典型地及較佳地,多晶碳氧矽前驅物調配物最初為液體。液體前驅物經固化成固體或半固體SiOC。固體或半固體SiOC隨後熱解成陶瓷SiOC,其隨後轉化成SiC。Typically and preferably, the polycrystalline silicon oxycarbide precursor formulation is initially a liquid. The liquid precursor is cured into solid or semi-solid SiOC. The solid or semi-solid SiOC is then pyrolyzed to ceramic SiOC, which is then converted to SiC.

碳化矽通常在真空下,在高於約1,700℃至1,800℃之溫度下不具有液相而替代地其昇華。轉向第17圖,提供SiC之分壓曲線之圖表。典型地,在工業及商業應用中,建立各種條件以便在約2,500℃及高於此之溫度下發生昇華。當碳化矽昇華時,其典型地形成由矽及碳之若干不同物質組成的蒸汽。通常,咸信溫度決定矽碳蒸汽中的該些不同組分之比率。Silicon carbide generally does not have a liquid phase but instead sublimates it under vacuum at temperatures above about 1,700°C to 1,800°C. Turning to Figure 17, a graph of the partial pressure curve for SiC is provided. Typically, in industrial and commercial applications, conditions are established so that sublimation occurs at temperatures of about 2,500°C and above. When silicon carbide sublimes, it typically forms a vapor consisting of several different species of silicon and carbon. In general, it is believed that the temperature determines the ratio of these different components in the silicon carbide vapor.

然而,本發明尤其提供預選及控制存在於矽碳蒸汽中的例如Si、C、SiC、Si 2C及SiC 2之不同物質之比率的能力。因此,除溫度之外,本發明允許控制起始材料(例如SiC之圓片)中及其中矽碳蒸汽作為例如晶體之固體沉積以生長例如胚晶的表面中及該起始材料與該表面之間的蒸汽中之矽碳物質。氣相沉積製程中的此矽碳蒸汽可稱為「通量」。 In particular, however, the present invention provides the ability to preselect and control the ratios of different species such as Si, C, SiC, Si2C and SiC2 present in the silicon carbon vapor. Thus, in addition to the temperature, the present invention allows the control of the starting material (e.g. a wafer of SiC) and in the surface in which the silicon carbon vapor is deposited as a solid such as a crystal to grow, e.g. Silicon carbon substances in the steam between. This SiC vapor in the vapor deposition process may be referred to as "flux".

胚晶之較佳實施例為單晶且僅具有單一多型體。應理解,本說明書亦設想具有多個多型體、具有多個晶體、及兩者兼有的胚晶之實施例。A preferred embodiment of an embryo crystal is single crystal and has only a single polytype. It should be understood that this description also contemplates embodiments having multiple polytypes, having multiple crystals, and embryocrystals of both.

理論上,例如,藉由相對於多晶碳氧矽衍生SiC中或用作起始材料之空間形體中存在的矽之量控制存在的碳之量,通量中存在的Si及C之量及物質可得以預定及控制。另外,及例如,藉由以受控方式使多晶碳氧矽衍生SiC之多孔性、空間形體之多孔性及兩者變化,通量之量、通量形成之速率、及通量中存在的矽及碳之物質可得以預定及控制。Theoretically, the amount of Si and C present in the flux and Substances can be predetermined and controlled. Additionally, and for example, by varying the porosity of polycrystalline silicon oxycarbide-derived SiC, the porosity of the spatial form, and both in a controlled manner, the amount of flux, the rate of flux formation, and the presence of flux in the flux The substances of silicon and carbon can be predetermined and controlled.

起始材料或起始圓片中存在的,例如,過量(比化學計量更多的碳,該化學計量亦即,1比1、矽比碳)、欠缺(比化學計量更少的碳)及化學計量的碳之量可得以預定。以此方式,起始材料或空間形體,例如,圓片中的碳之量可得以設定或建立。此量可例如藉由以下方式建立:(i)使用不同的黏合劑來形成空間形體;(ii)具有SiC材料之層,該SiC材料具有存在的不同預定量之碳;(iii)在SiC之空間形體中具有區帶,該SiC具有存在的不同預定量之碳;及(iv)該些方式之組合及變化,以及以預定方式控制起始材料中存在的碳之量。進一步,藉由控制及預定起始材料中碳對矽之比率,可在通量中控制及預定該些比率。Excess (more carbon than stoichiometric, i.e., 1 to 1, silicon to carbon), deficiency (less carbon than stoichiometric) present in the starting material or starting wafer, for example, The stoichiometric amount of carbon can be predetermined. In this way, a starting material or spatial form, eg, the amount of carbon in a wafer can be set or established. This amount can be established, for example, by: (i) using different binders to form the spatial features; (ii) having a layer of SiC material with a different predetermined amount of carbon present; (iii) between the SiC having zones in the spatial form, the SiC having different predetermined amounts of carbon present; and (iv) combinations and variations of these, and controlling the amount of carbon present in the starting material in a predetermined manner. Further, by controlling and pre-determining the ratio of carbon to silicon in the starting material, these ratios can be controlled and pre-determined in throughput.

本發明提供用於胚晶之生長,例如,SiC之氣相沉積以形成SiC之單晶胚晶的方法及製程之實施例,該單晶胚晶在該胚晶之面處提供極平坦,例如,具有有限量之曲率或弧度。胚晶之極平坦輪廓係主要地藉由使用置放於氣相沉積設備中的SiC圓片之預選形體來達成。預選形體係配置來以便在氣相沉積製程期間,通量之區域及彼區域中之流動在整個胚晶生長製程期間保持恆定。以此方式,在SiC生長時沉積在胚晶之面上的SiC之速率及量在胚晶生長製程期間保持一致及均勻。因此,例如,在生長6吋直徑胚晶中,通量流動之面積將為28.27吋 2,且跨於彼區域流動的SiC之流動速率及量將在胚晶之生長期間跨於彼整個區域為均勻的,例如,3吋長度胚晶、4吋長度胚晶等等。正如在製程期間在圓片內的可利用於昇華改變之SiC之量及位置,圓片之形體以保持通量之流動跨於直接相鄰於胚晶之面的區域均勻的方式導引通量,例如,「方向性通量」。提供方向性通量的形體之實例將為第4A圖-第4F圖、及第5A圖-第5F圖之實施例。 The present invention provides embodiments of methods and processes for the growth of an embryo, e.g., vapor deposition of SiC to form a single crystal embryo of SiC that provides an extremely flat surface at the face of the embryo, such as , has a finite amount of curvature or arc. The extremely flat profile of the embryo crystal is mainly achieved by using a preselected shape of the SiC wafer placed in the vapor deposition equipment. The pre-shape system is configured so that during the vapor deposition process, the region of flux and the flow in that region remains constant throughout the embryonic crystal growth process. In this way, the rate and amount of SiC deposited on the face of the embryo crystal as SiC grows remains consistent and uniform during the embryo crystal growth process. Thus, for example, in growing a 6 inch diameter embryo crystal, the area of flux flow would be 28.27 inches , and the flow rate and amount of SiC flowing across that area would be Uniform, eg, 3 inch length embryo crystals, 4 inch length embryo crystals, etc. As the amount and location of SiC available for sublimation changes within the wafer during processing, the shape of the wafer directs the flux in a manner that keeps the flow of flux uniform across the region immediately adjacent to the face of the embryo crystal. , for example, Directional Flux. Examples of features that provide directional flux would be the embodiments of Figures 4A-4F, and Figures 5A-5F.

在實施例中,通量遍及生長製程不維持恆定。因此,在此等實施例中,通量跨於生長面之分佈以預定方式管理,例如,控制來提供胚晶或生長面之區域的預定生長。因此,例如,在生長之稍後階段,通量可以預定方式經導引以補償已在胚晶之生長中發生的不均勻性。在此實例中,其中通量在生長之較早階段中較多的區域在生長之稍後階段中具有較少的通量;類似地,其中通量在生長之較早階段中較少的區域在生長之稍後階段中具有較多的通量。以此方式,最終胚晶生長面最小化胚晶面之曲率或最大化胚晶面之曲率半徑。In an embodiment, the flux is not maintained constant throughout the growth process. Thus, in such embodiments, the distribution of flux across the growth surface is managed in a predetermined manner, eg, controlled to provide a predetermined growth of the embryonic crystal or region of the growth surface. Thus, for example, at a later stage of growth, the flux can be directed in a predetermined manner to compensate for inhomogeneities that have occurred in the growth of the embryo crystal. In this example, regions where flux is more in earlier stages of growth have less flux in later stages of growth; similarly, regions where flux is less in earlier stages of growth There is more flux in later stages of growth. In this way, the final embryo crystal growth plane minimizes the curvature of the embryo crystal face or maximizes the radius of curvature of the embryo crystal face.

在實施例中,受控通量及更佳地方向通量之使用可提供4吋胚晶,其具有將為至少約6吋、至少約8吋、至少約20吋、至少約60吋、及接近無限(亦即,平坦),以及該些值範圍內之所有值的曲率半徑(亦即,曲率之倒數)。在6吋胚晶之實施例中,曲率半徑(亦即,曲率之倒數)將為至少約10吋、至少約15吋、至少約25吋、至少約60吋、及接近無限(亦即,平坦),以及該些值範圍內之所有值。在實施例中,胚晶面之曲率半徑為胚晶之長度的至少2倍、胚晶之長度的至少5倍、胚晶之長度的至少10倍、及胚晶之長度的至少25倍,多至且包括其中胚晶面為平坦之情況,以及此範圍內之所有值。轉向第21圖,為胚晶2100之示意圖。胚晶2100具有藉由箭頭2102展示的長度及藉由箭頭2103展示的寬度或直徑。胚晶具有面(例如生長面) 2101,其具有彎曲表面2101a。彼表面2101a之曲率半徑係藉由虛線2104展示。因此,將為胚晶2100之曲率半徑的表面2101a之曲率半徑等於圓弧之半徑2104,該圓弧最佳地近似面2101之曲線。In an embodiment, the use of controlled flux and more preferably directional flux can provide a 4 inch embryo crystal having a size that will be at least about 6 inches, at least about 8 inches, at least about 20 inches, at least about 60 inches, and near infinity (ie, flat), and the radius of curvature (ie, the reciprocal of curvature) for all values within these ranges of values. In embodiments of a 6 inch embryo, the radius of curvature (i.e., the inverse of curvature) will be at least about 10 inches, at least about 15 inches, at least about 25 inches, at least about 60 inches, and nearly infinite (i.e., flat ), and all values within those values. In an embodiment, the radius of curvature of the embryo crystal face is at least 2 times the length of the embryo crystal, at least 5 times the length of the embryo crystal, at least 10 times the length of the embryo crystal, and at least 25 times the length of the embryo crystal, at least Up to and including the case where the embryonic plane is flat, and all values within this range. Turning to FIG. 21 , it is a schematic diagram of an embryo crystal 2100 . Embryocrystal 2100 has a length shown by arrow 2102 and a width or diameter shown by arrow 2103 . The embryo crystal has a face (eg, growth face) 2101 with a curved surface 2101a. The radius of curvature of the surface 2101 a is shown by dashed line 2104 . Thus, the radius of curvature of the surface 2101a which will be the radius of curvature of the embryonic crystal 2100 is equal to the radius 2104 of the arc which best approximates the curve of the surface 2101 .

在實施例中,通量可以壓力以及溫度操縱。對於給定生長溫度,生長可藉由增加腔室壓力減慢。最快速率係典型地處於「完全」真空下(例如,真空泵開啟且保持腔室壓力盡可能低)。因此,例如,為以400 μm/hr生長胚晶,該生長可在完全真空之P1下處於溫度T1,或可處於溫度T2>T1,並具有幾mBar至幾十mBar之氬分壓(P2>P1)。以此方式,通量及生長速率可經「調諧」。In an embodiment, the flux can be manipulated by pressure as well as temperature. For a given growth temperature, growth can be slowed by increasing the chamber pressure. The fastest rates are typically at "full" vacuum (eg, vacuum pump on and chamber pressure kept as low as possible). Thus, for example, to grow an embryo at 400 μm/hr, the growth can be at temperature T1 under P1 in full vacuum, or can be at temperature T2>T1 with an argon partial pressure of a few mBar to tens of mBar (P2> P1). In this way, flux and growth rate can be "tuned."

在實施例中,聚合物衍生SiC在胚晶中賦予較好的多型體穩定性,此歸因於隨時間更一致的通量組成。此實施例,亦即,受控多型體穩定性對胚晶製造商而言有價值且為重要的,因為多型體變換中等生長僅意指胚晶之一部分為原始多型體,其典型地不利地影響電子性質,從而影響由其構建的晶片之裝置效能。In an embodiment, polymer derived SiC confers better polytype stability in the embryo due to a more consistent flux composition over time. This embodiment, i.e., controlled polytype stability is valuable and important to the embryo crystal manufacturer, because the polytype transformation medium growth only means that a part of the embryo crystal is the original polytype, which typically It can adversely affect the electronic properties, thereby affecting the device performance of chips built therefrom.

本發明提供「調諧」通量之能力,且因此提供經由使用本發明的聚合物衍生SiC及預定圓片形體來賦能有效性較小的氣相沉積設備以產生處於實質上改良品質、數量、生產率及該些者之組合及變化的能力。以此方式,較低品質氣相沉積設備之效能可顯著地改良,且經改良至其中其滿足或超過較高品質氣相沉積設備之點。因此,例如,本發明之形體及其調諧通量之能力提供不具有任何機械修改的現存氣相沉積設備生產胚晶之能力,該等胚晶具有:少10%之缺陷,具有少20%之缺陷,具有少50%之缺陷,具有少100%之缺陷,及甚至更少缺陷;生產胚晶之能力,該等胚晶係以2倍速率、以3倍速率、及以4倍速率及更大速率生產;且生產胚晶之能力,該等胚晶具有較平的面,亦即,更平坦的,平至少2倍、平至少3倍、平至少4倍、及更平的,以及該些值範圍內之全部;及該些改良之組合及變化,包括該些一般改良中之所有三者,亦即,較少缺陷、增加的速率、及增加的平坦度。調諧通量提供不具有任何機械修改的氣相沉積設備對給定時間段而言生產1.5倍、2倍、3倍、或更多倍胚晶之能力,且更佳地具有本文闡述的改良品質特徵之一或多者,包括實質上較少的缺陷及大體上較高的品質。The present invention provides the ability to "tune" the flux and thus provide the ability to enable less effective vapor deposition equipment by using the polymer-derived SiC of the present invention and predetermined wafer shapes to produce substantially improved quality, quantity, Productivity and the ability to combine and vary these. In this way, the performance of lower quality vapor deposition equipment can be significantly improved, and improved to the point where it meets or exceeds higher quality vapor deposition equipment. Thus, for example, the morphology of the present invention and its ability to tune flux provides the ability, without any mechanical modification, of existing vapor deposition equipment to produce embryo crystals with: 10% fewer defects, with 20% fewer Defects, with 50% fewer defects, with 100% fewer defects, and even fewer defects; the ability to produce embryo crystals at 2 times the rate, at 3 times the rate, and at 4 times the rate and more High rate production; and the ability to produce embryo crystals that have a flatter face, i.e., flatter, at least 2 times flatter, at least 3 times flatter, at least 4 times flatter, and flatter, and the all within these ranges of values; and combinations and variations of such improvements, including all three of these general improvements, namely, fewer defects, increased speed, and increased flatness. Tuned throughput provides the ability of a vapor deposition apparatus without any mechanical modifications to produce 1.5x, 2x, 3x, or more embryo crystals for a given time period, and preferably with the improved qualities set forth herein One or more of the characteristics, including substantially fewer defects and generally higher quality.

轉向第18圖,展示用於生長SiC晶體、結晶結構及胚晶的設備之示意橫截面表示。氣相沉積裝置1800為具有側壁1808、底部或底部壁1809、及頂部或頂部壁1810之容器。壁1808、1809、1810可具有埠1806、1807、1805,其可為開口、噴嘴、閥,其可控制或允許氣體流入及流出裝置1800。裝置1800與其加熱元件1804相關聯。加熱元件可經配置及操作以在裝置1800內部提供單一溫度區帶,或多個溫度區帶。在裝置1800內部,存在圓片1801,其係由已成形在一起成為空間形體之SiC粒子製成。Turning to Figure 18, there is shown a schematic cross-sectional representation of an apparatus for growing SiC crystals, crystalline structures and embryo crystals. Vapor deposition apparatus 1800 is a container having sidewalls 1808 , a bottom or bottom wall 1809 , and a top or top wall 1810 . Walls 1808 , 1809 , 1810 may have ports 1806 , 1807 , 1805 , which may be openings, nozzles, valves, which may control or allow gas to flow into and out of device 1800 . The device 1800 is associated with its heating element 1804 . The heating element may be configured and operated to provide a single temperature zone, or multiple temperature zones, within device 1800 . Inside the device 1800 there is a wafer 1801 made of SiC particles that have been shaped together into a spatial form.

圓片1801可具有預定多孔性及密度。SiC粒子可具有預定多孔性及密度。SiC粒子係保持在一起,較佳地藉由黏合劑保持在一起。圓片1801可為富碳、貧碳、或化學計量的。圓片1801可具有為富碳、貧碳、或化學計量的區帶或層。較佳地,SiC粒子為SiOC聚合物衍生SiC。非聚合物衍生SiC亦可用作圓片之部分或全部。圓片1801具有藉由箭頭1821展示的高度及橫截面或直徑1820。圓片1801具有上表面或頂表面1823及底表面1824。在此實施例中,圓片1801係展示為平坦頂部及底部圓柱體;應瞭解,藉由本說明書涵蓋的任何空間形體可用於裝置1800。The wafer 1801 may have a predetermined porosity and density. The SiC particles may have a predetermined porosity and density. The SiC particles are held together, preferably by a binder. Wafer 1801 may be carbon rich, carbon lean, or stoichiometric. Wafer 1801 may have zones or layers that are carbon rich, carbon lean, or stoichiometric. Preferably, the SiC particles are SiOC polymer derived SiC. Non-polymer derived SiC can also be used as part or all of the wafer. Wafer 1801 has a height and a cross-section or diameter 1820 shown by arrow 1821 . Wafer 1801 has an upper or top surface 1823 and a bottom surface 1824 . In this embodiment, wafer 1801 is shown as a flat top and bottom cylinder; it should be understood that any spatial shape encompassed by this description may be used for device 1800 .

在裝置1800之頂部1810處,存在晶種1802,其具有表面1802a。晶種1802具有橫截面或直徑1822及高度1823。在一些實施例中,晶種可安裝在可移動平臺1803上以調整表面1802a與表面1823之間的距離。At the top 1810 of the device 1800, there is a seed crystal 1802, which has a surface 1802a. Seed 1802 has a cross-section or diameter 1822 and a height 1823 . In some embodiments, seeds can be mounted on movable platform 1803 to adjust the distance between surface 1802a and surface 1823 .

圓片1801之直徑1820可大於、小於、或與晶種1802之直徑1822相同。The diameter 1820 of the wafer 1801 may be larger, smaller, or the same as the diameter 1822 of the seed crystal 1802 .

