins. 31C shows an exemplary sdff element layout of FIGS. 31A and 31B with an annotation of a region 3105 between two adjacent gate electrode structures, wherein the diffusion fin ends overlap each other in the x direction, in accordance with several embodiments of the present invention.
根據本發明若干實施例,圖32-34顯示標準元件電路佈局的一部分之三個範例。圖32顯示一例示佈局,其中所有將所有接觸層結構配置於擴散鰭部之間。圖33和34顯示例示佈局,其中將所有接觸層結構配置於擴散鰭部之上。在圖32的例子中,閘極電極線端間隙在若干實例中係實質上位於擴散鰭部上方的中心,如圓3201所標示,且在若干實例中,閘極電極線端間隙係實質上位於擴散鰭部之間的中心,如圓3203所標示。藉由利用將所有接觸層結構配置於擴散鰭部上方的一元件結構,所有閘極電極線端間隙可實質上位於擴散鰭部之間的中心,如在圖33和34之中的圓3301所標示。此處的一個優點係閘極電極線端間隙係皆具一固定的節距。從製造的觀點,閘極電極線端間隙是否在擴散鰭部上或擴散鰭部之間的中心處是不要緊的。然而,閘極電極線端間隙沒有混雜則是要緊的,如圖32的範例所示。使閘極電極線端間隙皆具相同節距會導致閘極電極製造過程較不昂貴、或更可靠、或滿足以上二者。Figures 32-34 show three examples of a portion of a standard component circuit layout, in accordance with several embodiments of the present invention. Figure 32 shows an exemplary layout in which all of the contact layer structures are disposed between the diffusion fins. Figures 33 and 34 show an exemplary layout in which all of the contact layer structures are disposed over the diffuser fins. In the example of FIG. 32, the gate electrode line end gap is substantially centered over the diffuser fin in several instances, as indicated by circle 3201, and in some examples, the gate electrode line end gap is substantially located The center between the diffusing fins is indicated by circle 3203. By utilizing an element structure in which all contact layer structures are disposed over the diffusion fins, all gate electrode line end gaps can be substantially centered between the diffusion fins, as in circle 3301 in Figures 33 and 34. Marked. One advantage here is that the gate electrode line gaps have a fixed pitch. From a manufacturing point of view, it does not matter whether the gate electrode line end gap is at the center of the diffusion fin or between the diffusion fins. However, it is important that the gate electrode end gaps are not mixed, as shown in the example of FIG. Having the same pitch at the gate end of the gate electrode results in a gate electrode fabrication process that is less expensive, more reliable, or both.

It should be understood that the component layouts of Figures 35A/B through 69A/B show examples that may be implemented using a fin field effect transistor cross-connect transistor configuration and do not represent all of the included sets of possible component layout configurations. Any of the features shown in the various component layout examples of Figures 35A/B through 69A/B can be combined to create additional component layouts.
光學解析度不足以直接解析線圖案的技術,將會使用若干型式的節距分割(pitch division)。節距分割可在可達成的解析度上經由多個曝光步驟或利用間格部加以自對準。舉例來說,對於使用水浸最末透鏡的ArF準分子雷射掃描器及曝光之晶圓的一部分,光學解析度係限制至~40 nm。這相當於1.35有效數值孔徑與波長193 nm的k1值0.28。對於擴散鰭部層和閘極電極層和利用節距分割所形成的其他層(例如間隔物雙重圖案化、間隔物四重圖案化、多重曝光微影-蝕刻-微影-蝕刻等等),縱使佈局係以傳導結構用(即用於該等線)的均勻節距(縱向中心線至縱向中心線節距)加以進行,製造後傳導結構可能由於處理變異而輕微地偏離目標,使得最終晶圓上有多個(例如:二、四等等)節距。A technique in which the optical resolution is insufficient to directly resolve the line pattern will use several types of pitch division. The pitch segmentation can be self-aligned over a plurality of exposure steps or using a bay portion at an achievable resolution. For example, for an ArF excimer laser scanner using a water immersed lens and a portion of the exposed wafer, the optical resolution is limited to ~40 nm. This is equivalent to a 1.35 effective numerical aperture and a k1 value of 0.28 at a wavelength of 193 nm. For the diffusion fin layer and the gate electrode layer and other layers formed by the pitch division (for example, spacer double patterning, spacer quadruple patterning, multiple exposure lithography-etching-lithography-etching, etc.), Even though the layout is performed with a uniform pitch (longitudinal centerline to longitudinal centerline pitch) for the conductive structure (ie for the lines), the post-production conductive structure may slightly deviate from the target due to processing variations, resulting in a final crystal There are multiple (for example: two, four, etc.) pitches on the circle.
可與自對準間隔物方式或多重微影曝光法一起,應用節距分割多次,例如以二節距分割(pitch-division-by-2)、以四節距分割(pitch-division-by-4)。以四節距分割已被記載達成約11 nm的線/間格。節距分割的一個限制係結果的線圖案可在圖案之內具有些微不同的節距。對於以二節距分割,這意指二條線的群組將具有一個節距,其下一個二條線的群組可能具有些微不同的節距,下一個二線群組將會具有與第一群組相等的節距等等。在所完成晶圓上的結果將會是意欲達到具均勻的、固定的節距的線,但該等最終會具有二或四或其他多種的節距。對於自對準間隔部,將依一固定的、均勻的節距繪製原始核心線圖案。對於多重曝光,曝光每一者將會具有以均勻固定節距所繪製的線。由節距分割過程所引入的非均勻節距可能會在10%或更少最終節距的等級。舉例來說,對於最終目標節距50 nm,二條線群組每一者的節距可能有小於5 nm的差異。受限制的閘極階層佈局結構 The pitch can be divided multiple times together with the self-aligned spacer method or the multiple lithography exposure method, for example, pitch-division-by-2, split-division-by -4). Segmentation at four pitches has been documented to achieve a line/space of approximately 11 nm. One limitation of pitch segmentation is that the resulting line pattern can have slightly different pitches within the pattern. For splitting by two pitches, this means that the group of two lines will have a pitch, the group of the next two lines may have a slightly different pitch, and the next two-line group will have the same group Group equal pitch and so on. The result on the finished wafer will be to achieve a line with a uniform, fixed pitch, but these will eventually have two or four or many other pitches. For self-aligned spacers, the original core line pattern will be drawn at a fixed, uniform pitch. For multiple exposures, each of the exposures will have a line drawn at a uniform fixed pitch. The non-uniform pitch introduced by the pitch segmentation process may be at the level of 10% or less final pitch. For example, for a final target pitch of 50 nm, the pitch of each of the two line groups may have a difference of less than 5 nm. Restricted gate level layout structure
如以上所探討,包含鰭式場效電晶體的各種電路佈局,可在一限制的閘極階層佈局結構之內加以施行。對於閘極階層,數條平行虛擬線定義成延伸通過該佈局。這些平行虛擬線係稱作閘極電極軌道,因為它們係用以指示在佈局之內各種電晶體的閘極電極的配置。在若干實施例中,形成閘極電極軌道的平行虛擬線,係由與指定的閘極電極節距相等的其間垂直間距加以界定。因此,在閘極電極軌道上的閘極電極區段的配置係對應於該指定的閘極電極節距。在另一實施例中,閘極電極軌道可由大於或等於一指定閘極電極節距的可變節距加以分隔開。As discussed above, various circuit layouts including fin field effect transistors can be implemented within a limited gate level layout structure. For the gate level, a number of parallel virtual lines are defined to extend through the layout. These parallel virtual lines are referred to as gate electrode tracks because they are used to indicate the configuration of the gate electrodes of the various transistors within the layout. In several embodiments, the parallel imaginary lines forming the gate electrode tracks are defined by their vertical spacing equal to the specified gate electrode pitch. Thus, the configuration of the gate electrode segments on the gate electrode tracks corresponds to the specified gate electrode pitch. In another embodiment, the gate electrode tracks may be separated by a variable pitch greater than or equal to a specified gate electrode pitch.