在操作中,加熱元件1804升高圓片1801之溫度至SiC昇華之點。此昇華引起具有矽及碳之各種物質的氣體之形成。此氣體,亦即,通量存在於表面1802a與1823之間的區域1850。取決於多孔性或其他因素,通量亦可存在於圓片1801內。通量在裝置1800中上升穿過區域1850,其中通量將SiC沉積在表面1802a上。表面1802a必須保持在一溫度下,該溫度足夠冷以引起氣態矽碳物質沉積出其表面以形成SiC晶體。以此方式,晶種1802係藉由連續地在其表面上在多型體匹配定向上添加已生長的SiC來生長成胚晶。因此,除非藉由裝置1803 (其以完全收縮位置展示)調整,否則在胚晶之生長期間,表面1803將朝向底部1809生長,且因此,減少表面1802a與底部1809之間的距離。通量之形體可用於在氣相沉積製程期間在圓片內產生預定溫度差。此預定溫度差可解決、減少且消除鈍化之有害效應,此為其中物質在減少或防止Si-C蒸汽形成之製程期間堆積在圓片中的狀況。In operation, heating element 1804 raises the temperature of wafer 1801 to the point where SiC sublimates. This sublimation causes the formation of gases with various species of silicon and carbon. This gas, ie flux, exists in region 1850 between surfaces 1802a and 1823 . Flux may also exist within the wafer 1801 depending on porosity or other factors. Flux rises in device 1800 through region 1850, where the flux deposits SiC on surface 1802a. Surface 1802a must be maintained at a temperature that is cold enough to cause gaseous silicon carbon species to deposit out of its surface to form SiC crystals. In this way, the seed crystal 1802 is grown into an embryo crystal by successively adding grown SiC on its surface in a polytype-matched orientation. Therefore, unless adjusted by means 1803 (shown in a fully retracted position), during growth of the embryo, surface 1803 will grow towards bottom 1809, and thus, reduce the distance between surface 1802a and bottom 1809. Flux profiles can be used to create predetermined temperature differentials within a wafer during a vapor deposition process. This predetermined temperature difference can address, reduce and eliminate the deleterious effects of passivation, a condition in which species build up in the wafer during a process that reduces or prevents Si—C vapor formation.

理論上,昇華及沉積之製程在源材料自身之空間形體內部發生且遵循源材料中自然產生之熱梯度,或該熱梯度可藉由圓片之形體決定。在實施例中,黏合材料可較佳地保持存在且在昇華溫度期間維持圓片之形體及完整性,並因此在SiC之昇華溫度下或低於該昇華溫度不會昇華。此熱梯度典型地自外部朝向內部且向上。理論上,材料持續地昇華且再沉積在相鄰粒子上且以此方式經歷Si-C物質之回流或固態「分餾」或「分昇華」。Theoretically, the processes of sublimation and deposition take place within the spatial shape of the source material itself and follow the thermal gradients naturally occurring in the source material, or this thermal gradient can be determined by the shape of the wafer. In embodiments, the adhesive material may preferably remain present and maintain the shape and integrity of the wafer during the sublimation temperature, and thus will not sublime at or below the sublimation temperature of SiC. This thermal gradient is typically from the outside towards the inside and upwards. Theoretically, the material is continuously sublimated and redeposited on adjacent particles and in this way undergoes reflux or solid state "fractionation" or "subsublimation" of the Si-C species.

進一步在理論上,在實施例中,空間形體及其預定梯度可允許一些較重雜質俘獲在生長腔室之底部中於圓片內,而較輕元素連同Si-C蒸汽一起昇華且運送至晶種。此理論上提供在製程中的預定時間具有摻雜劑或其他添加劑釋放;以及緩和雜質之潛在不利效應的能力。應瞭解,較佳地將超純材料用於圓片中。Further in theory, in embodiments, the spatial shape and its predetermined gradient may allow some heavier impurities to be trapped within the wafer in the bottom of the growth chamber, while lighter elements are sublimated and transported to the wafer along with the Si—C vapor. kind. This theoretically provides the ability to have dopants or other additives released at predetermined times in the process; and to mitigate the potential adverse effects of impurities. It will be appreciated that ultrapure materials are preferably used in the wafers.

在實施例中,圓片提供針對給定溫度更一致的通量形成速率。形體可經特製以提供遍及形體之更均勻溫度,從而允許該形體之較高體積分數一次性昇華,在晶種/蒸汽界面處在給定溫度下比標準粉末堆或粉末之圓柱形形體驅動更高速率之通量。因此,需要較低溫度生長製程之多型體之生長將因而不受限於減慢的生長速率。In an embodiment, the wafer provides a more consistent rate of flux formation for a given temperature. A body can be tailored to provide a more uniform temperature throughout the body, allowing a higher volume fraction of the body to sublime at once, driving more at a given temperature at the seed/vapor interface than a standard powder stack or cylindrical body of powder. High rate throughput. Thus, the growth of polytypes requiring lower temperature growth processes will thus not be limited by a reduced growth rate.

昇華速率係以公克/小時來量測。通量係以公克/cm 2-hr (亦即,材料通過區域之速率)給出。因此,關鍵面積為相應於胚晶生長面之即時表面面積的通量面積,例如,其中SiC正在沉積的胚晶之面。典型地,通量面積及胚晶面之面積約相同的,且該些面積典型地稍微小於氣相沉積設備之生長腔室之橫截面積。 Sublimation rate is measured in grams per hour. Flux is given in grams/cm2 - hr (ie, the rate at which material passes through a region). Thus, the critical area is the flux area corresponding to the immediate surface area of the embryonic growth face, eg, the face of the embryonic crystal where SiC is being deposited. Typically, the flux area and the area of the embryo plane are about the same, and these areas are typically slightly smaller than the cross-sectional area of the growth chamber of the vapor deposition apparatus.

出於計算及此分析之目的,出於計算方便,假定生長腔室之橫截面積與通量面積及胚晶面之面積相同。因此,胚晶之生長速率(μm/hr)可亦等於穿過胚晶表面之區域(cm 2)的蒸汽通量—μm/hr—g/hr (完全緻密SiC之密度為3.21 g/cc)。現場量測可經由X射線成像或X射線電腦斷層攝影(computed tomography; CT)來進行。另外,平均生長速率可藉由在生長之前/之後稱重胚晶來測定。 For the purposes of the calculations and this analysis, for computational convenience, it is assumed that the cross-sectional area of the growth chamber is the same as the flux area and the area of the embryo face. Therefore, the growth rate of the embryo crystal (μm/hr) can also be equal to the vapor flux through the area (cm 2 ) of the surface of the embryo crystal—μm/hr—g/hr (the density of fully dense SiC is 3.21 g/cc) . The on-site measurement can be performed by X-ray imaging or X-ray computed tomography (CT). Alternatively, the average growth rate can be determined by weighing the embryo crystals before/after growth.

典型的商業生長速率在200-500 μm/hr範圍。本發明之製程及空間形體之實施例遠超過該些現存的商業速率,而同時提供相等及優越品質之胚晶。例如,本發明之實施例可具有在高溫及低壓下的約550至約1,1000 μm/hr、約800至約1,000 μm/hr、約900至約1,100 μm/hr、約700 μm/hr、約 800 μm/hr、約 900 μm/hr、約 1,000 μm/hr、1,100 μm/hr之生長速率。涵蓋較高速率且亦可使用較慢速率,以及該些範圍內的所有速率。Typical commercial growth rates are in the range of 200-500 μm/hr. The process and spatial form embodiments of the present invention far exceed these existing commercial rates while providing embryo crystals of equal and superior quality. For example, embodiments of the present invention may have about 550 to about 1,1000 μm/hr, about 800 to about 1,000 μm/hr, about 900 to about 1,100 μm/hr, about 700 μm/hr, Growth rates of about 800 μm/hr, about 900 μm/hr, about 1,000 μm/hr, and 1,100 μm/hr. Higher rates are contemplated, and slower rates may also be used, and all rates within these ranges.

通常,生長速率係藉由1)溫度及2)供氣壓力(Ar、N 2等等)來驅動。更大氣體壓力稀釋在晶種處及胚晶之面處的矽碳物質之蒸汽壓,且針對任何給定溫度減慢生長速率。因此,壓力可用於「撥入(dial-in)」生長速率。第19圖之圖表展示本發明之多晶碳氧矽衍生SiC之實施例(具有1.4-1.45 g/cc填積密度之圓片)的生長速率。 Typically, the growth rate is driven by 1) temperature and 2) gas supply pressure (Ar, N2, etc.). Greater gas pressure dilutes the vapor pressure of the silicon carbon species at the seed and at the face of the embryo crystal and slows the growth rate for any given temperature. Thus, pressure can be used to "dial-in" the growth rate. Figure 19 is a graph showing the growth rate for embodiments of polycrystalline silicon oxycarbide derived SiC of the present invention (wafers with a packing density of 1.4-1.45 g/cc).

根據第19圖之圖表,可見本發明之實施例不展現鈍化。其不為自我限制的,且其為無鈍化的。該些實施例提供超過氣相沉積製程中SiC起始材料之現存來源的顯著改良及優點。SiC之該些現存來源具有自我限制效應,其中通量產生之速率隨時間推移降低,因為起始材料上之表面效應約束或抑制昇華。此自我限制效應通常稱為鈍化,但亦可稱為來源耗盡、石墨化、或碳化。From the graph of Figure 19, it can be seen that the embodiments of the present invention do not exhibit passivation. It is not self-limiting, and it is non-passivating. These embodiments provide significant improvements and advantages over existing sources of SiC starting material in vapor deposition processes. These existing sources of SiC have a self-limiting effect, where the rate of flux generation decreases over time because surface effects on the starting material confine or inhibit sublimation. This self-limiting effect is commonly referred to as passivation, but may also be referred to as source depletion, graphitization, or carbonization.

因此,給定恆定溫度,空間形體之實施例,例如,圓片可在胚晶生長之整個操作期間維持一致的通量產生速率,例如,恆定通量產生速率,該胚晶包括具有約4吋至約10吋直徑、約6吋至約8吋直徑、約4吋直徑、約6吋直徑、約8吋直徑及較大及較小直徑,以及該些值之範圍內的所有直徑之胚晶。給定用於整個胚晶生長製程之恆定溫度,空間形體之實施例可將通量產生速率,及因此胚晶生長速率維持在恆定速率、恆定速率、具有小於約0.001%改變之速率、具有小於約0.01%改變之速率、具有小於約1%改變之速率、具有小於約5%改變之速率、具有小於約20%改變之速率、具有約0.001%改變至約15%改變之速率、具有約0.01%改變至約5%改變之速率、及在胚晶之生長期間該些者之組合及變化,以及該些值之範圍內的所有值。在實施例中,在恆定溫度下通量形成速率保持在:其最大速率之約99.999%至約60%;其最大速率之約99%至約95%;其最大速率之約99.99%至約80%;其最大速率之約99%至約70%;其最大速率之約95%至約70%;其最大速率之約99%至約95%;及在胚晶之生長期間該些者之組合及變化,以及該些百分比範圍內之所有值。Thus, given a constant temperature, an embodiment of a spatial body, e.g., a wafer, can maintain a consistent rate of flux generation, e.g., a constant rate of flux generation, during the entire operation of the growth of an embryonic crystal comprising about 4 inches of Embryocrystals to about 10 inches in diameter, about 6 inches to about 8 inches in diameter, about 4 inches in diameter, about 6 inches in diameter, about 8 inches in diameter and larger and smaller diameters, and all diameters within the range of these values . Given a constant temperature for the entire embryo crystal growth process, embodiments of the space form can maintain the rate of flux generation, and thus the rate of embryo crystal growth, at a constant rate, a constant rate, a rate with less than about 0.001% variation, with a rate of less than A rate of change of about 0.01%, a rate of change of less than about 1%, a rate of change of less than about 5%, a rate of change of less than about 20%, a rate of change of about 0.001% to about 15%, a rate of change of about 0.01 % change to about 5% change rate, and combinations and changes of these during the growth of the embryocrystal, and all values within the range of these values. In an embodiment, the rate of flux formation at a constant temperature is maintained at: about 99.999% to about 60% of its maximum rate; about 99% to about 95% of its maximum rate; about 99.99% to about 80% of its maximum rate %; about 99% to about 70% of its maximum rate; about 95% to about 70% of its maximum rate; about 99% to about 95% of its maximum rate; and combinations of these during the growth of the embryo crystal and changes, and all values within those percentage ranges.

實施例具有獨特體密度。在實施例中,空間形體,例如,圓片係在模製製程中製成,且因此,粉末可經壓實至多至2.0 g/cc (2.0/3.21 = 62%填積分數或38%多孔性)之極高體密度。所得形體仍具有相同的起始材料粒子之高表面面積,仍允許更大重量之源材料佔據生長腔室之底部。以此方式,較大胚晶可自較高密度源材料生長。在整個生長製程期間亦保持活性的更多源材料產生較長的生長時間及因此較長、較寬、及兩者的胚晶。該些益處不管生長界面之最終形狀而存在。此亦可延長生長循環以進一步生長較大的胚晶。Embodiments have unique bulk densities. In an embodiment, a spatial form, such as a disc, is made in a molding process, and thus, the powder can be compacted up to 2.0 g/cc (2.0/3.21 = 62% fill fraction or 38% porosity ) extremely high body density. The resulting shape still has the same high surface area of the starting material particles, still allowing a greater weight of source material to occupy the bottom of the growth chamber. In this way, larger embryo crystals can be grown from higher density source materials. More source material that also remains active throughout the growth process results in longer growth times and thus longer, wider, and both embryonic crystals. These benefits exist regardless of the final shape of the growth interface. This can also extend the growth cycle to further grow larger embryo crystals.

以此方式,氣相沉積製程之循環的生長部分之容量利用可得以最大化。因此,本發明之實施例提供大大地增加現存氣相沉積設備之生長循環的容量利用之能力。典型地,在現存氣相沉積設備中,需要約10-30 hr之加熱時間(其不為生長循環之一部分)及約30-50 hr之冷卻時間(其不為生長循環之一部分)。該些非生長循環時間將僅隨較大胚晶大小(腔室及胚晶不可熱震或其可破裂)而增加。因此,若生長循環(亦即,在加熱循環期間在昇華及沉積以生長胚晶發生時的時間)延長10-20 hr之生長,則該生長循環可增加400 μm/hr之胚晶生長。此舉又顯著地賦能每一胚晶生長循環更多晶圓得以生產且減小可消耗物之成本及最終每一晶圓之製造成本。因此,本發明之實施例為實質上增加熔爐之生長持續時間容量利用之能力。In this way, capacity utilization for the growth portion of the cycle of the vapor deposition process can be maximized. Accordingly, embodiments of the present invention provide the ability to greatly increase the capacity utilization of growth cycles of existing vapor deposition equipment. Typically, in existing vapor deposition equipment, about 10-30 hr of heating time (which is not part of the growth cycle) and about 30-50 hr of cooling time (which is not part of the growth cycle) are required. These non-growth cycle times will only increase with larger embryo crystal size (the chamber and the embryo crystal cannot be thermally shocked or they can be broken). Thus, if the growth cycle (ie, the time during the heating cycle when sublimation and deposition to grow the embryo crystal occurs) is extended by 10-20 hrs of growth, the growth cycle can increase the growth of the embryo crystal by 400 μm/hr. This in turn enables significantly more wafers to be produced per embryonic growth cycle and reduces the cost of consumables and ultimately the manufacturing cost per wafer. Accordingly, embodiments of the present invention are capable of substantially increasing the growth duration capacity utilization of a furnace.

因此,在實施例中,相較於使用當前可利用的SiC源材料而言,用於具有相同直徑之胚晶的氣相沉積設備之生長循環可藉由使用本發明之聚合物衍生SiC及空間形體之實施例來增加達:約10%至約100%、約10%至約60%、約20%至約60%、約33%至約70%、至少約30%、至少約50%、至少約70%及更大,以及該些百分比範圍內之所有值。在實施例中,對於可最終自單一生長循環獲得(生長胚晶且隨後切割成具有相同厚度之晶圓)的具有相同厚度及直徑之晶圓,相較於使用當前可利用的SiC源材料而言,晶圓之數量可使用本發明之聚合物衍生SiC及空間形體之實施例增加達:約10%至約500%、約100%至約300%、約10%至約70%、約30%至約70%、至少約20%、至少約50%、至少約100%、至少約200%、至少2個晶圓、至少10個晶圓、至少20個晶圓、至少100個晶圓、至少1,000個晶圓、至少約2個至100個晶圓、至少約10個至100個晶圓、至少約50個至200個晶圓、約100個至500個晶圓、及更個,以及該些值範圍內之所有值。亦獲得自單一生長循環獲得更多晶圓之能力且得以進一步增加,因為本發明之胚晶之實施例將具有實質上比自習知SiC源材料生長的胚晶更少的缺陷,且因此將在胚晶中存在實質上更多的可使用材料來製造晶圓。此增加的晶圓生產量、及增加的胚晶生長效率、及增加的胚晶品質可進一步具有來自單一生長循環的裝置之增加產量之效應。因此,裝置之數量可增加達至少約100個、至少約200個、至少約1,000個、至少約10,000個、至少約100,000個及更多個,約100個至約10,000個、約1,000個至約30,000個、約500個至約20,000個及約20,000個至約50,000個,以及該些值範圍內之所有值。Thus, in an embodiment, the growth cycle of a vapor deposition apparatus for an embryo having the same diameter as compared to using currently available SiC source materials can be achieved by using the polymer-derived SiC and spacers of the present invention. Embodiments of the shape increase up to: about 10% to about 100%, about 10% to about 60%, about 20% to about 60%, about 33% to about 70%, at least about 30%, at least about 50%, At least about 70% and greater, and all values within those percentage ranges. In an embodiment, for wafers of the same thickness and diameter that can ultimately be obtained from a single growth cycle (growing embryo crystals and then dicing into wafers of the same thickness), compared to using currently available SiC source material In other words, the number of wafers can be increased by about 10% to about 500%, about 100% to about 300%, about 10% to about 70%, about 30% using embodiments of the polymer-derived SiC and spatial features of the present invention. % to about 70%, at least about 20%, at least about 50%, at least about 100%, at least about 200%, at least 2 wafers, at least 10 wafers, at least 20 wafers, at least 100 wafers, at least 1,000 wafers, at least about 2 to 100 wafers, at least about 10 to 100 wafers, at least about 50 to 200 wafers, about 100 to 500 wafers, and more, and All values within these ranges. The ability to obtain more wafers from a single growth cycle is also obtained and further increased because embodiments of the embryos of the present invention will have substantially fewer defects than embryos grown from conventional SiC source materials, and will therefore There is substantially more usable material in the embryonic crystal to make the wafer. This increased wafer throughput, and increased embryo crystal growth efficiency, and increased embryo crystal quality may further have the effect of increased yield of devices from a single growth cycle. Thus, the number of devices can be increased to at least about 100, at least about 200, at least about 1,000, at least about 10,000, at least about 100,000, and more, from about 100 to about 10,000, from about 1,000 to about 30,000, about 500 to about 20,000, and about 20,000 to about 50,000, and all values within these ranges.