根據本發明若干實施例,圖70A顯示在受限制的閘極階層佈局結構之內所定義的閘極電極軌道70-1A至70-1E的範例。閘極電極軌道70-1A至70-1E係由延伸通過晶片的閘極階層佈局的平行虛擬線所形成,其具有等於一指定閘極電極節距70-3的垂直間距於其間。Figure 70A shows an example of gate electrode tracks 70-1A through 70-1E defined within a restricted gate level layout structure, in accordance with several embodiments of the present invention. The gate electrode tracks 70-1A through 70-1E are formed by parallel imaginary lines extending through the gate level layout of the wafer with a vertical pitch equal to a specified gate electrode pitch 70-3 therebetween.
在受限制的閘極階層佈局結構之內,閘極階層特徵佈局通道係關於一特定閘極電極軌道而加以定義,以在與該特定閘極電極軌道相鄰的閘極電極軌道之間延伸。舉例來說,閘極階層特徵佈局通道70-5A至70-5E係分別關於閘極電極軌道70-1A至70-1E而加以定義。應理解的是,各閘極電極軌道具有對應的閘極階層特徵佈局通道。此外,對於配置成與一規定的佈局空間的邊緣相鄰(例如與元件邊界相鄰)之閘極電極軌道,對應的閘極階層特徵佈局通道延伸成就如在該規定佈局空間外側的虛擬閘極電極軌道,如閘極階層特徵佈局通道70-5A及70-5E所描述。更應理解的是,各閘極階層特徵佈局通道係定義成沿著其對應閘極電極軌道的全部長度延伸。因此,各閘極階層特徵佈局通道係定義成延伸通過在該閘極階層佈局所關聯之晶片的一部份之內的該閘極階層佈局。Within the restricted gate level layout structure, the gate level feature layout channel is defined with respect to a particular gate electrode track to extend between the gate electrode tracks adjacent to the particular gate electrode track. For example, the gate level feature layout channels 70-5A through 70-5E are defined with respect to the gate electrode tracks 70-1A through 70-1E, respectively. It should be understood that each gate electrode track has a corresponding gate level feature layout channel. In addition, for a gate electrode track that is disposed adjacent to an edge of a prescribed layout space (eg, adjacent to an element boundary), the corresponding gate level feature layout channel extends as a virtual gate outside the specified layout space Electrode tracks, as described in the gate level feature layout channels 70-5A and 70-5E. It should be further understood that each gate level feature layout channel is defined to extend along the entire length of its corresponding gate electrode track. Thus, each gate level feature layout channel is defined to extend through the gate level layout within a portion of the wafer associated with the gate level layout.
在受限制的閘極階層佈局結構中,與一特定閘極電極軌道相關聯的閘極階層特徵係定義在與該特定閘極電極軌道相關聯的閘極階層特徵佈局通道之內。一連續的閘極階層特徵可包含定義一電晶體的閘極電極的部分(如此處所揭露的鰭式場效電晶體)、及未定義一電晶體的閘極電極的部分二者。因此,一連續閘極階層特徵可延伸於一擴散區域(即擴散鰭部)及一下方晶片階層的介電區域二者上方。In a restricted gate level layout structure, a gate level feature associated with a particular gate electrode track is defined within a gate level feature layout channel associated with the particular gate electrode track. A continuous gate level feature can include both portions defining a gate electrode of a transistor (such as the fin field effect transistor disclosed herein), and portions of a gate electrode not defining a transistor. Thus, a continuous gate level feature can extend over both a diffusion region (ie, a diffusion fin) and a dielectric region of a lower wafer level.
在若干實施例中,將形成一電晶體的閘極電極的閘極階層特徵的各部分,配置成實質上位於一特定閘極電極軌道的中心。此外,在這個實施例中,不形成一電晶體的閘極電極的閘極階層特徵的部分,可配置於與該特定閘極軌道相關聯的閘極階層特徵佈局通道之內。因此,一特定閘極階層特徵可實質上定義在一特定閘極階層特徵佈局通道之內的任何位置,只要該特定閘極階層特徵的閘極電極部分在對應該特定閘極階層佈局特徵的閘極電極軌道的中心,且只要該特定閘極階層特徵相對於在相鄰閘極階層佈局通道中的其他閘極階層特徵符合設計法則間距規定。此外,定義於與相鄰閘極電極軌道相關聯的閘極階層特徵通道中的閘極階層特徵之間的物理性接觸係不允許的。In some embodiments, portions of the gate level features of the gate electrode forming a transistor are configured to be substantially centered on a particular gate electrode track. Moreover, in this embodiment, the portion of the gate level feature of the gate electrode that does not form a transistor can be disposed within the gate level feature layout channel associated with the particular gate track. Thus, a particular gate level feature can be defined substantially anywhere within a particular gate level feature layout channel as long as the gate electrode portion of the particular gate level feature is gated corresponding to a particular gate level layout feature The center of the pole electrode track, as long as the particular gate level feature meets the design rule spacing with respect to other gate level features in adjacent gate level layout channels. Furthermore, physical contact between gate level features defined in the gate level feature channels associated with adjacent gate electrode tracks is not permitted.

The gate level feature 7001 is defined within the gate level feature layout channel 70-5A associated with the gate electrode track 70-1A. The gate electrode portion of the gate level feature 7001 is substantially at the center of the gate electrode track 70-1A. In addition, the non-gate electrode portion of the gate level feature 7001 maintains a design regular spacing specification wherein the gate level features 7002 and 7003 are defined within adjacent gate level feature layout channels 70-5B. Similarly, gate level features 7002-7008 are defined within their respective gate level feature layout channels, and their gate electrode portions are centered on the gate electrode tracks corresponding to their respective gate level feature layout channels. In addition, it should be understood that the gate level features 7002-7008 each maintain a design rule spacing specification, wherein the gate level features are defined within adjacent gate level feature layout channels and avoid adjacent gates. The physical contact of any additional gate-level features defined within the hierarchical feature layout channel.
一閘極電極係對應在一擴散結構上方(亦即是擴散鰭部上方)延伸的一各自的閘極階層特徵的一部份,其中將各自的閘極階層特徵整體地定義於一閘極階層特徵佈局通道之內。在沒有物理性接觸在相鄰閘極階層特徵佈局通道之內所定義的另一閘極階層特徵的狀況下,各閘極階層特徵係定義在其閘極階層特徵佈局通道之內。如圖70B的例示閘極階層特徵佈局通道70-5A至70-5E所描述,各閘極階層特徵佈局通道係與一特定閘極電極軌道相關聯,且對應一佈局區域,該佈局區域沿著該特定閘極電極軌道延伸,且在自該特定閘極電極軌道至相鄰閘極電極軌道或佈局邊界外側的一虛擬閘極電極軌道任一者之其中最接近者的各個相反方向上垂直向外延伸。A gate electrode corresponds to a portion of a respective gate level feature extending above a diffusion structure (ie, above the diffusion fin), wherein the respective gate level features are integrally defined at a gate level Within the feature layout channel. In the absence of physical contact with another gate-level feature defined within adjacent gate-level feature layout channels, each gate-level feature is defined within its gate-level feature layout channel. As depicted in the illustrated gate level feature layout channels 70-5A through 70-5E of Figure 70B, each gate level feature layout channel is associated with a particular gate electrode track and corresponds to a layout area along which the layout area The particular gate electrode track extends vertically in each of the opposite directions of the closest one of the virtual gate electrode tracks from the particular gate electrode track to the adjacent gate electrode track or outside of the layout boundary Extend outside.
若干閘極階層特徵可具有一個以上接觸頭部(contact head)部分,其定義在沿其長度的任何數量的位置處。一特定閘極階層特徵的接觸頭部部分係定義成具有足夠尺寸的高度和寬度的閘極階層特徵區段,以容納閘極接觸窗結構。在這個實例中,「寬度」係在垂直於該特定閘極階層特徵的閘極電極軌道的方向上橫越基板而加以定義,且「高度」係在平行於該特定閘極階層特徵的閘極電極軌道的方向上橫越基板而定義。取決於在一元件之內閘極階層特徵的定向,閘極階層特徵寬度和高度可對應或可不對應元件寬度W及元件高度H。應瞭解的是,一閘極階層特徵的接觸頭部,當自上方觀察,可由實質上任何佈局形狀加以定義,該佈局形狀包含正方形或矩形。此外,取決於佈局需求和電路設計,一閘極階層特徵的一特定接觸頭部部分可具有或可不具有定義於其上方的一閘極接觸窗。A number of gate level features may have more than one contact head portion defined at any number of locations along its length. The contact head portion of a particular gate level feature is defined as a gate level feature segment having a height and width of sufficient size to accommodate the gate contact window structure. In this example, the "width" is defined across the substrate in a direction perpendicular to the gate electrode track of the particular gate level feature, and the "height" is at the gate parallel to the particular gate level feature. The direction of the electrode track is defined across the substrate. Depending on the orientation of the gate level features within a component, the gate level feature width and height may or may not correspond to component width W and component height H. It will be appreciated that the contact head of a gate level feature, as viewed from above, may be defined by substantially any layout shape comprising a square or a rectangle. Moreover, depending on the layout requirements and circuit design, a particular contact head portion of a gate level feature may or may not have a gate contact window defined above it.