實施例提供在預定形體中具有形體控制的能力,咸信該等形體中許多者尚未知曉,且對大型部件而言,使用現存起始材料不可獲得。置放於氣相沉積設備中作為用於胚晶生長之源材料的空間形體,例如,圓片之形體可驅動或正面地影響生長製程之許多參數以相較於習知源材料獲得較大胚晶、較高品質胚晶、較高品質晶圓、更多晶圓,及該些者之組合及變化。該些改良生長參數包括:減少來源之軸向熱梯度;來源之徑向熱梯度;增加來源之軸向熱梯度;正在昇華的源材料之表面面積,防止通量限制;較熱的內部來源溫度以提供遍及源材料之更均勻昇華;穿過源材料之快速通量及引導通量路徑(將蒸汽導引至所要位置—中心或邊緣或兩者,此尤其提供較平坦胚晶生長面)。在稍後生長階段期間將通量朝向胚晶之邊緣導引的能力賦能邊緣與中心一樣快地生長,不管來源在邊緣附近更完全地消耗。因此,最終幾何形狀不為典型的凸狀胚晶,其係藉由使用當前源材料獲得,且具有不可用於自其製造晶圓的廢胚晶材料。替代地,源材料之本發明實施例提供具有平坦面之胚晶,因此大大地增加可用於製造晶圓的胚晶之量。Embodiments provide the ability to have shape control in predetermined shapes, many of which are believed to be unknown and, for large parts, not achievable using existing starting materials. Placement in vapor deposition equipment as a spatial shape of source material for embryo growth, for example, the shape of a wafer can drive or positively affect many parameters of the growth process to obtain larger embryos compared to conventional source materials, Higher quality embryos, higher quality wafers, more wafers, and combinations and variations of these. These modified growth parameters include: reduced axial thermal gradient of the source; radial thermal gradient of the source; increased axial thermal gradient of the source; surface area of the source material being sublimated to prevent flux limitation; hotter internal source temperature To provide more uniform sublimation throughout the source material; fast flux through the source material and directing the flux path (directing the vapor to the desired location - center or edge or both, this especially provides a flatter embryonic growth surface). The ability to direct flux towards the edge of the embryonic crystal during later growth stages enables the edge to grow as fast as the center, despite sources being more completely consumed near the edge. Therefore, the final geometry is not the typical convex embryo obtained by using the current source material and having spent embryo material that is not available for making wafers from it. Alternatively, the inventive embodiments of the source material provide embryo crystals with planar faces, thereby greatly increasing the amount of embryo crystals available for wafer fabrication.

除上述之外,自具有起始材料之預定形體獲得的額外益處包括:賦能穿過視線至坩堝底部的生長面之中心之輻射加熱,從而尤其減少晶種中之徑向熱梯度且進一步咸信賦能較大胚晶(8"、10"及超過此)的生長,以及阻尼冷卻循環以減少晶體中之應力且防止開裂;相較於在相同氣相沉積設備中使用現存起始材料而言,經由更均勻的胚晶溫度及結果在胚晶上較少的熱應力而改良多型體穩定性且減少線缺陷/錯位;由於預選或決定在製程結束時不具有其從未完全地得到昇華的起始材料之能力,賦能源材料之更完全利用;藉由使大量源材料昇華以形成胚晶,且因此改良來源至胚晶產率及成本效率而減少浪費源材料。In addition to the above, additional benefits obtained from having a pre-shaped body of starting material include: enabling radiative heating across the line of sight to the center of the growth face at the bottom of the crucible, thereby reducing inter alia radial thermal gradients in the seed and further Facilitates the growth of larger embryo crystals (8", 10" and beyond), and dampens cooling cycles to reduce stress in the crystal and prevent cracking; compared to using existing starting materials in the same vapor deposition equipment In other words, improved polytype stability and reduced line defects/dislocations through more uniform embryo temperature and consequently less thermal stress on the embryo; this has never been fully achieved due to preselection or decision not to have at the end of the process The ability to sublimate starting materials enables more complete utilization of source materials; reducing waste of source materials by sublimating large quantities of source materials to form embryos, and thus improving source-to-embryo yields and cost-efficiency.

在生長前沿的胚晶之中心典型地比邊緣更冷,從而使得其更像是用於材料沉積之「槽坑(sink)」(彙集蒸汽通量之來源)。因此,理論上,若視線係穿過源材料自底部通向頂部,則自坩堝之底部的輻射將到達球狀面之中心且將其稍微升溫—甚至一至數十℃左右—從而使得中心較不像「槽坑」且允許整個晶種之更均勻溫度,從而在沿晶體的所有位置處產生更均勻通量且賦能較平坦胚晶。進一步在理論上,此開放視線形體實施例亦將允許在源材料之中心處的材料更有效地昇華且轉變成胚晶—此通常為昇華的最後地方,因為其為源材料之最冷部分且生長在其未曾耗盡之前停止。開放視線形體圓片之實施例之實例係展示在第9圖及第10圖。The center of the embryonic crystal at the growth front is typically cooler than the edges, making it more like a "sink" (a source of concentrating vapor flux) for material deposition. Therefore, in theory, if the line of sight goes from the bottom to the top through the source material, the radiation from the bottom of the crucible will reach the center of the spherical surface and heat it up slightly—even by one to tens of degrees Celsius—so that the center is less dense. Acts like a "well" and allows for a more uniform temperature across the seed, resulting in a more uniform flux and energization of a flatter embryo at all locations along the crystal. Further in theory, this open line-of-sight form embodiment would also allow the material at the center of the source material to sublimate more efficiently and transform into the embryo crystal - this is usually the last place to sublimate since it is the coldest part of the source material and Growth stops before it is depleted. Examples of embodiments of open line of sight shape wafers are shown in FIGS. 9 and 10 .

實施例提供源材料遍及空間形體之密度分佈,該空間形體係用作氣相沉積設備中之起始材料。密度之此預定分配提供超過現存源材料之若干優點及改良,包括:向形體之特定部分或區域的預定及受控熱傳導,諸如向某些區域之改良熱傳導,有限的熱傳導,以使得在生長循環之持續時間期間來源全程更均勻地消耗,且具有以受控方式維持的熱傳導,較佳地均勻熱傳導。昇華組成(亦即,由起始材料之昇華形成的蒸汽之組成,例如,通量組成)亦可改變,具有遍及循環更持續或均勻的組成,或在生長開始時更增強的組成,從而尤其提供歸因於穩定組成的較好多型體穩定性。Embodiments provide a density distribution of source materials throughout a spatial form used as a starting material in a vapor deposition apparatus. This predetermined distribution of density provides several advantages and improvements over existing source materials, including: predetermined and controlled heat conduction to specific parts or regions of a feature, such as improved heat conduction to certain regions, limited heat conduction such that during growth cycles The source is consumed more evenly throughout the duration of the source and has heat conduction maintained in a controlled manner, preferably uniform heat conduction. The sublimation composition (i.e., the composition of the vapor formed by the sublimation of the starting material, e.g., the flux composition) can also vary, with a composition that is more consistent or uniform throughout the cycle, or a composition that is more enhanced at the onset of growth, thereby particularly Provides better polytype stability due to stable composition.

實施例提供不同化學計量之粉末遍及形體,例如,具有不同類型之粉末起始材料、不同黏合劑之層、區帶、區域及該些者之組合及變化的分佈。不同化學計量之此預定分配提供若干優點,包括:作為源材料之昇華組合物之客製係自外部向內消耗,從而賦能自生長循環之開始至結束的組合物之較少變換。不同化學計量之此預定分配亦可由於蒸汽之一致組成而增進多型體穩定性。Embodiments provide different stoichiometric powders throughout the form, eg, layers, zones, regions, and combinations and variations of these with different types of powder starting materials, different binders. This predetermined distribution of different stoichiometries offers several advantages, including: customization of the sublimation composition as source material is consumed from the outside in, enabling less change in composition from the beginning to the end of the growth cycle. This predetermined distribution of different stoichiometries may also enhance polytype stability due to the consistent composition of the vapors.

實施例提供來源或起始材料粉末之特製化學計量、空間形體黏合劑、空間形體之添加劑、起始材料粉末之添加劑之特製化學計量、及該些者之組合及變化。例如,使用多至20%液相黏合劑及粒子意指化學計量可自1:1 Si:C,例如,自1.5:1 Si:C變換至1:1.5 Si:C,以及該些比率範圍內之所有值。涵蓋較大及較小變換。化學計量使用PDC前驅物、水、或蒸發性溶劑或非Si或非C化合物(例如,硼酸、氧化鋁、氮化鋁、硝酸鋁、硝酸鈣、磷酸鈉)來維持。化學計量係使用LDPE、炭黑、石墨粉末、碳化硼、PAN、蠟、聚乳酸、纖維素、蔗糖/糖、碳酸氫鈉、澱粉等等變換成富C的。化學計量係使用Si粉末、以富Si之SiC開始、二氧化矽、鈉鈣玻璃、硼矽酸鹽玻璃、氮化矽來變換。The examples provide tailored stoichiometry of sources or starting material powders, steric body binders, additives to steric bodies, tailored stoichiometry of additives to starting material powders, and combinations and variations of these. For example, using up to 20% liquid phase binder and particles means that the stoichiometry can be shifted from 1:1 Si:C, for example, from 1.5:1 Si:C to 1:1.5 Si:C, and within these ratios of all values. Covers both major and minor transformations. Stoichiometry is maintained using PDC precursors, water, or evaporative solvents or non-Si or non-C compounds (eg, boric acid, alumina, aluminum nitride, aluminum nitrate, calcium nitrate, sodium phosphate). Stoichiometry is converted to C-rich using LDPE, carbon black, graphite powder, boron carbide, PAN, wax, polylactic acid, cellulose, sucrose/sugar, sodium bicarbonate, starch, etc. The stoichiometry is transformed using Si powder, starting with Si-rich SiC, silicon dioxide, soda lime glass, borosilicate glass, silicon nitride.

富矽或富碳化學計量物質將在生長開始時,在蒸氣通量中分別具有較高矽或碳含量且影響生長之多型體穩定性。因此,例如,具有提供富碳氣相的源材料化學計量可增加4H多型體穩定性。在空間形體、氣體流動或兩者中具有氮摻雜可類似地增加4H多型體穩定性。同樣地,具有在2,100至2,500℃之生長溫度可增加4H多型體穩定性。Silicon-rich or carbon-rich stoichiometric species will have higher silicon or carbon content, respectively, in the vapor flux at the onset of growth and affect the polytype stability of growth. Thus, for example, having a source material stoichiometry that provides a carbon-rich gas phase can increase 4H polytype stability. Having nitrogen doping in the steric body, gas flow, or both can similarly increase 4H polytype stability. Likewise, having a growth temperature between 2,100 and 2,500°C increases 4H polytype stability.

特製粉末之化學計量的此能力可與特製富矽相之幾何位置之能力組合。以此方式,富矽相之位置可使得所耗盡SiC之「石墨化」現象可在現場反應來形成用於昇華之另外的SiC。替代地,富Si區域可在稍後生長階段期間補償汽相中減少的Si含量,從而隨後將允許遍及生長持續時間、尤其在稍後生長階段期間的更一致的矽-碳物質通量。This ability to tailor the stoichiometry of powders can be combined with the ability to tailor the geometry of the silicon-rich phase. In this way, the location of the silicon-rich phase can allow "graphitization" of depleted SiC to react in situ to form additional SiC for sublimation. Alternatively, the Si-rich region can compensate for the reduced Si content in the vapor phase during later growth stages, which will then allow for a more consistent flux of silicon-carbon species throughout the duration of growth, especially during later growth stages.

通常,用於獲得SiC之製程自液體前驅物調配物轉變成固化材料、熱解SiOC材料,其轉化為SiC材料(α、β、或兩者)。在該些製程—固化、熱解及轉化期間,各種建構塊中之一些損失,典型地為C及O。Si亦可損失,但較佳地製程及前驅物使得Si損失為最少至無損失。例如,建構成前驅物或自外部來源,例如,烘箱中建構的過量C將驅動CO超過SiO之形成,從而產生較少的Si損失。發生固化材料中之交聯度越大,在熱解及轉化期間損失的Si越低,且因此,SiC之產率越大。Typically, the process for obtaining SiC changes from a liquid precursor formulation to a cured material, pyrolyzing the SiOC material, which converts to a SiC material (alpha, beta, or both). During these processes - curing, pyrolysis and conversion, some of the various building blocks are lost, typically C and O. Si can also be lost, but preferred processes and precursors result in minimal to no Si loss. For example, excess C built up as a precursor or from an external source, eg, in an oven, will drive CO over SiO formation, resulting in less Si loss. The greater the degree of crosslinking in the cured material, the lower the Si loss during pyrolysis and conversion, and therefore, the greater the yield of SiC.

In an embodiment, the solidified SiOC is ground into granular SiOC and subsequently converted into granular SiC, which is then formed into a spatial form by means of a binder. In an embodiment, the SiOC (cured or pyrolyzed) system is formed into SiC particles. The particles can then be formed, for example, pressed into a spacer or a mass of SiC. Preferably, the size and size distribution of the SiC particles are predetermined and no further grinding is required. In embodiments, the particles can then be ground down to smaller, more uniform particles, or both, if desired. The particles can then be formed, for example, pressed into spatial bodies or masses of SiC. In these and other embodiments, when manufacturing high-purity and ultra-high-purity SiC, it is preferable to have all components of the system free of substances that would be considered impurities in subsequent uses or processes for SiC; or to have the These components are shielded, encapsulated, or otherwise mitigated to avoid introducing impurities into the process and into the SiC.

In this embodiment, one or both or neither of the precursors may be carried through distillation apparatus 151a and distillation apparatus 151b to remove any impurities from the liquid precursors. The liquid precursors are then transferred to mixing vessel 152 where they are mixed to form a precursor batch and catalyzed. In the clean room environment 157a, the precursor batches are packaged into containers 153 for placement in the furnace 154 . The furnace 154 has a sweep gas inlet 161 and a waste gas removal line 162 .

The furnace has sweep gas inlet lines 158a, 158b, 158c, respectively, and two exhaust gas removal lines 159a and 160a, 159b and 160b, 159c, and 160c, respectively.

The pyrolysis is carried out over a period of time which preferably results in complete pyrolysis of the preform. Preferably, pyrolysis occurs in an inert gas, eg, argon, and more preferably in flowing argon at or about atmospheric pressure. The gas may flow from about 1,200 cc/min to about 200 cc/min, from about 800 cc/min to about 400 cc/min, and at about 500 cc/min, and all values within these flow ranges. Preferably, initial vacuum evacuation of the processing furnace to a reduced pressure of at least less than 1E-3 Torr and repressurization with an inert gas such as argon to greater than or equal to 100 Torr is accomplished. More preferably, vacuum evacuation to a pressure below 1E-5 Torr is accomplished prior to repressurization with an inert gas. The vacuum evacuation process can be done any number of times from zero to >4 times prior to processing. Optimally, for high purity materials, the furnaces, vessels, manipulators, and other parts of the curing apparatus are clean, essentially free of and not contributing to any element or material that would be considered an impurity or contamination of the solidified material.

熱解可在維持要求溫度及環境控制之任何加熱設備中進行。因此,例如,熱解可利用以下各項來進行:高壓爐、箱式爐、管式爐、晶體生長熔爐、石墨箱式爐、電弧熔化熔爐、感應爐、窯爐、MoSi2加熱元件熔爐、碳熔爐、真空爐、氣體燃爐、電爐、直接加熱、間接加熱、流體化床、RF熔爐、窯爐、隧道式窯爐、箱式窯爐、梭動窯爐、焦炭型設備、雷射器、微波、其他電磁輻射、及可獲得用於熱解之要求溫度的該些及其他加熱設備及系統之組合及變化。Pyrolysis can be performed in any heating apparatus that maintains the required temperature and environmental controls.

在其中需要低N及O位準之實施例中,使用真空、較佳地渦輪泵來達成10E-6托並利用惰性氣體回填係更佳的。此純化製程可進行一次或多次以達成低位準。「掃掠」氣體之恆定流率可幫助在揮發性物質產生期間沖洗熔爐。In embodiments where low N and O levels are required, it is better to use a vacuum, preferably a turbo pump to achieve 10E-6 Torr and backfill with an inert gas. This purification process can be performed one or more times to achieve a low level. A constant flow rate of "sweep" gas assists in flushing the furnace during periods of volatile generation.

較佳地,在製造SiC中,陶瓷SiOC係在後續或延續熱解或轉化步驟中轉化成SiC。自SiOC之轉化步驟可為SiOC預成形件之熱解的一部分,例如與該熱解相連,或其可在時間上、位置上所及兩者上為完全獨立的步驟。取決於所要SiC之類型,可在約1,200℃至約2,550℃及約1,300℃至1,700℃,以及該些溫度範圍內之所有值下進行慣例步驟。通常,在約1,600℃至1900℃之溫度下,隨時間推移有利於β類型之形成。在高於1900℃之溫度下,隨時間推移有利於α類型之形成。較佳地,轉化發生在惰性氣體中,例如,氬中,且更佳地在或約在大氣壓力下在流動氬氣中發生。氣體可以約600 cc/min至約10 cc/min、約300 cc/min至約50 cc/min,且以約80 cc/min至約40 cc/min,以及該些流量範圍內之所有值流動。最佳地,對於高純度材料,熔爐、容器、操縱儀器、及固化設備之其他部件為清潔的,本質上不含且不貢獻將認為是SiC之雜質或污染物的任何元素或材料。Preferably, in the manufacture of SiC, the ceramic SiOC is converted to SiC in a subsequent or continuing pyrolysis or conversion step. The conversion step from SiOC may be part of, for example connected to, the pyrolysis of the SiOC preform, or it may be a completely independent step both in time and in location. Conventional steps may be performed at about 1,200°C to about 2,550°C and about 1,300°C to 1,700°C, and all values within these temperature ranges, depending on the type of SiC desired. Generally, the formation of the beta form is favored over time at temperatures of about 1,600°C to 1900°C. At temperatures above 1900°C, the formation of the alpha form is favored over time. Preferably, the conversion takes place under an inert gas, such as argon, and more preferably under flowing argon at or about atmospheric pressure. Gas can flow from about 600 cc/min to about 10 cc/min, from about 300 cc/min to about 50 cc/min, and at about 80 cc/min to about 40 cc/min, and all values within these flow ranges . Optimally, for high purity materials, the furnaces, vessels, manipulators, and other parts of the curing equipment are clean, essentially free of and not contributing to any elements or materials that would be considered impurities or contaminants of SiC.

SiOC衍生SiC之後續產率通常為約10%至50%,典型地30%至40%,雖然可獲得較高及較低範圍,以及該些百分比範圍內之所有值。The subsequent yield of SiOC derived SiC is typically about 10% to 50%, typically 30% to 40%, although higher and lower ranges are available, and all values within these percentage ranges.

最佳地,當製造高純度SiC時,與製造、固化、熱解及轉化材料相關聯的活動係在清潔室條件中、清潔室條件下,例如,在至少ISO 5、至少ISO 4、至少ISO 3、至少ISO 2、及至少ISO 1之ISO 14644-1清潔室標準下進行。在實施例中,材料操縱步驟係在至少ISO 5之清潔室中進行,而次清潔區域(ISO >5)係用於熱解及轉化步驟。Optimally, when manufacturing high purity SiC, the activities associated with manufacturing, curing, pyrolyzing and converting the material are in clean room conditions, under clean room conditions, e.g., at least ISO 5, at least ISO 4, at least ISO 3. At least ISO 2, and at least ISO 1 ISO 14644-1 clean room standard. In an embodiment, the material handling steps are performed in a clean room of at least ISO 5, while a less clean area (ISO > 5) is used for the pyrolysis and conversion steps.

SiC或SiOC及超純SiC或SiOC之空間形體可為任何預定空間形體,包括例如球體、圓片、團塊、環、透鏡、圓盤、面板、圓錐體、截錐形體、正方形體、矩形體、桁架、有角體(angle)、通道、中空密封室、中空球體、塊體、片材、塗層、膜、外皮、微粒、束、棒、有角體、平板、管柱、纖維、切斷纖維、管、杯、管道、及該些及其他更複雜形狀之組合及各種形體,皆可為工程化及建築學的。The spatial shape of SiC or SiOC and ultrapure SiC or SiOC can be any predetermined spatial shape, including, for example, spheres, disks, agglomerates, rings, lenses, disks, panels, cones, frustums, squares, rectangles , Truss, Angle, Channel, Hollow Sealed Chamber, Hollow Sphere, Block, Sheet, Coating, Membrane, Skin, Particle, Bundle, Rod, Angle, Flat Plate, Column, Fiber, Cut Broken fibers, tubes, cups, pipes, and combinations of these and other more complex shapes and shapes can be engineered and architectural.

在製造空間形體中,添加至SiC之黏合劑的量可與SiC粒子之輕塗層相差達形成類似漿料之糊狀物的充分量。因此,取決於成形設備要求、空間形體及黏合劑自身之強度要求,將約0.1%至約65%、約0.1%至約45%、約0.5%至約40%、約20%至約40%、約1%至約15%、及約2%至約7%、約1%及更多、約2%及更多、及約3%及更多的黏合劑添加至SiC以形成漿料或摻合物,以及添加該些百分比範圍內之所有量。取決於在固化期間的黏合劑損失之量,此可產生空間形體,在該空間形體中具有約0.05%至約25%、約0.75%至約12%、1%至約5%、約1%及更多、約2%及更多、約4%及更多、約6%及更多的固化黏合劑,以及該些百分比範圍內之所有量。In the fabrication of spatial shapes, the amount of binder added to SiC can differ from a light coating of SiC particles by a sufficient amount to form a slurry-like paste. Therefore, about 0.1% to about 65%, about 0.1% to about 45%, about 0.5% to about 40%, about 20% to about 40% , about 1% to about 15%, and about 2% to about 7%, about 1% and more, about 2% and more, and about 3% and more binder added to SiC to form a slurry or Blends, and all amounts within these percentage ranges are added. Depending on the amount of binder loss during curing, this can result in a space feature in which there is about 0.05% to about 25%, about 0.75% to about 12%, 1% to about 5%, about 1% and more, about 2% and more, about 4% and more, about 6% and more of cured adhesive, and all amounts within those percentage ranges.

與黏合劑混合以形成空間形體之SiC顆粒之大小可為約0.1 μm(微米)至約100 μm、約0.5 μm至約50 μm、約 0.3 μm至約20 μm、約0.3 μm至約10 μm、及較大及較小大小,以及不同大小之組合,以及該些大小範圍內之所有值。因此,顆粒可具有以下初級粒子D 50大小:約0.1 μm至約20.0 μm、約0.5 μm至約10.0 μm、約 0.5 μm至約2.0 μm、約0.5 μm至約1.0 μm、約 1 μm至約5 μm、約1 μm、約2 μm、約3 μm、及較大及較小D 50大小,以及該些大小範圍內之所有值。 The size of the SiC particles mixed with the binder to form the spatial shape can be from about 0.1 μm (micrometer) to about 100 μm, from about 0.5 μm to about 50 μm, from about 0.3 μm to about 20 μm, from about 0.3 μm to about 10 μm, and larger and smaller sizes, and combinations of different sizes, and all values within those size ranges. Thus, the particles may have the following primary particle D50 sizes: about 0.1 μm to about 20.0 μm, about 0.5 μm to about 10.0 μm, about 0.5 μm to about 2.0 μm, about 0.5 μm to about 1.0 μm, about 1 μm to about 5 μm, about 1 μm, about 2 μm, about 3 μm, and larger and smaller D 50 sizes, and all values within those size ranges.

黏合劑可為用於在處理、固化及空間形體之稍後使用期間保持預定形體中之SiC的任何黏合劑。黏合劑之實施例可較佳為無氧的。黏合劑之實施例可較佳地由僅具有碳及氫之材料製成。黏合劑之實施例可由具有氧之材料製成。黏合劑之實施例可為用於燒結SiC之任何燒結助劑。黏合劑之實施例可為熔融二氧化矽。黏合劑之實施例可為多晶碳氧矽前驅物材料,包括本說明書中闡述的所有液體前驅物。該些及其他材料之組合及變化亦可用作黏合劑。The binder may be any binder used to retain the SiC in the preform during handling, curing and later use of the spatial form. Embodiments of the binder may preferably be oxygen-free. Embodiments of the adhesive may preferably be made of materials having only carbon and hydrogen. Embodiments of the adhesive may be made from materials that have oxygen. An example of a binder can be any sintering aid used for sintering SiC. An example of a binder may be fused silica. Examples of binders may be polycrystalline silicon oxycarbide precursor materials, including all liquid precursors described in this specification. Combinations and variations of these and other materials can also be used as adhesives.

黏合劑可在用於固化多晶碳氧矽前驅物之條件下,或在需要將黏合劑轉變成足夠硬(例如,堅韌)材料以維持空間形體之形狀所需的條件下固化至所需程度。因此,視情況,固化、硬化、成形、或定型應基於黏合劑之特性來進行。應作未來考慮以防止黏合劑之固化或硬化或定型引入雜質或其他非所欲物質至空間形體中。The binder can be cured to the desired extent under the conditions used to cure the polycrystalline silicon oxycarbide precursor, or under the conditions needed to convert the binder into a sufficiently hard (eg, tough) material to maintain the shape of the spatial form . Therefore, curing, hardening, shaping, or setting, as the case may be, should be performed based on the properties of the adhesive. Future considerations should be taken to prevent the curing or hardening or setting of the adhesive from introducing impurities or other undesirable substances into the spatial form.

對於用於諸如生長胚晶及用於製造晶圓之應用的純及超純SiC材料而言,黏合劑材料較佳不含認為是污染物的所有材料。因此,在實施例中,黏合劑材料為至少5個九、至少6個九、至少7個九、及至少8個九純的,例如,為不含認為是污染物之材料。For pure and ultrapure SiC materials for applications such as growing embryonic crystals and for manufacturing wafers, the binder material is preferably free of all materials considered to be contaminants. Thus, in embodiments, the binder material is at least 5 nines, at least 6 nines, at least 7 nines, and at least 8 nines pure, eg, free of materials considered contaminants.

較佳地,黏合劑之使用不向SiC或SiOC添加污染物及可偵測量之污染物。在實施例中,黏合劑亦維持Si:C之適當化學計量以在處理之後維持接近矽原子對碳原子之1:1比率。在實施例中,黏合劑具有Si:C之預定比率,其為富碳、貧碳、或化學計量的以提供具有預定SiC比率之空間形體。Preferably, the use of the binder does not add contaminants and detectable amounts of contaminants to the SiC or SiOC. In an embodiment, the binder also maintains a proper stoichiometry of Si:C to maintain a near 1:1 ratio of silicon atoms to carbon atoms after processing. In an embodiment, the binder has a predetermined ratio of Si:C that is carbon-rich, carbon-poor, or stoichiometric to provide a steric form with a predetermined SiC ratio.

對於純及超純SiC應用及材料而言,黏合劑可較佳地為化妝等級、電子學等級、及外科等級材料。For pure and ultrapure SiC applications and materials, the binder may preferably be cosmetic grade, electronics grade, and surgical grade materials.

黏合劑之實施例將包括催化及未催化的前驅物調配物,如美國專利第9,499,677號、第9,481,781號及美國專利公開案第2014/0274658號、第2014/0323364號、第2015/0175750號、第2016/0207782號、第2016/0280607號、第2017/0050337號中所揭示及教示,其中每一者之全部揭示內容係以引用方式併入本文中。固化該些黏合劑之方法係揭示及教示於該些專利及公開的申請案中,其中每一者之全部揭示內容係以引用方式併入本文中。Examples of binders would include catalyzed and uncatalyzed precursor formulations such as U.S. Patent Nos. 9,499,677, 9,481,781 and U.S. Patent Publication Nos. 2014/0274658, 2014/0323364, 2015/0175750, Disclosed and taught in Nos. 2016/0207782, 2016/0280607, 2017/0050337, the entire disclosure of each of which is incorporated herein by reference. Methods of curing the adhesives are disclosed and taught in these patents and published applications, the entire disclosure of each of which is incorporated herein by reference.

在較佳實施例中,SiC空間形體係使用聚合物衍生、及較佳地多晶碳氧矽聚合物衍生SiC (例如,如美國公開案第2016/0207782號中所教示及揭示,其係以引用方式併入本文中)、及多晶碳氧矽黏合劑來製成。在實施例中,SiC係來自習知來源。此實施例為次較佳的,如咸信慣例SiC具有不同的結構,例如,形態學及表面性質,從而在諸如氣相沉積之應用中產生比聚合物衍生SiC差的效能。在實施例中,空間形體為聚合物衍生SiC及習知SiC之混合物。In a preferred embodiment, the SiC space-shape system uses polymer-derived, and preferably polycrystalline silicon oxycarbide polymer-derived SiC (for example, as taught and disclosed in U.S. Publication No. 2016/0207782, which is based on Incorporated herein by reference), and polycrystalline silicon oxycarbide adhesive to make. In an embodiment, the SiC system is from a known source. This embodiment is less preferred, as conventional SiC is believed to have different structures, eg, morphology and surface properties, resulting in poorer performance than polymer derived SiC in applications such as vapor deposition. In an embodiment, the spatial form is a mixture of polymer derived SiC and conventional SiC.

在實施例中,黏合劑係用於為小片、珠粒或空間形體提供傳導性。因此,黏合劑可為碳、矽,或可現場分解成導電物質,諸如碳—實例包括多醣、PE、烴油及蠟等等或多晶碳氧矽調配物,其具有大的碳過量且因此遠不能達成Si:C化學計量且替代地現場形成C-SiC複合物,或可具有添加至其的碳及矽。以此方式,空間形體,例如,圓盤、圓片、團塊、珠粒、小片、彈丸、等等具有在20℃下低於10,000 ohm-cm、在20℃下低於8,000 ohm-cm、在20℃下低於5,000 ohm-cm、及在20℃下低於2,000 ohm-cm,以及該些電阻率範圍內之所有值之電阻率。In an embodiment, a binder is used to provide conductivity to the platelets, beads or spatial features. Thus, the binder can be carbon, silicon, or decomposable in situ into conductive species such as carbon - examples include polysaccharides, PE, hydrocarbon oils and waxes, etc. Si:C stoichiometry is far from being achieved and instead a C-SiC composite is formed in situ, or may have carbon and silicon added to it. In this way, spatial features such as discs, discs, agglomerates, beads, flakes, pellets, etc. have an Resistivity below 5,000 ohm-cm at 20°C, and below 2,000 ohm-cm at 20°C, and all values within these resistivity ranges.

通常,在實施例中,黏合劑材料在700℃下完全揮發、在600℃下完全揮發、及在500℃下完全揮發,以及在該些溫度範圍內之所有值下完全揮發。當使用不同類型之PDC作為黏合劑材料時,揮發範圍可變化,且因此用於黏合劑之揮發的溫度範圍可在約900℃至約300℃範圍變化,以及該些溫度範圍內之所有值。亦較佳的是,黏合劑之揮發組分不沉積於,或以其他方式形成於、結垢或污染設備之內部部件,該設備係用於自SiC製造結構,例如,氣相沉積裝置。Typically, in embodiments, the binder material is fully volatile at 700°C, fully volatile at 600°C, and fully volatile at 500°C, and at all values within these temperature ranges. When different types of PDC are used as the binder material, the volatilization range can vary, and thus the temperature range for volatilization of the binder can vary from about 900°C to about 300°C, and all values within these temperature ranges. It is also preferred that volatile components of the adhesive do not deposit on, or otherwise form on, foul or contaminate internal components of equipment used to fabricate structures from SiC, eg, vapor deposition devices.

與超純SiC一起使用以形成空間形體,例如,小片、圓盤、圓片、彈丸、團塊、珠粒的在20℃下具有低於8,000 ohm-cm之電阻率及至少約5個九之純度(空間形體之純度)的黏合劑材料之較佳實施例為矽金屬、碳粉末、烴蠟、純聚乙烯、及主要含有矽及碳及氫之可蒸餾化合物及聚合物衍生陶瓷前驅物及該些者之組合及變化。Use with ultrapure SiC to form spatial features such as pellets, disks, discs, pellets, pellets, beads having a resistivity of less than 8,000 ohm-cm and at least about 5 nines at 20°C Preferred examples of binder materials for purity (stereomorphic purity) are silicon metals, carbon powders, hydrocarbon waxes, pure polyethylene, and distillable compounds and polymer-derived ceramic precursors mainly containing silicon and carbon and hydrogen and combinations and variations thereof.

用於形成空間形體之設備及製程將包括例如冷壓機、冷等靜壓機、熱壓機、熱等靜壓機、擠壓機、模鑄、及模製製程及該些者之組合及變化。Equipment and processes for forming spatial shapes will include, for example, cold presses, cold isostatic presses, hot presses, hot isostatic presses, extruders, die casting, and molding processes and combinations thereof and Variety.

在利用直接通量、回流、分餾或分昇華的實施例及其中預定形體將要在生長循環之大部分及較佳地全部期間保持其結構完整性的其他實施例中,黏合劑必須使得其不昇華或以其他方式損失維持空間形體之結構完整性之能力。該些類型之黏合劑之實例將包括PDC前驅物作為黏合劑。用於維持空間形體之結構完整性例如以便用作回流結構的較佳實施例將為10重量%-15重量%純的PDC前驅物材料。In embodiments utilizing direct flux, reflux, fractional distillation, or subsublimation, and other embodiments where the predetermined shape is to retain its structural integrity during most, and preferably all, of the growth cycle, the binder must be such that it does not sublime Or otherwise lose the ability to maintain the structural integrity of the spatial form. Examples of these types of binders would include PDC precursors as binders. A preferred embodiment for maintaining the structural integrity of the spatial form, eg, for use as a reflow structure, would be 10 wt% - 15 wt% pure PDC precursor material.

以本質上具有製造SiC所需的例如Si及C之所有建構塊的例如前驅物批料之液體材料開始的能力在控制雜質、污染,及在製造高純度SiOC中提供顯著優勢,該高純度SiOC又可轉化成高純度SiC或可直接在單一組合製程或步驟中製成。亦在理論上,部分地基於氣相沉積設備及生長胚晶中的本發明之聚合物衍生SiC之效能,聚合物衍生SiC顯著地不同於非聚合物衍生SiC。因此,胚晶生長及純度、晶圓產率及裝置產率中之協同益處進一步由本發明之個別益處產生,該等益處為體密度、粒子大小、SiC之相(β相對α)、化學計量、氧含量(極低至無,及缺少氧化物層)、高及超高純度。The ability to start with a liquid material, such as a precursor batch, that essentially has all the building blocks needed to make SiC, such as Si and C, provides significant advantages in controlling impurities, contamination, and in the production of high-purity SiOC that It can in turn be converted to high-purity SiC or can be made directly in a single combined process or step. It is also theoretical, based in part on the performance of the polymer-derived SiC of the present invention in vapor deposition equipment and growing embryos, that polymer-derived SiC differs significantly from non-polymer-derived SiC. Thus, synergistic benefits in embryonic growth and purity, wafer yield, and device yield result further from the individual benefits of the present invention, which are bulk density, particle size, phase of SiC (beta vs. alpha), stoichiometry, Oxygen content (very low to none, and lack of oxide layer), high and ultra-high purity.

因此,本發明之實施例提供SiOC及SiOC空間形體之使用,該等空間形體為至少約99.9% (3個九)、至少約99.99% (4個九)、至少約99.999% (5個九)、及至少約99.9999% (6個九)及至少約99.99999% (7個九)或更大純度,以及該些純度範圍內之所有值。類似地,本發明之實施例提供SiC及SiC空間形體之使用,該等空間形體為至少約99.9%(3個九)、至少約99.99% (4個九)、至少約99.999% (5個九)、及至少約99.9999% (6個九)及至少約99.99999% (7個九)或更大純度,以及該些純度範圍內之所有值。該些純度值係視情況基於SiOC或SiC相對存在或含在SiOC或SiC產品之給定樣本內的所有材料之量。如本文所使用,SiOC或SiC產品將係指粉末SiOC或SiC,以及,該些材料之空間形體。具有適當黏合劑選擇的SiC及SiOC之空間形體之實施例具有相同純度位準。Accordingly, embodiments of the present invention provide for the use of SiOC and SiOC spatial shapes that are at least about 99.9% (3 nines), at least about 99.99% (4 nines), at least about 99.999% (5 nines) , and at least about 99.9999% (6 nines) and at least about 99.99999% (7 nines) or greater purity, and all values within such purity ranges. Similarly, embodiments of the present invention provide for the use of SiC and SiC spatial features that are at least about 99.9% (3 nines), at least about 99.99% (4 nines), at least about 99.999% (5 nines) ), and at least about 99.9999% (6 nines) and at least about 99.99999% (7 nines) or greater purity, and all values within such purity ranges. These purity values are based on the SiOC or SiC relative to the amount of all materials present or contained within a given sample of SiOC or SiC product, as the case may be. As used herein, SiOC or SiC products shall refer to powdered SiOC or SiC, and the spatial forms of these materials. Embodiments of spatial features of SiC and SiOC with proper binder selection have the same purity level.

亦注意,若污染物係以不會不利地影響SiC及SiOC在其所欲製造製程或最終用途中之使用;及不會不利地影響由SiC及SiOC起始材料製成的最終產品的方式揮發(或以其他方式移除),則空間形體之較低純度位準可為可接受的。因此,例如,其中SiC為7個九純的SiC之4個九純圓盤及降低該圓盤之總體純度的黏合劑係在胚晶成形氣相沉積製程中的達到700℃之圓盤可為可接受的之前加以移除。另外,過重(較高AMU)之雜質可俘獲在圓片內,且因此,得以緩和。Note also that if the contaminants are volatilized in a manner that does not adversely affect the use of SiC and SiOC in their intended manufacturing process or end use; and does not adversely affect the final product made from the SiC and SiOC starting materials (or otherwise removed), a lower purity level of the spatial form may be acceptable. Thus, for example, 4 nine-pure discs of SiC in which SiC is 7 nine-pure and a binder that reduces the overall purity of the pucks can be used for disks up to 700°C in an embryonic crystal forming vapor deposition process. Removed before acceptable. Additionally, impurities that are too heavy (higher AMU) can be trapped within the wafer and, therefore, moderated.