揭露於此處的若干實施例的一閘極階層係定義成一受限制的閘極階層,如上所述。該等閘極階層特徵其中若干形成電晶體裝置的閘極電極。該等閘極階層特徵的其他者可形成延伸於該閘極階層之內二點之間的傳導區段。此外該等閘極階層特徵的其他者可相對於積體電路操作無功能。應理解的是,無論功能,在沒有物理性接觸由相鄰閘極階層特徵佈局通道所定義的其他閘極階層特徵的狀況下,各閘極階層特徵係定義成在其各自閘極階層特徵佈局通道之內延伸通過該閘極階層。A gate hierarchy of several embodiments disclosed herein is defined as a restricted gate level, as described above. Some of the gate level features form the gate electrode of the transistor device. Others of the gate level features may form a conductive section extending between two points within the gate level. In addition, the other of the gate level features may be non-functional with respect to the integrated circuit operation. It should be understood that regardless of function, in the absence of physical contact with other gate-level features defined by adjacent gate-level feature layout channels, each gate-level feature is defined as a feature layout at its respective gate level. The gate extends through the gate level.
在若干實施例中,閘極階層特徵係定義成提供有限數量的受控制的佈局形狀對形狀微影交互作用,其在製造和設計過程中可精確地加以預測和予以最佳化。在這個實施例中,閘極階層特徵係定義成用以避免會在佈局之內引入不利的微影交互作用的佈局形狀對形狀空間關係,該不利的微影交互作用無法準確地加以預測且不具高度可能性加以減輕。然而,應理解的是,當對應的微影交互作用係可預測的且可控制的,在閘極階層特徵的閘極階層佈局通道之內閘極階層特徵方向上的變化係可接受的。In several embodiments, the gate level feature is defined to provide a limited number of controlled layout shape-to-shape lithography interactions that can be accurately predicted and optimized during manufacturing and design. In this embodiment, the gate level feature is defined to avoid layout shape-to-shape spatial relationships that would introduce unfavorable lithographic interactions within the layout, which unpredictable lithographic interactions cannot be accurately predicted and High probability is alleviated. However, it should be understood that when the corresponding lithographic interaction is predictable and controllable, variations in the direction of the gate level feature within the gate level layout channel of the gate level feature are acceptable.
應理解的是,無論功能,閘極階層特徵每一者係定義成,沒有沿著一特定閘極電極軌道的閘極階層特徵係建構成自閘極階層之內直接連接至沿著的不同閘極電極軌道所定義的另一閘極階層特徵而沒有利用非閘極階層特徵。此外,配置於與不同閘極電極軌道相關聯的不同閘極階層佈局通道之內的閘極階層特徵之間的各接線,係製作成穿過可定義於較高內連線階層的一個以上非閘極階層特徵,亦即是穿過閘極階層上方一或多內連線階層,或藉由在閘極階層或於閘極階層下方的局部內連線特徵所製作。It should be understood that regardless of function, the gate level features are each defined such that the gate level features of a particular gate electrode track are not directly connected to each other along the gate from the gate level. Another gate-level feature defined by the pole electrode track does not utilize non-gate-level features. In addition, the wires between the gate-level features disposed within different gate-level layout channels associated with different gate electrode tracks are made to pass through more than one non-definitely defined at a higher interconnect level The characteristics of the gate level, that is, one or more interconnect levels above the gate level, or by local interconnect features at the gate level or below the gate level.