在本發明之實施例中,高純度SiC空間形體具有低、極低及低於偵測極限的量之引起顯著問題或在物件之稍後處理及製造中視為雜質的材料,該等物件例如,胚晶、晶圓、電子部件、光學部件及其他基於SiC的中間物及最終產品。In embodiments of the present invention, the high purity SiC spacers have low, very low, and below detection limit amounts of materials that cause significant problems or are considered impurities in later processing and fabrication of objects such as, Embryos, wafers, electronic components, optical components and other SiC-based intermediates and final products.

因此,聚合物衍生高純度SiC、及尤其多晶碳氧矽衍生高純度SiOC,以及SiOC所轉化成的高純度SiC具有至少約99.9%、至少約99.99%、至少約99.999%、及至少約99.9999%及至少約99.99999%或更大之純度。進一步,應注意,本發明之實施例包括具有任何純度位準之聚合物衍生SiC及SiOC,包括較低位準之純度,諸如99.0%、95%、90%及更低。咸信該些較低,例如,非高純度實施例具有及將得到實質使用及應用。類似地,咸信高純度SiC之實施例將得到應用、使用,且為應用提供新的及令人驚訝的益處,該等益處在本發明之前係限於Si或不同於SiC之材料。具有適當黏合劑選擇的SiC之空間形體之實施例具有相同純度位準。Thus, polymer-derived high-purity SiC, and particularly polycrystalline silicon oxycarbide-derived high-purity SiOC, and SiOC converted to high-purity SiC have at least about 99.9%, at least about 99.99%, at least about 99.999%, and at least about 99.9999% % and at least about 99.99999% or greater in purity. Further, it should be noted that embodiments of the present invention include polymer derived SiC and SiOC having any level of purity, including lower levels of purity, such as 99.0%, 95%, 90% and lower. It is believed that these lower, eg, non-high purity embodiments have and will find substantial use and application. Similarly, it is believed that embodiments of high purity SiC will find application, use, and provide new and surprising benefits for applications that prior to the present invention were limited to Si or materials other than SiC. Embodiments of SiC spatial features with proper binder selection have the same purity level.

本發明之實施例包括高純度SiC在製造用於電子學及半導體應用中之應用的晶圓中的用途。在產生胚晶及晶圓用於稍後使用的氣相沉積設備及製程兩者中,需要高純度SiC。詳言之,如表1所闡述,高純度SiC之實施例可較佳地具有低位準的表1中之一種、多於一種、及所有要素,其在某些氣相沉積設備、電子學應用、及半導體應用中被認為是雜質。因此,SiC粒子及空間形體之實施例可不含雜質,實質上不含雜質,且含有一些但具有不超過表1陳述的量及量之組合。Embodiments of the present invention include the use of high purity SiC in the manufacture of wafers for applications in electronics and semiconductor applications. High purity SiC is required both in the vapor deposition equipment and in the process to create embryos and wafers for later use.

在實施例,Pr亦可在一些應用中認為是雜質,且若如此認為,則表1之極限及量可適用於Pr。In an example, Pr may also be considered an impurity in some applications, and if so considered, the limits and amounts in Table 1 may apply to Pr.

除非另外指定,否則如本文所使用,當提及純度位準、高純度、純度%、雜質%、及類似的此種術語時,在材料之計算或表徵中不包括、提及、認為、或使用過量碳,亦即,超過化學計量的SiC。在一些應用中,過量碳可對應用或產品具有小的效應至不具有效應,且因此,將不認為是雜質。在其他應用中,過量的碳可為有益的,例如,碳可充當燒結助劑;過量碳可用於解決且補償氣相沉積設備及製程中之不規則性,且可用於控制或實現氣相沉積製程。Unless otherwise specified, as used herein, when referring to purity level, high purity, % purity, % impurity, and similar such terms, calculations or characterizations of materials do not include, refer to, assume, or Excess carbon is used, that is, SiC over stoichiometric. In some applications, excess carbon may have little to no effect on the application or product, and therefore, would not be considered an impurity. In other applications, excess carbon can be beneficial, for example, carbon can act as a sintering aid; excess carbon can be used to address and compensate for irregularities in vapor deposition equipment and processes, and can be used to control or enable vapor deposition Process.

在其中氮係視為污染物之應用中,多晶碳氧矽衍生SiC及SiOC之實施例可具有小於約10,000 ppm、小於1000 ppm、小於約100 ppm、小於約10 ppm、小於約1 ppm及小於約0.1 ppm及更低的氮,及約1000 ppm至約0.01 ppm的氮、約100 ppm至約0.001 ppm的氮。SiC之空間形體之實施例具有相同純度位準。Embodiments of polycrystalline silicon oxycarbide derived SiC and SiOC may have less than about 10,000 ppm, less than 1000 ppm, less than about 100 ppm, less than about 10 ppm, less than about 1 ppm and Less than about 0.1 ppm nitrogen and lower, and about 1000 ppm to about 0.01 ppm nitrogen, about 100 ppm to about 0.001 ppm nitrogen.

在多晶碳氧矽衍生SiC之實施例中,其本質上不含及不含呈任何形式的氧之存在,該形式為結合至Si或C或作為氧化物層。因此,多晶碳氧矽衍生SiC及SiC之空間形體的實施例可具有小於約10,000 ppm、小於1000 ppm、小於約100 ppm、小於約10 ppm、小於約1 ppm及小於約0.1 ppm及更低的氧,及約1000 ppm至約0.01 ppm的氧、約100 ppm至約0.001 ppm的氧。多晶碳氧矽衍生SiC具有在標準溫度及壓力下暴露於空氣時抵抗且不形成氧化物層之能力。在環境條件下儲存時不存在氧化物層,亦即,無氧化物層之SiC在稍後製造製程中提供優點,其中氧化物層可視為雜質,或另外視為對製造製程之有害物。SiC之空間形體之實施例具有相同純度位準。In the embodiment of polycrystalline silicon oxycarbide derived SiC, it is essentially free and free of the presence of oxygen in any form, either bound to Si or C or as an oxide layer. Thus, embodiments of polycrystalline silicon oxycarbide derived SiC and SiC steric features can have less than about 10,000 ppm, less than 1000 ppm, less than about 100 ppm, less than about 10 ppm, less than about 1 ppm, and less than about 0.1 ppm and lower oxygen, and oxygen from about 1000 ppm to about 0.01 ppm, and oxygen from about 100 ppm to about 0.001 ppm. Polycrystalline silicon oxycarbide derived SiC has the ability to resist and not form an oxide layer when exposed to air at standard temperature and pressure. The absence of an oxide layer when stored under ambient conditions, ie SiC without an oxide layer provides advantages later in the manufacturing process where the oxide layer may be considered an impurity, or otherwise detrimental to the manufacturing process. Embodiments of spatial features of SiC have the same purity level.

本發明之多晶碳氧矽SiC及SiC胚晶、晶圓及由多晶碳氧矽衍生SiC製成的其他結構之實施例展現多形性,且通常展現稱為多型性之一維多形性。因此,多晶碳氧矽衍生SiC可在許多、理論上無限的不同多型體中存在。如本文所使用,除非另外明確地提供,否則術語多型性、多型體及類似的此種術語應給定其最廣可能的含義,且將包括各種不同的碳化矽四面體(SiC 4)藉由得以配置的框架、結構、或排列。通常,該些多型體分成兩個種類-阿爾法(α)及貝他β)。 Embodiments of polycrystalline silicon oxycarbide SiC and SiC embryos, wafers, and other structures made from polycrystalline silicon oxycarbide derived SiC of the present invention exhibit polymorphism, and often exhibit a multi-dimensional nature known as polymorphism. Formality. Thus, polycrystalline silicon oxycarbide derived SiC can exist in many, theoretically infinite, different polytypes. As used herein, unless expressly provided otherwise, the terms polymorphism, polytype and similar such terms shall be given their broadest possible meaning and shall include the various silicon carbide tetrahedra (SiC 4 ) By a frame, structure, or arrangement to be configured. Generally, these polytypes are divided into two classes - alpha (α) and beta (β).

多晶碳氧矽衍生SiC之α種類之實施例典型地含有六邊形(H)、菱面體(R)、三角形(T)結構且可含有該些者之組合。β種類典型地含有立方體(C)或閃鋅礦結構。因此,例如,多晶碳氧矽衍生碳化矽之多型體將包括:3C-SiC (β – SiC或β 3C-SiC),其具有ABCABC...之疊積序列;2H-SiC,其具有ABAB...之疊積序列;4H-SiC,其具有ABCBABCB...之疊積序列;及6H-SiC(α碳化矽之一般形式,α 6H-SiC),其具有ABCACBABCACB...之疊積序列。由α碳化矽形成之其他者的實例將包括8H、10H、16H、18H、19H、15R、21R、24H、33R、39R、27R、48H、及51R。Embodiments of the alpha species of polycrystalline silicon oxycarbide derived SiC typically contain hexagonal (H), rhombohedral (R), triangular (T) structures and may contain combinations of these. Beta species typically contain cubic (C) or sphalerite structures. Thus, for example, polytypes of polycrystalline silicon oxycarbide derived silicon carbide would include: 3C-SiC (β-SiC or β 3C-SiC), which has the stacking sequence ABCABC...; 2H-SiC, which has The stacking sequence of ABAB...; 4H-SiC, which has the stacking sequence of ABCBABCB...; and 6H-SiC (the general form of alpha silicon carbide, α6H-SiC), which has the stacking sequence of ABCACBABCACB... Product sequence. Examples of others formed from alpha silicon carbide would include 8H, 10H, 16H, 18H, 19H, 15R, 21R, 24H, 33R, 39R, 27R, 48H, and 51R.

多晶碳氧矽衍生SiC之實施例可為多晶或單一(單)結晶的。通常,在多晶材料中,在材料之兩個顆粒或微晶之間存在顆粒邊界作為界面。該些顆粒邊界可在具有不同定向的相同多型體之間、或在具有相同或不同定向之不同多型體之間、及該些者之組合及變化。單結晶結構由單一多型體製成且基本上不具有顆粒邊界。Embodiments of polycrystalline silicon oxycarbide derived SiC may be polycrystalline or single (single) crystalline. Typically, in polycrystalline materials, grain boundaries exist as interfaces between two grains or crystallites of the material. The grain boundaries can be between the same polytype with different orientations, or between different polytypes with the same or different orientations, and combinations and variations of these. A single crystalline structure is made of a single polytype and has essentially no grain boundaries.

大體上,用於自SiC胚晶製造電子部件之製程涉及將SiC單結晶胚晶切割成薄晶圓。晶圓具有胚晶之直徑且典型地具有約100 μm至約500 μm之厚度。隨後將晶圓在一側或兩側上拋光。隨後將拋光晶圓用作用於所製造微電子半導體裝置之基板。因此,晶圓用作用於微電子裝置之基板,該等微電子裝置建構在晶圓中,建構在晶圓上或兩者兼有。該些微電子裝置之製造包括微製造處理步驟,諸如,各種材料之磊晶生長、摻雜或離子植入、蝕刻、沉積,及光刻圖案化,僅舉幾例。一旦自晶圓製造,該晶圓及因此個別微電路在稱為切割的製程中分離成個別半導體裝置。該些裝置隨後用於製造,例如,併入各種較大半導體及電子裝置中。In general, the process for fabricating electronic components from SiC embryos involves dicing SiC single crystal embryos into thin wafers. The wafer has the diameter of an embryonic crystal and typically has a thickness of about 100 μm to about 500 μm. The wafer is then polished on one or both sides. The polished wafers are then used as substrates for the fabricated microelectronic semiconductor devices. Thus, wafers are used as substrates for microelectronic devices built in the wafer, on the wafer, or both. The fabrication of these microelectronic devices includes microfabrication processing steps such as epitaxial growth of various materials, doping or ion implantation, etching, deposition, and photolithographic patterning, to name a few. Once fabricated from a wafer, the wafer and thus the individual microcircuits are separated into individual semiconductor devices in a process called dicing.

For example, the stiffness is reduced to 10 MPa or less. In embodiments of these lower strength structures, hydrocarbon waxes, for example, may be used and provide significantly less stiffness than, for example, vitrified adhesives.

大體上,在一些實施例中,該些SiC空間形體弱於其下伏SiC材料,該下伏SiC材料構成其結構,且具有以下報告值:約410 GPa之彈性模數、約2,800 Kg/mm 2之硬度及約3,900 MPa之壓縮強度,該些者之組合及變化,以及該些性質範圍內之所有值。藉由氦比重測定法量測的SiC之實際密度為約3.0至3.5 g/cc、或約3.1至3.4 g/cc、或約3.2至3.3 g/cc,及該些者之組合及變化,以及該些性質範圍內之所有值。例如團塊、彈丸等等的SiC之空間形體之實施例的表觀密度或比重可顯著更低。 In general, in some embodiments, the SiC spacers are weaker than the underlying SiC material that makes up their structure and have the following reported values: elastic modulus of about 410 GPa, about 2,800 Kg/mm 2 and compressive strength of about 3,900 MPa, combinations and variations of these, and all values within the range of these properties. the actual density of SiC as measured by helium pycnometric method is about 3.0 to 3.5 g/cc, or about 3.1 to 3.4 g/cc, or about 3.2 to 3.3 g/cc, and combinations and variations thereof, and All values within the range of these properties. Embodiments of spatial features of SiC such as pellets, pellets, etc. may have significantly lower apparent densities or specific gravity.

在實施例中,SiC之空間形體之質量較佳地及典型地具有比其SiC實際密度低的表觀密度,例如,SiC顆粒之實際密度應為約3.1 g/cc至3.3 g/cc。空間形體(例如,圓片、團塊、立方體、球、珠粒、圓盤或板)之表觀密度可小於約3 g/cc、小於約2 g/cc、小於約1 g/cc及更低,且可為約0.5 g/cc至約1.8 g/cc、約0.4 g/cc至約2 g/cc。SiC之粒子的體密度可小於約3.0 g/cc、小於約2.0 g/cc、小於約1 g/cc、及約0.1 g/cc至約2 g/cc、0.5 g/cc至約1.5 g/cc。亦涵蓋較大及較低表現密度及體密度。此外,聚合物衍生SiC之空間形體的特定,亦即,預定及精確表現密度可提供來匹配,且較佳地增進且更佳地最佳化稍後的製造製程。例如,在PVT晶圓製造中,SiC顆粒之空間形體可具有經特定設計及特製來匹配特定PVT設備之表觀密度。以此方式,設施中的每一PVT設備可具有客製進料儲備,其藉由使用具有預定及精確特性的進料儲備(例如,SiC之空間形體)賦能每一設備之效能得以最佳化,該等特性諸如形狀、體積、重量、填積因子、體密度、敲緊密度、及表觀密度。In an embodiment, the quality of the SiC spatial features preferably and typically has an apparent density lower than the actual density of SiC, eg, the actual density of SiC particles should be about 3.1 g/cc to 3.3 g/cc. Apparent densities of spatial forms (e.g., discs, pellets, cubes, spheres, beads, discs, or plates) can be less than about 3 g/cc, less than about 2 g/cc, less than about 1 g/cc, and more Low, and can be from about 0.5 g/cc to about 1.8 g/cc, from about 0.4 g/cc to about 2 g/cc. Particles of SiC can have a bulk density of less than about 3.0 g/cc, less than about 2.0 g/cc, less than about 1 g/cc, and about 0.1 g/cc to about 2 g/cc, 0.5 g/cc to about 1.5 g/cc cc. Greater and lower apparent densities and volume densities are also covered. Furthermore, the specificity of the spatial morphology of polymer derived SiC, ie a predetermined and precise representation density can be provided to match and preferably enhance and better optimize the later manufacturing process. For example, in PVT wafer fabrication, the spatial profile of SiC particles can have a specifically designed and tailored apparent density to match a particular PVT device. In this way, each PVT device in a facility can have a custom feedstock that enables the performance of each device to be optimized by using a feedstock with predetermined and precise characteristics (e.g., SiC's spatial profile) Chemical properties such as shape, volume, weight, packing factor, bulk density, tapped density, and apparent density.

在實施例中,SiC之空間形體可具有建構在形體中的多孔性,其較佳地藉由黏合劑或連同黏合劑一起提供。此多孔性係較佳地為開孔、或實質上開孔多孔性。以此方式,空間形體典型地提供比粒狀SiC實質上大的可用表面面積,因為形體之結構包括將不會存在於SiC粒子之疏鬆堆中的孔隙表面,例如,顆粒彼此抵靠填積的情況。因此,例如,若SiC之圓盤係用於氣相沉積製程以製成SiC胚晶(用於後續轉化成SiC晶圓),則相較可典型地自在此種製程中使用粒狀SiC所獲得者而言,該些SiC圓盤將提供實質上更大的表面面積以自其產生SiC蒸汽,及用於SiC蒸汽之移動的實質上更大路徑。理論上,增加的表面面積及增加的路徑提供增加SiC胚晶之生長速率、SiC胚晶(及因此後續晶圓)之品質及此二者的能力。SiC圓盤,例如,SiC之空間形體可比粒狀SiC材料更易於操縱、量測、及使用。In an embodiment, the spatial features of SiC may have porosity built into the features, preferably provided by or in conjunction with a binder. The porosity is preferably open-cell, or substantially open-cell porosity. In this way, spatial features typically provide substantially greater usable surface area than granular SiC because the structure of the features includes pore surfaces that would not exist in a loose pack of SiC particles, e.g., where the particles pack against each other. Condition. Thus, for example, if a disk of SiC is used in a vapor deposition process to make SiC embryos (for subsequent conversion into SiC wafers), then compared to that typically obtained from the use of granular SiC in such a process Alternatively, the SiC discs will provide a substantially larger surface area from which to generate SiC vapor, and a substantially larger path for movement of the SiC vapor. In theory, the increased surface area and increased pathways provide the ability to increase the growth rate of the SiC embryo, the quality of the SiC embryo (and thus the subsequent wafer), and both. SiC discs, for example, SiC spatial features can be easier to manipulate, measure, and use than granular SiC material.

在實施例中,空間形體可由SiC之顆粒製成,該等顆粒藉由將自熱解爐移除的SiC之易碎質塊***開來獲得。就此而言,可控制用於製造空間形體的顆粒大小。在一些實施例中,此舉亦提供對黏合劑添加及混合製程的較大控制。In an embodiment, the spatial body can be made of particles of SiC obtained by breaking apart a friable mass of SiC removed from a pyrolysis furnace. In this regard, the size of the particles used to create the spatial features can be controlled. In some embodiments, this also provides greater control over the binder addition and mixing process.

對實施例而言,SiC之易碎質塊較佳地及典型地具有比其實際密度顯著更低的表觀密度,例如,實際密度應為約3.2 g/cc。大體上,自壓碎易碎質塊獲得的粒狀SiC具有基本上相等的表現密度及實際密度,例如,約3.1至3.3 g/cc。For embodiments, the friable mass of SiC preferably and typically has an apparent density that is significantly lower than its actual density, eg, the actual density should be about 3.2 g/cc. In general, granular SiC obtained from crushing friable masses has substantially equal apparent and actual densities, eg, about 3.1 to 3.3 g/cc.

In these examples, such property-enhancing additives would not be considered impurities, as they are intended to be, and if necessary must be, in the final product. Property-enhancing additives may be incorporated into the liquid precursor material. Depending on the nature of the property-enhancing additive, it may be part of the backbone of the precursor, it may be complex, or part of a complex, or it may be incorporated into the liquid precursor, or it may exist in other forms to enable It is preserved (eg, in a form that enables it to function as intended in the final material). Property enhancing additives may also be added to SiC or SiOC powder materials as a coating, may be added as a vapor or gas during processing, or may be in powder form and mixed with polymer derived SiC or SiOC particles, just to name a few. In an embodiment, the property-enhancing additive comprises or is part of a binder for the spatial form. In an embodiment, the property-enhancing additive may be a coating on the spatial form. In addition, the property-enhancing additive should preferably be present in a form and in such a manner that it has the least and preferably no adverse effects on the processing conditions, processing time, and quality of the final product. Thus, polycrystalline silicon oxycarbide derived SiC or SiC steric bodies with greater than 5 nines, greater than 6 nines, and greater than 7 nines may have a substantial presence of property-enhancing additives. These amounts can be from about 0.01% to about 50%, from about 0.1% to about 5%, from about 1% to about 10%, less than 25%, less than 20%, less than 10%, and less than 1%, as well as greater and less Small amounts, depending on the additive and the intended properties it is intended to impart.

Starting raw materials, these differences allow polymer derived ceramic materials to be preformed significantly better in vapor deposition techniques than other SiC sources. Further, it is believed that the spatial shape and vapor deposition techniques of the present invention provide the ability to further benefit from the benefits of ultrapure polymer derived SiC and to synergistically rely on these benefits.

For example, excess carbon can be obtained from formulations with excess C remaining from the PDC route, such as excess C in formulations (e.g., DCPD-type formulations) should yield SiC and SiC as equilibrium phases after complete pyrolysis to >1600°C c. In another embodiment, excess C can be obtained by adding C powder or C-containing species to the liquid PDC formulation prior to curing and pyrolysis. In another embodiment, SiOC pigments with excess free C can be added to the spacers. Further, a binder that decomposes into C in wafer formation may be used. Additionally, C-containing powders are combined with binders to incorporate more C into the formulation.

若需要較大強度,則SiC空間形體可在使用之前經處理用於高溫燒結操作(諸如熱壓或熱等靜壓)。此種操作趨向於提供較低多孔性結構,例如,多孔性<20%。If greater strength is required, the SiC spacers can be processed for high temperature sintering operations (such as hot pressing or hot isostatic pressing) before use. Such manipulations tend to provide lower porosity structures, eg, <20% porosity.

General process for obtaining polycrystalline silicon oxycarbide precursors

典型地,聚合物衍生陶瓷前驅物調配物、及尤其多晶碳氧矽前驅物調配物可通常藉由三種類型之製程來製成,儘管可利用其他製程、及該些製程之變化及組合。該些製程通常涉及將前驅物組合來形成前驅物調配物。一種類型之製程通常涉及較佳地在無溶劑製程中將前驅物材料混合在一起而基本上無化學反應發生,例如,「混合製程」。其他類型之製程通常涉及化學反應,例如,「反應型製程」以形成特定,例如,客製的前驅物調配物,其可為單體、二聚體、三聚體及聚合物。第三類型之製程在無溶劑環境中具有兩種或兩種以上組分的化學反應,例如,「反應摻合型製程」。通常,在混合製程中,基本上所有及較佳地所有化學反應在後續處理期間發生,諸如在固化、熱解及兩者期間發生。Typically, polymer derived ceramic precursor formulations, and in particular polycrystalline silicon oxycarbide precursor formulations, can generally be made by three types of processes, although other processes, and variations and combinations of these processes can be utilized . These processes generally involve combining precursors to form a precursor formulation. One type of process generally involves mixing precursor materials together, preferably in a solvent-free process, with substantially no chemical reaction occurring, eg, a "hybrid process." Other types of processes generally involve chemical reactions, eg, "reactive processes" to form specific, eg, customized precursor formulations, which can be monomers, dimers, trimers, and polymers. The third type of process involves the chemical reaction of two or more components in a solvent-free environment, for example, "reactive blending process". Typically, in a hybrid process, substantially all and preferably all of the chemical reactions occur during subsequent processing, such as during curing, pyrolysis, and both.

應理解,該些術語—反應型製程、反應摻合型製程、及混合型製程—係出於方便起見且作為速記參考。該些術語,亦即,製程類型不為且不應視為限制。例如,反應型製程可用於產生前驅物材料,其隨後與另一前驅物材料用於混合型製程。It should be understood that these terms—reactive process, reactive blending process, and hybrid process—are used for convenience and as shorthand references. These terms, ie, process type are not and should not be considered limiting. For example, a reactive process can be used to generate a precursor material that is then used in a hybrid process with another precursor material.

該些製程類型係以其各別標題描述於本說明書中以及其他處。應理解,以一個標題對一個製程的教示及以其他標題對其他製程的教示可彼此適用,以及適用於本說明書中之其他部分、實施例及教示內容,且反之亦然。用於一種類型之製程的起始或前驅物材料可用於其他類型之製程。進一步,應理解,以該些標題描述的製程應在上下文中利用本說明書之整體來解讀,包括各種實例及實施例。These process types are described under their respective headings in this specification and elsewhere. It should be understood that teachings of one process under one heading and teachings of other processes under other headings are applicable to each other, as well as to other parts, examples, and teachings in this specification, and vice versa. Starting or precursor materials used in one type of process can be used in other types of process. Further, it should be understood that the processes described under these headings are to be read in context with this specification as a whole, including the various examples and embodiments.

應理解,該些製程之組合及變化可用於達成前驅物調配物,及達成中間物、終點產物、及最終產物。取決於特定製程及產品之所要特徵,用於一種製程類型的前驅物及起始材料可用於其他製程類型。來自混合型製程之調配物可在反應型製程或反應摻合型製程中用作前驅物、或組分。類似地,來自反應型製程之調配物可用於混合型製程及反應摻合製程。類似地,來自反應摻合型製程之調配物可用於混合型製程及反應型製程。因此且較佳地,來自其他製程之最佳效能及特徵可加以組合且用來提供成本有效及高效的製程及終點產物。該些製程提供大的靈活性來產生用於中間物、終點產物、及最終產物之客製特徵,且因此,該些製程之任何製程及其組合可提供特定預定產品。在選擇何種類型之製程為較佳時,可考慮諸如成本、可控制性、儲存壽命、按比例放大、製造簡易性等等之因素。It is understood that combinations and variations of these processes can be used to arrive at precursor formulations, and to arrive at intermediates, end products, and final products. Precursors and starting materials used in one process type may be used in other process types depending on the desired characteristics of the particular process and product. Formulations from hybrid processes can be used as precursors, or components, in reactive or reactive blending processes. Similarly, formulations from reactive processes can be used in hybrid and reactive blending processes. Similarly, formulations from reactive blending processes can be used in hybrid and reactive processes. Thus and preferably, the best properties and features from other processes can be combined and used to provide a cost-effective and efficient process and end product. These processes provide great flexibility to produce custom features for intermediates, end products, and final products, and thus, any of these processes and combinations thereof can provide a specific intended product. Factors such as cost, controllability, shelf life, scale-up, ease of manufacture, etc. may be considered in selecting which type of process is preferred.

前驅物調配物可用以形成「純淨」材料(「純淨」材料係意指所有及基本上所有結構係由前驅物材料或未填充調配物製得;及因此,例如,不存在填料或加強物)。前驅物調配物可用以形成經填充材料,其例如具有除前驅物之外的添加劑或其他材料。其可用以形成複合材料,例如,在其中具有諸如加強物的其他材料之結構或塗層。其可用以形成非加強材料,其為主要、基本上、及較佳地僅由前驅物材料製得的材料,該等前驅物材料例如填充最少的材料,其中填料不意欲增加或增進強度;及未填充材料。其可用於形成加強材料,例如具有纖維或其他材料來增加強度、耐磨性、耐久性、或其他特徵或性質之材料,該等性質通常在廣義上視為強度相關的。Precursor formulations can be used to form "pure" materials ("pure" material means that all and substantially all structures are made from precursor materials or unfilled formulations; and thus, for example, no fillers or reinforcements are present) . Precursor formulations may be used to form filled materials, for example, with additives or other materials other than the precursors. It can be used to form composite materials, for example, structures or coatings with other materials such as reinforcements therein. It can be used to form a non-reinforcing material, which is a material made primarily, substantially, and preferably only from precursor materials, such as minimally filled materials, where the filler is not intended to add or enhance strength; and Unfilled material. It can be used to form reinforced materials, such as materials having fibers or other materials to add strength, wear resistance, durability, or other characteristics or properties generally considered to be strength related in a broad sense.

通常,填料材料之類型包括例如:惰性填料,諸如在固化、熱解或使用期間不與SiOC基質反應的無機材料;反應性填料,諸如在固化、熱解、使用、或該些者之組合期間與SiOC基質反應的鋯、氫氧化鋁、及硼化合物;及,活性填料,諸如在終點產物之使用期間釋放以為彼產物提供特定特徵的材料,例如,潤滑劑。填料可歸入一種以上的該些類型。Typically, types of filler materials include, for example: inert fillers, such as inorganic materials that do not react with the SiOC matrix during curing, pyrolysis, or use; reactive fillers, such as during curing, pyrolysis, use, or combinations thereof Zirconium, aluminum hydroxide, and boron compounds reacted with the SiOC matrix; and, active fillers, such as materials released during the use of the end product to provide specific characteristics to that product, eg, lubricants. Fillers may fall into more than one of these types.

填料材料亦可由與已形成為固化或熱解固體之調配物相同的材料製得或來源於該材料,或其可由已形成為固化固體或半固體、或熱解固體的不同前驅物調配物材料。The filler material may also be made from or derived from the same material as the formulation that has been formed as a cured or pyrolyzed solid, or it may be derived from a different precursor formulation material that has been formed as a cured solid or semi-solid, or a pyrolyzed solid. .

多晶碳氧矽調配物及由彼調配物衍生或製得的產物可具有金屬及金屬錯合物。因此,作為氧化物、碳化物或矽化物之金屬可以受控方式引入前驅物調配物中,且因此引入二氧化矽基質中。例如,過渡金屬之有機金屬、金屬鹵化物(氯化物、溴化物、碘化物)、金屬烷氧化物及金屬醯胺化合物可在二氧化矽基質中經由併入前驅物調配物中來共聚。Polycrystalline silicon oxycarbide formulations and products derived or made from such formulations may have metals and metal complexes. Thus, metals as oxides, carbides or silicides can be introduced in a controlled manner into the precursor formulation, and thus into the silica matrix. For example, organometallics of transition metals, metal halides (chlorides, bromides, iodides), metal alkoxides, and metal amide compounds can be copolymerized in a silica matrix by incorporation into the precursor formulation.

填料材料可賦予、調節或增進例如以下各項之特徵及性質:電阻、磁能力、能帶隙特徵、p-n接面特徵、P型特徵、N型特徵、摻雜劑、導電率、半導體特徵、抗靜電性、光學性質(例如,反射率、折射係數及暈彩)、化學電阻率、耐腐蝕性、耐磨性、抗磨性、熱絕緣、UV穩定性、UV保護性、及可在終點產物或材料中可為合乎需要、必需、及二者兼有的其他特徵或性質。The filler material can impart, adjust or enhance the characteristics and properties of the following items such as: resistance, magnetic ability, energy bandgap characteristics, p-n junction characteristics, P-type characteristics, N-type characteristics, dopants, conductivity, semiconductor characteristics, Antistatic properties, optical properties (e.g., reflectivity, refractive index, and iridescence), chemical resistivity, corrosion resistance, abrasion resistance, abrasion resistance, thermal insulation, UV stability, UV protection, and end point Other features or properties in a product or material that may be desirable, necessary, and both.

因此,填料材料可包括銅鉛絲、熱導電填料、導電填料、鉛、光纖、陶瓷著色劑、顏料、氧化物、染料、粉末、陶瓷細料、聚合物衍生陶瓷粒子、孔隙成形劑、碳氧矽烷(carbosilane)、矽烷、矽氮烷、碳化矽、碳氧矽氮烷(carbosilazane)、矽氧烷、金屬粉末、陶瓷粉末、金屬、金屬錯合物、碳、纖維束、纖維、切斷纖維、含硼材料、研磨纖維、玻璃、玻璃纖維、纖維玻璃、及奈米結構(包括前述各項之奈米結構),僅舉幾例。例如,可將壓碎的聚合物衍生陶瓷粒子,例如,細料或珠粒添加至多晶碳氧矽調配物且隨後固化以形成經填充的固化塑膠材料,其具有作為塗層或在裝置或裝置之部件中的顯著防火性質。Thus, filler materials may include copper lead wires, thermally conductive fillers, conductive fillers, lead, optical fibers, ceramic colorants, pigments, oxides, dyes, powders, ceramic fines, polymer derived ceramic particles, pore formers, carboxysilanes (carbosilane), silane, silazane, silicon carbide, carbosilazane, siloxane, metal powder, ceramic powder, metal, metal complex, carbon, fiber bundle, fiber, chopped fiber, Boron-containing materials, milled fibers, glass, glass fibers, fiberglass, and nanostructures (including nanostructures of the foregoing), to name a few. For example, crushed polymer-derived ceramic particles, e.g., fines or beads, can be added to the polycrystalline oxycarbide formulation and subsequently cured to form a filled cured plastic material that has Significant fire protection properties in the components.

多晶碳氧矽前驅物調配物可與加強材料一起使用來形成複合層或塗層。因此,例如,調配物可流動至、浸漬至、吸收於或以其他方式組合以薄的加強材料,諸如碳纖維、玻璃纖維、梭織物、非織物、圓錐形纖維、纖維、繩、編織結構、陶瓷粉末、玻璃粉末、碳粉末、石墨粉末、陶瓷纖維、金屬粉末、碳化物團塊或部件、切斷纖維、纖維束、上述各項之奈米結構、PDC、滿足製程及終點產物之溫度要求的任何其他材料、及該些材料之組合及變化。因此,例如,加強材料可為當前與現存塑膠及陶瓷複合材料一起使用或能夠與之一起使用的任何耐高溫加強材料。另外,因為多晶碳氧矽前驅物調配物可經調配用於較低溫度固化(例如,SATP)或例如約37.8℃(100°F)至約204.4℃(400°F)之固化溫度,所以加強材料可為聚合物、有機聚合物,諸如耐綸、聚丙烯、及聚乙烯,以及芳綸纖維,諸如NOMEX或KEVLAR。The polycrystalline silicon oxycarbide precursor formulations can be used with reinforcing materials to form composite layers or coatings. Thus, for example, the formulation can be flowed onto, impregnated into, absorbed into, or otherwise combined with thin reinforcing materials such as carbon fibers, fiberglass, wovens, non-wovens, conical fibers, fibers, ropes, braided structures, ceramics Powder, glass powder, carbon powder, graphite powder, ceramic fiber, metal powder, carbide agglomerates or parts, chopped fibers, fiber bundles, nanostructures of the above, PDC, to meet the temperature requirements of the process and end products Any other materials, and combinations and variations of these materials. Thus, for example, the reinforcement material may be any high temperature resistant reinforcement material currently used or capable of being used with existing plastic and ceramic composite materials. Additionally, because the polysilicon oxycarbide precursor formulations can be formulated for lower temperature cure (e.g., SATP) or cure temperatures such as about 37.8°C (100°F) to about 204.4°C (400°F), Reinforcing materials can be polymers, organic polymers such as nylon, polypropylene, and polyethylene, and aramid fibers such as NOMEX or KEVLAR.

Although competing, fillers and reinforcements can be added to the formulation.

在混合調配物中,足夠的時間應用於允許前驅物變得有效混合及分散。通常,約15分鐘至一小時之混合為足夠的。典型地,前驅物調配物為相對的,且基本上為剪切不敏感的,且因此泵或混合之類型不為關鍵的。進一步應注意,在較高黏度調配物中,可需要另外的混合時間。在混合期間,調配物之溫度應較佳地保持低於約45℃、及較佳地約10℃。(應注意,該些混合條件係用於預催化調配物。) 反應型製程 In mixed formulations, sufficient time is used to allow the precursors to become effectively mixed and dispersed. Usually, about 15 minutes to one hour of mixing is sufficient. Typically, the precursor formulations are relatively and essentially shear insensitive, and thus the type of pumping or mixing is not critical. It should further be noted that in higher viscosity formulations, additional mixing time may be required. During mixing, the temperature of the formulation should preferably be kept below about 45°C, and preferably about 10°C. (It should be noted that these mixing conditions are for precatalyzed formulations.) reactive process

This process provides the ability to build custom precursor formulations that, when cured, provide plastics with unique and desirable characteristics. Cured materials can also be pyrolyzed to form ceramics with unique characteristics. Reactive processes allow for a predetermined balance of different types of functionality in the end product by selecting functional groups for incorporation into the polymers making up the precursor formulation, such as phenyl groups, which are typically not used in Ceramic but has the benefit of being used to provide high temperature capabilities to plastics; and Styrene which typically does not provide high temperature characteristics to plastics but provides the benefits of ceramics.

R 1 and R 2 may be the same or different. A custom precursor polymer may have several different polymer units, e.g., A1 , A2 , An , and may include as many as 10, 20 or more units, or it may contain only a single unit, For example, MHF made by the reaction process may have only a single unit.

實施例可包括前驅物,其尤其包括三乙氧基甲基矽烷、二乙氧基甲基苯基矽烷、二乙氧基甲烷氫化矽烷、二乙氧基甲基乙烯基矽烷、二甲基乙氧基乙烯基矽烷、二乙氧基二甲基矽烷、乙氧基二甲基苯基矽烷、二乙氧基二氫化矽烷、三乙氧基苯基矽烷、二乙氧基氫化三甲基矽氧烷、二乙氧基甲基三甲基矽氧烷、三甲基乙氧基矽烷、聯苯二乙氧基矽烷、二甲基乙氧基氫化矽氧烷、及該些及其他前驅物之組合及變化,包括本說明書中闡述的其他前驅物。Embodiments may include precursors including, among others, triethoxymethylsilane, diethoxymethylphenylsilane, diethoxymethanehydrosilane, diethoxymethylvinylsilane, dimethylethylsilane, Oxyvinylsilane, Diethoxydimethylsilane, Ethoxydimethylphenylsilane, Diethoxydihydrosilane, Triethoxyphenylsilane, Diethoxyhydrotrimethylsilane oxane, diethoxymethyltrimethicone, trimethylethoxysilane, biphenyldiethoxysilane, dimethylethoxyhydridosiloxane, and these and other precursors Combinations and variations thereof, including other precursors described in this specification.

端部單元Si端1及Si端2可來自二甲基乙氧基乙烯基矽烷、乙氧基二甲基苯基矽烷、及三甲基乙氧基矽烷之前驅物。另外,若聚合製程受適當控制,則羥基封端物可自用於提供聚合物之重複單元的前驅物獲得。The end units Si-terminal 1 and Si-terminal 2 can be derived from dimethylethoxyvinylsilane, ethoxydimethylphenylsilane, and trimethylethoxysilane precursors. In addition, if the polymerization process is properly controlled, hydroxyl-terminated species can be obtained from the precursors used to provide the repeating units of the polymer.

通常,將前驅物添加至具有乙醇(或其他材料以吸收熱,例如,提供熱質量)、過量水、及鹽酸(或其他質子源)之容器。此混合物係加熱直至其達到其活化能,在此之後反應典型地為放熱的。通常,在此反應中,水與前驅物單體之矽烷之乙氧基反應,從而形成羥基(其中乙醇作為副產物)。一旦形成,此羥基變成經受與另一前驅物單體之矽上的乙氧基之反應,從而產生聚合反應。此聚合反應繼續直至建構所要鏈長。Typically, the precursors are added to a vessel with ethanol (or other material to absorb heat, eg, provide thermal mass), excess water, and hydrochloric acid (or other source of protons). This mixture is heated until it reaches its activation energy, after which time the reaction is typically exothermic. Typically, in this reaction, water reacts with the ethoxy groups of the silane of the precursor monomer to form hydroxyl groups (with ethanol as a by-product). Once formed, this hydroxyl group becomes subject to a reaction with an ethoxy group on the silicon of another precursor monomer, resulting in polymerization. This polymerization reaction continues until the desired chain length is built.

用於決定鏈長之控制因素尤其為:所選單體(通常,單體越小,在其開始自身纏繞及鍵結之前可添加的更多);反應中引入封端劑的量及點;及水量與添加速率,以及其他。因此,鏈長可為約180 mw (黏度約5 cps)至約65,000 mw (約10,000 cps之黏度)、大於約1000 mw、大於約10,000 mw、大於約50,000 mw及更大。進一步,聚合的前驅物調配物可且典型地確實具有不同分子量之聚合物,其可預定來提供調配物、固化及陶瓷產品效能特徵。The controlling factors used to determine the chain length are, inter alia: the monomer chosen (generally, the smaller the monomer, the more can be added before it starts to wrap itself and bond); the amount and point of introduction of the capping agent in the reaction; and Amount of water vs. rate of addition, among others. Thus, the chain length can be from about 180 mw (viscosity of about 5 cps) to about 65,000 mw (viscosity of about 10,000 cps), greater than about 1000 mw, greater than about 10,000 mw, greater than about 50,000 mw, and greater. Further, polymeric precursor formulations can, and typically do, have polymers of varying molecular weights, which can be predetermined to provide formulation, curing, and ceramic product performance characteristics.

在完成聚合反應之後,將材料轉移至分離設備中,例如,分離漏斗,其具有例如為材料質量的約1.2倍至約1.5倍的去離子水量。將此混合物有力地攪拌約小於1分鐘且較佳地約5至30秒。一旦攪拌,使材料沉降且分離,此可耗費約1至2小時。聚合物為較高密度材料且自容器移除。此移除的聚合物隨後藉由在淺托盤中於90℃下升溫約兩小時;或,較佳地,使其通過擦淨的薄膜蒸餾設備以移除任何殘餘水及乙醇來乾燥。替代地,添加足以緩衝水層至約4至約7之pH的碳酸氫鈉。應進一步理解,可使用自材料混合、反應及分離聚合物之其他及商業方式。After the polymerization reaction is complete, the material is transferred to a separation device, eg, a separation funnel, with an amount of deionized water, eg, about 1.2 to about 1.5 times the mass of the material. This mixture is stirred vigorously for about less than 1 minute and preferably for about 5 to 30 seconds. Once stirred, the material is allowed to settle and separate, which can take about 1 to 2 hours. Polymers are higher density materials and are removed from the container. This removed polymer is then dried by warming at 90°C in shallow trays for about two hours; or, preferably, by passing it through a wiped thin film distillation apparatus to remove any residual water and ethanol. Alternatively, enough sodium bicarbonate is added to buffer the aqueous layer to a pH of about 4 to about 7. It is further understood that other and commercial means of mixing, reacting and isolating polymers from materials may be used.

較佳地,觸媒係用於來自反應型製程的聚合物前驅物調配物之固化製程。可使用如用於固化來自混合型製程的前驅物調配物的相同聚合物。應注意,通常與混合型調配物不同,不必要求觸媒固化反應型聚合物。亦可使用抑制劑。然而,若不使用觸媒,則反應時間及速率將較慢。來自反應製程的固化材料之固化及熱解基本上與來自混合製程及反應摻合製程的固化材料之固化及熱解相同。Preferably, the catalyst is used in the curing process of the polymer precursor formulation from a reactive process. The same polymers as used to cure the precursor formulation from a hybrid process can be used. It should be noted that catalytic curing of reactive polymers is not generally required, unlike hybrid formulations. Inhibitors may also be used. However, if no catalyst is used, the reaction time and rate will be slower. The curing and pyrolysis of cured materials from reactive processes are substantially the same as the curing and pyrolysis of cured materials from hybrid and reactive blending processes.

反應型製程可在眾多類型之氣氛及條件下進行,例如,空氣、惰性氣體、N 2、氬、流動氣體、靜態氣體、減壓、環境壓力、高壓、及該些者之組合及變化。 反應摻合型製程 Reactive processes can be performed under many types of atmospheres and conditions, such as air, inert gas, N2 , argon, flowing gas, static gas, reduced pressure, ambient pressure, high pressure, and combinations and variations of these. reactive blending process

在反應摻合型製程中,前驅物係在不存在溶劑下反應來形成前驅物調配物。例如,反應摻合型製程之實施例具有自MHF及二環戊二烯(Dicyclopentadiene; DCPD)製備的前驅物調配物。使用反應性摻合製程,產生MHF/DCPD聚合物且此聚合物係用作前驅物調配物。其可單獨使用以形成固化或熱解產物,或在混合或反應製程中用作前驅物。In reactive blending processes, precursors are reacted in the absence of a solvent to form a precursor formulation. For example, an embodiment of a reactive blending process has a precursor formulation prepared from MHF and Dicyclopentadiene (DCPD). Using a reactive incorporation process, MHF/DCPD polymers are produced and used as precursor formulations. They can be used alone to form cured or pyrolyzed products, or as precursors in mixing or reaction processes.

因此,例如,可使用具有已知分子量及氫化物當量質量的約40至90% MHF;約0.20 wt% P01觸媒;及具有≥ 83%純度的約10至60% DCPD。Thus, for example, about 40 to 90% MHF of known molecular weight and hydride equivalent mass; about 0.20 wt% PO1 catalyst; and about 10 to 60% DCPD with > 83% purity can be used.

P01為在四乙烯基環四矽氧烷中的2% Pt(0)四乙烯基環四矽氧烷錯合物,其利用四乙烯基環四矽氧烷稀釋20倍至0.1 %之Pt(0)錯合物。以此方式,每1%負荷之主體觸媒提供10 ppm Pt。P01 is a 2% Pt(0) tetravinylcyclotetrasiloxane complex in tetravinylcyclotetrasiloxane diluted 20-fold with tetravinylcyclotetrasiloxane to 0.1% Pt( 0) Complexes. In this way, 10 ppm Pt was provided per 1% loading of the host catalyst.

在製程之實施例中,具有混合器之可密封反應容器可用於反應。反應係在密封容器中,在空氣中進行;儘管可使用其他類型之氣氛。較佳地,反應係在大氣壓力下進行,但可使用較高及較低壓力。另外,反應摻合型製程可在眾多類型之氣氛及條件下進行,例如,空氣、惰性氣體、N 2、氬、流動氣體、靜態氣體、減壓、環境壓力、高壓、及該些者之組合及變化。 In an embodiment of the process, a sealable reaction vessel with a mixer can be used for the reaction. Reactions were performed in air in sealed containers; although other types of atmospheres could be used. Preferably, the reaction is carried out at atmospheric pressure, although higher and lower pressures can be used. In addition, reactive blending processes can be performed under numerous types of atmospheres and conditions, such as air, inert gas, N2 , argon, flowing gas, static gas, reduced pressure, ambient pressure, high pressure, and combinations of these and changes.

在實施例中,將850公克之MHF (總聚合物混合物之85%)添加至反應容器且加熱至約50℃。一旦達到此溫度,即將加熱器關閉,且將0.20% (以MHF之重量計)之P01鉑觸媒添加至反應容器中之MHF。典型地,在添加觸媒之後,氣泡將形成且溫度將最初上升大致2-20℃。In an example, 850 grams of MHF (85% of the total polymer mixture) was added to the reaction vessel and heated to about 50°C. Once this temperature was reached, the heater was turned off and 0.20% (by weight of MHF) of P01 platinum catalyst was added to the MHF in the reaction vessel. Typically, after catalyst addition, gas bubbles will form and the temperature will initially rise by approximately 2-20°C.

當溫度開始下降時,將約150 g之DCPD (總聚合物混合物之15 wt%)添加至反應容器。溫度可下降另一量,例如,約5-7℃。When the temperature started to drop, about 150 g of DCPD (15 wt% of the total polymer mixture) was added to the reaction vessel. The temperature may drop another amount, for example, about 5-7°C.

在此點,在反應製程中,反應容器之溫度經控制以隨時間維持預定溫度分佈,且管理可伴隨放熱的溫度增加。較佳地,反應容器之溫度在製程全程經調節、監視及控制。In this regard, during the reaction process, the temperature of the reaction vessel is controlled to maintain a predetermined temperature profile over time, and to manage a temperature increase that may be accompanied by an exotherm. Preferably, the temperature of the reaction vessel is adjusted, monitored and controlled throughout the process.

在反應製程之MHF/DCPD實施例之實施例中,溫度分佈可如下:使溫度達到約80℃(可耗費約15-40 min,其取決於所存在的材料量);溫度隨後將增加且在約104℃處為峰值,一旦溫度開始下降,將加熱器設定溫度增加至100℃且反應混合物之溫度經監視以確保聚合物溫度保持高於80℃歷時最少總共約2小時及最大總共約4小時。在高於80℃2-4小時之後,將加熱器關閉,且將聚合物冷卻至環境溫度。應瞭解,在較大及較小分批、連續、半連續、及其他類型製程中,溫度及時間分佈可為不同的。In an embodiment of the MHF/DCPD embodiment of the reaction process, the temperature profile may be as follows: bring the temperature to about 80°C (it may take about 15-40 min, depending on the amount of material present); the temperature will then increase and at There is a peak at about 104°C, once the temperature begins to drop, the heater set point is increased to 100°C and the temperature of the reaction mixture is monitored to ensure that the polymer temperature remains above 80°C for a minimum of about 2 hours total and a maximum of about 4 hours total . After 2-4 hours above 80°C, the heater was turned off and the polymer was cooled to ambient temperature. It should be appreciated that temperature and time profiles may be different in larger and smaller batch, continuous, semi-continuous, and other types of processes.

在較大規模及商業操作中,可使用分批、連續、及該些者之組合。工業工廠自動化及控制系統可用於控制反應、在反應期間的溫度分佈及其他過程。In larger scale and commercial operations, batch, continuous, and combinations of these can be used. Industrial plant automation and control systems can be used to control reactions, temperature distribution during reactions, and other processes.

在上表中,「聚合度」為附接在一起以形成聚合物的單體單元或重複單元之數量。「當量_/mol」係指莫耳當量。「乙烯基之公克/莫耳」係指提供1莫耳當量之乙烯基官能性所需的給定聚合物之量。「VMH」係指甲基乙烯基流體、來自乙氧基製程之直鏈乙烯基材料,其可替代TV。VT之數字「0200」等為對彼特定VT而言以厘泊計的黏度(例如,0200 = 200 cps)。 固化及熱解 In the table above, "degree of polymerization" is the number of monomeric or repeating units that are attached together to form a polymer. "Equivalent_/mol" means molar equivalent. "Gram/mole of vinyl" refers to the amount of a given polymer required to provide 1 mole equivalent of vinyl functionality. "VMH" refers to Methyl Vinyl Fluid, a linear vinyl material from an ethoxy process, which is an alternative to TV. The number "0200" etc. for a VT is the viscosity in centipoise for that particular VT (eg, 0200 = 200 cps). Curing and Pyrolysis

包括來自上文類型之製程以及其他製程的多晶碳氧矽前驅物調配物的前驅物調配物可固化以形成固體、半固體、或塑膠類材料。典型地,將前驅物調配物展布、成形、或以其他方式形成為預成型件,其將包括任何空間結構或形體,包括薄膜及厚膜。在固化中,多晶碳氧矽前驅物調配物可經由初始固化處理,以提供部分固化材料,其亦可例如稱為預成型件,生料、或生固化物(不暗示有關材料顏色之任何內容)。生料可隨後經進一步固化。因此,可使用一或多個固化步驟。材料可經「終點固化」,亦即,固化至材料具有用於其所欲目的的必要實體強度及其他性質的點。固化之量可達最終固化(或「硬固化」),亦即,所有或基本上所有化學反應已停止的點(如例如藉由在材料中不存在反應性基團所量測的,亦即,所有反應已停止,或反應性基團隨時間減少趨於平衡,亦即,基本上所有反應已停止)。因此,材料可固化至變化程度,此取決於其所欲用途及目的。例如,在一些情形中,終點固化及硬固化可為相同的。諸如氣氛及溫度之固化條件可實現固化材料之組成。Precursor formulations including polycrystalline silicon oxycarbide precursor formulations from processes of the above type, as well as others, can be cured to form solid, semi-solid, or plastic-like materials. Typically, the precursor formulation is spread, shaped, or otherwise formed into a preform, which will include any spatial structure or shape, including thin and thick films. In curing, the polycrystalline silicon oxycarbide precursor formulation may be subjected to an initial cure process to provide a partially cured material, which may also be referred to, for example, as a preform, green, or green cure (without implying any reference to the color of the material). content). The green mass can then be further cured. Thus, one or more curing steps may be used. The material may be "end-cured," that is, cured to the point where the material has the necessary physical strength and other properties for its intended purpose. The amount of cure is up to final cure (or "hard cure"), that is, the point at which all or substantially all chemical reactions have ceased (as measured, for example, by the absence of reactive groups in the material, i.e. , all reactions have ceased, or the reactive groups decrease over time towards equilibrium, ie substantially all reactions have ceased). Thus, the material can be cured to varying degrees, depending on its intended use and purpose. For example, in some cases the endpoint cure and hard cure may be the same. Curing conditions such as atmosphere and temperature can achieve the composition of the cured material.

在多層或複合結構及形體中,多晶碳氧矽材料之層可固化至變化程度,例如,在多層實施例中,層可經生固化以促進層黏著,隨後最終固化至硬固化物。在多層結構中之每一層可固化至相同固化程度,至不同固化程度,經受一個、兩個、三個或更多個固化步驟,及該些者之組合及變化。In multilayer or composite structures and shapes, layers of polycrystalline silicon oxycarbide material may be cured to varying degrees, for example, in multilayer embodiments, the layers may be green cured to promote layer adhesion followed by final cure to a hard set. Each layer in a multilayer structure can be cured to the same degree of cure, to a different degree of cure, subjected to one, two, three or more curing steps, and combinations and variations of these.

固化可在標準環境溫度及壓力下(「SATP」,1個大氣壓,25℃)、在高於或低於彼溫度的溫度下、在高於或低於彼壓力的壓力下、及歷經變化的時間段進行。固化可經由各種加熱、加熱速率、及溫度分佈(例如,保持時間及溫度、連續溫度變化、循環溫度變化,例如,加熱繼之以維持、冷卻、再加熱等等)來進行。用於固化之時間可為幾秒(例如,小於約1秒、小於5秒),至小於一分鐘,至數分鐘,至數小時,至數天(或可能更長)。固化亦可在任何類型之周圍環境中進行,包括例如,氣體、液體、空氣、水、含表面活性劑之液體、惰性氣氛、N 2、氬、流動氣體(例如,掃掠氣)、靜態氣體、減壓O 2(例如,低於大氣壓的O 2量,諸如小於20% O 2、小於15% O 2、小於10% O 2、小於5% O 2)、減壓(例如,小於大氣壓)、高壓(例如,大於大氣壓)、富集的O 2(例如,大於大氣壓的O 2量)、環境壓力、受控分壓及該些及其他處理條件之組合及變化。 Curing can be at standard ambient temperature and pressure ("SATP", 1 atmosphere, 25°C), at temperatures above or below that temperature, at pressures above or below that pressure, and over varying time period. Curing can be performed via various heating, heating rates, and temperature profiles (eg, hold times and temperatures, continuous temperature changes, cyclic temperature changes, eg, heating followed by holding, cooling, reheating, etc.). The time for curing can range from seconds (eg, less than about 1 second, less than 5 seconds), to less than a minute, to minutes, to hours, to days (or possibly longer). Curing can also be performed in any type of ambient environment including, for example, gas, liquid, air, water, surfactant-containing liquid, inert atmosphere, N2 , argon, flowing gas (e.g., sweep gas), static gas , reduced O2 (e.g., an amount of O2 below atmospheric pressure, such as less than 20% O2 , less than 15% O2 , less than 10% O2 , less than 5% O2 ), reduced pressure (e.g., less than atmospheric pressure) , high pressure (eg, greater than atmospheric pressure), enriched O2 (eg, greater than atmospheric O2 amount), ambient pressure, controlled partial pressure, and combinations and variations of these and other processing conditions.

在實施例中,固化環境,例如,熔爐、氣氛、容器及該些者之組合及變化可具有貢獻於或實現例如預成型件、固化材料、陶瓷及最終應用或產品中之組成、催化、化學計量、特徵、效能及該些者之組合及變化的材料。In embodiments, the curing environment, e.g., furnace, atmosphere, vessel, and combinations and variations of these can have a contribution to or enable, for example, compositional, catalytic, chemical Materials of measurement, characteristics, performance and combinations and variations of these.

對於高純度材料,熔爐、容器、操縱儀器、氣氛、及固化設備及製程之其他部件為清潔的,基本上不含且不貢獻將認為是固化材料之雜質或污染物的任何元素或材料。For high purity materials, furnaces, vessels, manipulators, atmospheres, and other components of curing equipment and processes are clean, substantially free of and do not contribute to any element or material that would be considered an impurity or contamination of the curing material.

較佳地,在固化製程之實施例中,固化係發生在以下範圍內之溫度下:約5℃或更大、約20℃至約250℃、約20℃至約150℃、約75℃至約125℃、及約80℃至90℃。然而可使用較高及較低溫度及各種加熱分佈(例如,隨時間的溫度變化率(「勻變速率」,例如,∆度/時間)、保持時間、及溫度)。Preferably, in embodiments of the curing process, curing occurs at a temperature in the range of about 5°C or greater, about 20°C to about 250°C, about 20°C to about 150°C, about 75°C to About 125°C, and about 80°C to 90°C. However, higher and lower temperatures and various heating profiles (eg, rate of temperature change over time ("ramp rate", eg, Δ°/time), hold time, and temperature) can be used.

例如溫度、時間、勻變速率之固化條件可取決於且在一些實施例中可整體或部分地藉由調配物預定以匹配例如預成型件之大小、預成型件之形體、或保持預成型件以防止應力開裂、廢氣、或與固化製程相關聯其他現象的模。進一步,固化條件可使得較佳地以受控方式利用先前可能已察覺為與固化製程相關聯的問題的事物。因此,例如,廢氣可用以產生具有開口或閉合結構之泡沫材料。類似地,固化條件可用於產生或控制材料之微結構及奈米結構。通常,固化條件可用於影響、控制或改質製程之動力學及熱力學,從而可影響形態學、效能、特徵及功能,以及其他。Cure conditions such as temperature, time, ramp rate may depend on and in some embodiments may be predetermined in whole or in part by the formulation to match, for example, the size of the preform, the shape of the preform, or hold the preform Molds to prevent stress cracking, outgassing, or other phenomena associated with the curing process. Further, the curing conditions may be such that what may have previously been perceived as problems associated with the curing process can be exploited in a preferably controlled manner. Thus, for example, exhaust gases can be used to generate foams with open or closed structures. Similarly, curing conditions can be used to create or control the microstructure and nanostructure of the material. In general, curing conditions can be used to influence, control or modify the kinetics and thermodynamics of the process, which can affect morphology, performance, characteristics and function, among others.

在固化多晶碳氧矽前驅物調配物之後,發生交聯反應,其在一些實施例中提供尤其具有例如-R 1-Si-C-C-Si-O-Si-C-C-Si-R 2-之交聯結構,其中R 1及R 2取決於及基於用於調配物中之前驅物變化。在固化材料之實施例中,其可具有交聯結構,具有與另一矽原子之3配位矽中心,其藉由在矽原子之間少於5個原子分離。然而涵蓋固化材料之另外的其他結構及類型。因此,例如,Luperox 231之使用可自相同單體產生結構,其為-Si-C-C-C-Si-。當使用其他交聯劑時,例如,DCPD及二乙烯基苯,矽原子之間的碳原子數量將大於5個原子。交聯,例如,固化材料之一些實施例的通式將為-Si-R 3-Si-,其中R 3將為乙基(例如來自乙烯基前驅物)、丙基(例如來自烯丙基前驅物)、二環戊烷(例如來自DCPD前驅物)、降莰烷(例如來自降莰二烯前驅物)、二乙基苯(例如來自二乙烯基苯前驅物)、及其他。 After curing the polycrystalline silicon oxycarbide precursor formulation, a crosslinking reaction occurs, which in some embodiments provides a compound having, for example, -R 1 -Si-CC-Si-O-Si-CC-Si-R 2 - among others. Cross-linked structures where R1 and R2 depend on and vary based on the precursors used in the formulation. In an embodiment of the cured material, it may have a cross-linked structure with a 3-coordinated silicon center to another silicon atom separated by less than 5 atoms between the silicon atoms. Still other structures and types of cured materials are contemplated, however. Thus, for example, the use of Luperox 231 can result in a structure from the same monomer, which is -Si-CCC-Si-. When using other crosslinkers, such as DCPD and divinylbenzene, the number of carbon atoms between silicon atoms will be greater than 5 atoms. Crosslinking, for example, the general formula of some embodiments of the cured material will be -Si- R3 -Si-, where R3 will be ethyl (eg from a vinyl precursor), propyl (eg from an allyl precursor species), dicyclopentane (eg, from DCPD precursors), norbornane (eg, from norbornadiene precursors), diethylbenzene (eg, from divinylbenzene precursors), and others.

在固化製程期間,一些調配物可展現放熱,亦即,自加熱反應,其可產生少量熱來輔助或驅動固化反應,或可產生大量熱,其可需要加以管理並移除以便避免諸如應力破裂之問題。在固化期間,典型地發生排廢氣且產生材料損失,此損失係通常藉由剩餘材料之量,例如,固化產率來定義。本發明之實施例的調配物、固化條件、及多晶碳氧矽前驅物調配物之實施例可具有至少約90%、約92%、約100%之固化產率。事實上,利用空氣固化時,材料可具有高於100%,例如,約101-105%之固化產率,其係由於自空氣吸收的氧。另外,在固化期間,材料典型地收縮,此收縮可取決於預成型形體之調配物、固化條件、及性質,及預成型件是否為加強、填充、純或未加強的,收縮約20%、小於20%、小於約15%、小於約5%、小於約1%、小於約0.5%、小於約0.25%及更小。During the curing process, some formulations may exhibit an exothermic, i.e., self-heating reaction, which may generate a small amount of heat to aid or drive the curing reaction, or a large amount of heat, which may need to be managed and removed to avoid conditions such as stress cracking question. During curing, outgassing typically occurs and a loss of material occurs, which is usually defined by the amount of remaining material, eg, the curing yield. Embodiments of formulations, curing conditions, and polycrystalline silicon oxycarbide precursor formulations of embodiments of the present invention may have cure yields of at least about 90%, about 92%, about 100%. In fact, when curing with air, the material may have a cure yield higher than 100%, eg, about 101-105%, due to the oxygen absorbed from the air. Additionally, during curing, the material typically shrinks, this shrinkage can be about 20%, depending on the formulation, curing conditions, and nature of the preform, and whether the preform is reinforced, filled, pure, or unreinforced. Less than 20%, less than about 15%, less than about 5%, less than about 1%, less than about 0.5%, less than about 0.25%, and less.

固化可藉由具有必要的溫度及環境控製程度的任何類型之加熱設備、或機制、技術、或形態學來完成。固化可經由例如以下方式來完成:加熱水浴、電爐、微波、煤氣爐、熔爐、強制熱空氣、塔、噴霧乾燥、降膜式反應器、流體化床反應器、間接加熱元件、直接加熱(例如,加熱表面、圓筒、及板)、紅外加熱、UV照射(燈)、RF熔爐、經由高剪切混合之現場持續乳化、經由超音波處理之現場持續乳化、廣譜白光、IR光、相干電磁輻射(例如,雷射,包括可見光、UV及IR)、及對流加熱,僅舉幾例。Curing can be accomplished by any type of heating equipment, or mechanism, technique, or morphology with the necessary degree of temperature and environmental control. Curing can be accomplished via, for example, heated water baths, electric ovens, microwaves, gas ovens, furnaces, forced hot air, towers, spray drying, falling film reactors, fluidized bed reactors, indirect heating elements, direct heating (e.g. , heated surfaces, cylinders, and plates), infrared heating, UV irradiation (lamps), RF furnaces, continuous in-situ emulsification via high-shear mixing, continuous in-situ emulsification via ultrasonic treatment, broad-spectrum white light, IR light, coherent Electromagnetic radiation (eg, laser, including visible light, UV, and IR), and convective heating, to name a few.

在實施例中,對具有足夠量之觸媒的實施例,固化亦可在環境條件下發生。In embodiments, curing may also occur under ambient conditions for embodiments with a sufficient amount of catalyst.

若對一實施例進行熱解,則固化材料可例如加熱至約600℃至約2,300℃;約650℃至約1,200℃、約800℃至約1300℃、約900℃至約1,200℃及約950℃至1,150℃。在該些溫度下,典型地所有有機結構經移除或與無機成分組合以形成陶瓷。典型地,在約650℃至1,200℃範圍中的溫度下,所得材料為非晶形玻璃狀陶瓷。當經加熱高於約1,200℃時,材料典型地可形成奈米結晶結構,或微米結晶結構,諸如SiC、Si 3N 4、SiCN、β SiC,且在高於1,900℃,可形成α SiC結構,且在高於2,200℃,典型地形成α SiC。例如,經熱解的陶瓷材料可為單晶、多晶、非晶形、及該些及其他類型之形態學之組合、變化及子群。 If pyrolysis is performed on an embodiment, the cured material can be heated, for example, to a temperature of about 600°C to about 2,300°C; about 650°C to about 1,200°C; about 800°C to about 1300°C; about 900°C to about 1,200°C; °C to 1,150 °C. At these temperatures, typically all organic structures are removed or combined with inorganic components to form a ceramic. Typically, at temperatures in the range of about 650°C to 1,200°C, the resulting material is an amorphous glass-like ceramic. Materials typically form nanocrystalline structures, or microcrystalline structures, such as SiC, Si3N4 , SiCN, βSiC, and above 1,900°C, alpha SiC structures when heated above about 1,200°C , and above 2,200 °C, α SiC is typically formed. For example, pyrolyzed ceramic materials can be single crystal, polycrystalline, amorphous, and combinations, variations, and subgroups of these and other types of morphologies.

熱解可在不同加熱及環境條件下進行,從而較佳地包括熱控制、動力學控制及該些者之組合及變化,以及其他。例如,熱解可具有各種加熱勻變速率、加熱循環及環境條件。在一些實施例中,溫度可升高,且保持預定溫度以幫助已知轉變(例如,產氣、揮發、分子重排等等)且隨後提高至相應於下一已知轉變的下一保持溫度。熱解可發生在以下各項中:還原氣氛、氧化氣氛、低O 2、富集氣體(例如,火焰內或直接相鄰於火焰)、惰性氣體、N 2、氬、空中、減壓、環境壓力、高壓、流動氣體(例如,掃掠氣,具有例如約15.0 GHSV (氣體時空速度)至約0.1 GHSV、約6.3 GHSV至約3.1 GHSV、及約3.9 GHSV之流動速率)、靜態氣體、及該些者之組合及變化。 Pyrolysis can be performed under different heating and environmental conditions, thereby preferably including thermal control, kinetic control and combinations and variations of these, among others. For example, pyrolysis can have various heating ramp rates, heating cycles, and ambient conditions. In some embodiments, the temperature may be raised and held at a predetermined temperature to aid a known transition (e.g., gassing, volatilization, molecular rearrangement, etc.) and then raised to the next held temperature corresponding to the next known transition . Pyrolysis can occur in the following: reducing atmosphere, oxidizing atmosphere, low O2 , enriched gas (e.g., within a flame or directly adjacent to a flame), inert gas, N2 , argon, air, reduced pressure, ambient Pressure, high pressure, flowing gas (e.g., sweep gas, having flow rates such as about 15.0 GHSV (gas hourly space velocity) to about 0.1 GHSV, about 6.3 GHSV to about 3.1 GHSV, and about 3.9 GHSV), static gas, and the Combinations and variations of these.

在一些實施例中,在熱解之後,石墨烯、石墨、非晶形碳結構及該些者之組合及變化係存在於Si-O-C陶瓷。由SiOxCy結構組成的產生SiO 4、SiO 3C、SiO 2C 2、SiOC 3、及SiC 4之矽物質之分佈係以變化比率形成,該等變化比率係產生自前驅物選擇及其處理歷史。碳通常結合在相鄰碳之間及/或結合至矽原子。通常,在陶瓷狀態中,碳大部分不與氧原子配位,因此氧大部分與矽配位。 In some embodiments, graphene, graphite, amorphous carbon structures, and combinations and variations of these are present in Si-OC ceramics after pyrolysis. The distribution of silicon species consisting of SiOxCy structures yielding SiO4 , SiO3C , SiO2C2 , SiOC3 , and SiC4 is formed at varying rates resulting from the choice of precursors and their processing history. Carbon is usually bonded between adjacent carbons and/or to silicon atoms. In general, in a ceramic state, most of carbon is not coordinated to oxygen atoms, and thus most of oxygen is coordinated to silicon.

熱解可在維持要求溫度及環境控制之任何加熱設備中進行。因此,例如,熱解可利用以下各項來進行:高壓爐、箱式爐、管式爐、晶體生長熔爐、石墨箱式爐、電弧熔化熔爐、感應爐、窯爐、MoSi 2加熱元件熔爐、碳熔爐、真空爐、氣體燃爐、電爐、直接加熱、間接加熱、流體化床、RF熔爐、窯爐、隧道式窯爐、箱式窯爐、梭動窯爐、焦炭型設備、雷射器、微波、其他電磁輻射、及可獲得用於熱解之要求溫度的該些及其他加熱設備及系統之組合及變化。 Pyrolysis can be performed in any heating apparatus that maintains the required temperature and environmental controls. Thus, for example, pyrolysis can be performed using: high pressure furnaces, chamber furnaces, tube furnaces, crystal growth furnaces, graphite chamber furnaces, arc melting furnaces, induction furnaces, kilns, MoSi2 heating element furnaces, Carbon Furnace, Vacuum Furnace, Gas Furnace, Electric Furnace, Direct Heating, Indirect Heating, Fluidized Bed, RF Furnace, Kiln, Tunnel Furnace, Box Furnace, Shuttle Furnace, Coke Type Equipment, Laser , microwaves, other electromagnetic radiation, and combinations and variations of these and other heating equipment and systems that can obtain the desired temperature for pyrolysis.

例如,可用作填充材料之金屬及金屬錯合物將包括可使用的過渡金屬之環戊二烯基化合物。過渡金屬之環戊二烯基化合物可有機化成兩種類型:雙環戊二烯基錯合物;及單環戊二烯基錯合物。環戊二烯基錯合物可包括C 5H 5、C 5Me 5、C 5H 4Me、CH 5R 5(其中R = Me、Et、丙基、異丙基、丁基、異丁基、第二丁基)。在該些情況之任一者中,Si可直接鍵結至環戊二烯基配位體或Si中心可附接至烷基鏈,繼而附接至環戊二烯基配位體。 For example, metals and metal complexes that may be used as filler materials would include cyclopentadienyl compounds of transition metals that may be used. Cyclopentadienyl compounds of transition metals can be organized into two types: dicyclopentadienyl complexes; and monocyclopentadienyl complexes. Cyclopentadienyl complexes may include C5H5 , C5Me5 , C5H4Me , CH5R5 ( where R = Me, Et , propyl , isopropyl, butyl, isobutyl base, second butyl). In either of these cases, the Si can be directly bonded to the cyclopentadienyl ligand or the Si center can be attached to an alkyl chain, which in turn is attached to the cyclopentadienyl ligand.

可與前驅物調配物一起使用且用於產品中的環戊二烯基錯合物可包括以下各項之雙環戊二烯基金屬錯合物:第一列過渡金屬(鈦、釩、鉻、鐵、鈷、鎳);第二列過渡金屬(鋯、鉬、釕、銠、鈀);第三列過渡金屬(鉿、鉭、鎢、銥、鋨、鉑);鑭系(La、Ce、Pr、Nd、Pm、Sm、Eu、Gd、Tb、Dy、Ho);及錒系(Ac、Th、Pa、U、Np)。Cyclopentadienyl complexes that may be used with the precursor formulation and in the product may include dicyclopentadienyl metal complexes of the following: first row transition metals (titanium, vanadium, chromium, iron, cobalt, nickel); second column transition metals (zirconium, molybdenum, ruthenium, rhodium, palladium); third column transition metals (hafnium, tantalum, tungsten, iridium, osmium, platinum); lanthanides (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho); and actinides (Ac, Th, Pa, U, Np).

單環戊二烯基錯合物亦可用於向前驅物調配物提供金屬官能性,且當較佳地利用適當配位體(例如氯化物或羰基)穩定時,將包括以下各項之單環戊二烯基錯合物:第一列過渡金屬(鈦、釩、鉻、鐵、鈷、鎳);第二列過渡金屬(鋯、鉬、釕、銠、鈀);第三列過渡金屬(鉿、鉭、鎢、銥、鋨、鉑)。Monocyclopentadienyl complexes may also be used to provide metal functionality to the precursor formulation and, when preferably stabilized with appropriate ligands such as chloride or carbonyl, would include monocyclic Pentadienyl complexes: transition metals in the first column (titanium, vanadium, chromium, iron, cobalt, nickel); transition metals in the second column (zirconium, molybdenum, ruthenium, rhodium, palladium); transition metals in the third column ( hafnium, tantalum, tungsten, iridium, osmium, platinum).

金屬之烷基錯合物亦可用於向前驅物調配物及產品提供金屬官能性。在該些烷基錯合物中,Si中心具有烷基(乙基、丙基、丁基、乙烯基、丙烯基、丁烯基),其可直接經由σ鍵鍵結至過渡金屬。進一步地,此在利用後期過渡金屬諸如Pd、Rh、Pt、Ir的情況下將更為普遍。Alkyl complexes of metals can also be used to provide metal functionality to precursor formulations and products. In these alkyl complexes, the Si center has an alkyl group (ethyl, propyl, butyl, vinyl, propenyl, butenyl), which can be directly bonded to the transition metal via a σ bond. Further, this will be more prevalent with late transition metals such as Pd, Rh, Pt, Ir.

金屬之配位錯合物亦可用於向前驅物調配物及產品提供金屬官能性。在該些配位錯合物中,Si中心具有不飽和烷基(乙烯基、丙烯基、丁烯基、伸乙醯基、丁二烯基),其可鍵結至Cr、Mo、W、Mn、Re、Fe、Ru、Os、Co、Rh、Ir、Ni羰基錯合物或烯錯合物。Si中心亦可附接至苯基、經取代的苯基或其他芳基化合物(吡啶、嘧啶)且苯基或芳基可位移金屬中心上之羰基。Coordination complexes of metals can also be used to provide metal functionality to precursor formulations and products. In these coordination complexes, the Si center has an unsaturated alkyl group (vinyl, propenyl, butenyl, acetyl, butadienyl), which can be bonded to Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni carbonyl complexes or alkene complexes. The Si center can also be attached to a phenyl, substituted phenyl, or other aryl compound (pyridine, pyrimidine) and the phenyl or aryl can displace the carbonyl on the metal center.

金屬烷氧化物亦可用於向前驅物調配物及產品提供金屬官能性。金屬烷氧化物化合物可與矽前驅物化合物混合且隨後用氫氧化物處理以與聚合物、共聚物同時形成氧化物。此亦可用金屬鹵化物及金屬醯胺來進行。較佳地,此係使用前期過渡金屬連同鋁、鎵及銦,後期過渡金屬:Fe、Mn、Cu,及鹼土金屬:Ca、Sr、Ba、Mg來進行。Metal alkoxides can also be used to provide metal functionality to precursor formulations and products. Metal alkoxide compounds can be mixed with silicon precursor compounds and then treated with hydroxide to form oxides simultaneously with polymers, copolymers. This can also be done with metal halides and metal amides. Preferably, this is done using early transition metals together with aluminum, gallium and indium, late transition metals: Fe, Mn, Cu, and alkaline earth metals: Ca, Sr, Ba, Mg.

其中Si直接鍵結至藉由鹵化物或有機基團穩定的金屬中心的化合物亦可用於向前驅物調配物及產品提供金屬官能性。Compounds in which Si is directly bonded to a metal center stabilized by a halide or organic group can also be used to provide metal functionality to precursor formulations and products.

另外,應理解,金屬及金屬錯合物可在熱解或後續熱處理之後為連續相。調配物可特定地設計來與所選金屬反應以現場形成金屬碳化物、氧化物及其他金屬化合物,通常稱為陶瓷金屬(例如,陶瓷金屬化合物)。調配物可與所選金屬反應以現場形成化合物,諸如富鋁紅柱石、鋁矽酸鹽、及其他。調配物或終點產物中相對於二氧化矽之量的金屬之量可為約0.1莫耳%至99.9莫耳%、約1莫耳%或更大、約10莫耳%或更大、及約20莫耳百分比或更大。金屬與本發明之前驅物式之前述使用可用於控制並提供預定化學計量。 標題及實施例 Additionally, it should be understood that metals and metal complexes may be the continuous phase after pyrolysis or subsequent heat treatment. Formulations can be specifically designed to react with selected metals to form metal carbides, oxides, and other metal compounds in situ, commonly referred to as cermets (eg, cermets). Formulations can react with selected metals to form compounds in situ, such as mullite, aluminosilicates, and others. The amount of metal relative to the amount of silica in the formulation or end product can be from about 0.1 mol % to 99.9 mol %, about 1 mol % or greater, about 10 mol % or greater, and about 20 mole percent or greater. The aforementioned use of metals with precursors of the present invention can be used to control and provide a predetermined stoichiometry. Title and Example
