本揭示內容之進一步的可應用領域將從實施方式、發明申請專利範圍及圖式中變得明顯。詳細說明及具體示例係意圖為僅供說明的目的,而非意欲限制本揭示內容的範圍。The further applicable fields of the present disclosure will become apparent from the embodiments, the scope of the invention patent application, and the drawings. The detailed description and specific examples are intended for illustrative purposes only, and are not intended to limit the scope of the present disclosure.

基板處理系統中的基板支座可包含邊緣環。邊緣環的上表面可在基板支座的上表面上方延伸,使基板支座的上表面(及在一些示例中,配置在基板支座上之基板的上表面)相對於邊緣環內凹。此凹部可被稱為袋部。邊緣環上表面與基板上表面之間的距離可稱為「袋部深度」。通常,袋部深度根據邊緣環相對於基板上表面的高度係固定的。The substrate support in the substrate processing system may include an edge ring. The upper surface of the edge ring may extend above the upper surface of the substrate support such that the upper surface of the substrate support (and in some examples, the upper surface of the substrate disposed on the substrate support) is concave with respect to the edge ring. This recess can be referred to as a pocket. The distance between the upper surface of the edge ring and the upper surface of the substrate can be referred to as the "pocket depth". Generally, the depth of the pocket is fixed according to the height of the edge ring relative to the upper surface of the substrate.

蝕刻處理的一些實施態樣可能由於基板處理系統、基板、氣體混合物等的特性而變化。舉例而言,流動模式及因此蝕刻速率和蝕刻均勻性可根據邊緣環的袋部深度、邊緣環幾何形狀(即形狀)、以及包含但不限於氣流速率、氣體種類、注射角度、注射位置等的其他變量而變化。因此,變化邊緣環的構造(例如包含邊緣環高度及/或幾何形狀)可改變整個基板表面的氣體速度分布。Some implementation aspects of the etching process may vary due to the characteristics of the substrate processing system, the substrate, the gas mixture, and the like. For example, the flow pattern and therefore the etching rate and uniformity of etching can be based on the pocket depth of the edge ring, edge ring geometry (ie shape), and including but not limited to gas flow rate, gas type, injection angle, injection position, etc. Other variables vary. Therefore, changing the structure of the edge ring (for example, including the height and/or geometry of the edge ring) can change the gas velocity distribution on the entire substrate surface.

一些基板處理系統可實施可運動的(例如可調節的)邊緣環及/或可替換的邊緣環。在一示例中,可運動的邊緣環之高度可在處理期間調整以控制蝕刻均勻性。邊緣環可耦接至致動器,該致動器係配置成響應控制器、使用者介面等而升高及降低邊緣環。在一示例中,基板處理系統的控制器根據所執行的特定配方及相關的氣體注射參數在處理期間、處理步驟之間等控制邊緣環的高度。此外,邊緣環及其他元件可包含隨時間磨損/腐蝕的耗材。因此,可調整邊緣環的高度以補償腐蝕。在其他示例中,邊緣環可為可移除的及可替換的(以例如替換腐蝕或損壞的邊緣環、以使用具有不同幾何形狀的邊緣環替換邊緣環等)。實施可運動的及可替換的邊緣環之基板處理系統的示例可在於2015年5月6日申請的美國專利申請案第14/705,430號中找到,其全部內容於此藉由參照納入本案揭示內容。Some substrate processing systems may implement movable (eg, adjustable) edge rings and/or replaceable edge rings. In one example, the height of the movable edge ring can be adjusted during processing to control etching uniformity. The edge ring can be coupled to an actuator that is configured to raise and lower the edge ring in response to a controller, a user interface, and the like. In an example, the controller of the substrate processing system controls the height of the edge ring during processing, between processing steps, etc. according to the specific recipe executed and related gas injection parameters. In addition, the edge ring and other components may include consumables that wear/corrode over time. Therefore, the height of the edge ring can be adjusted to compensate for corrosion. In other examples, the edge ring may be removable and replaceable (for example, to replace a corroded or damaged edge ring, to replace the edge ring with an edge ring with a different geometry, etc.). An example of a substrate processing system implementing a movable and replaceable edge ring can be found in U.S. Patent Application No. 14/705,430 filed on May 6, 2015, the entire content of which is hereby incorporated by reference into the disclosure of this case .

The substrate support 200 may include a base or a base having an inner part (for example, corresponding to an ESC) 208 and an outer part 212. In an example, the outer portion 212 may be independent of the inner portion 208 and movable relative to the inner portion 208. For example, the outer portion 212 may include a bottom ring 216 and a top edge ring 220. The substrate 204 is disposed on the inner portion 208 (for example, on the ceramic layer 224) for processing. The controller 228 communicates with one or more actuators 232 to selectively raise and lower the edge ring 220. For example, the edge ring 220 may be raised and/or lowered during processing to adjust the depth of the pocket of the holder 200. In another example, the edge ring 220 can be raised to facilitate the removal and replacement of the edge ring 220.

僅作為示例,邊緣環220在圖2A中係顯示位在完全降低的位置,而在圖2B中則位在完全升高的位置。如圖所示,致動器232對應於配置成在垂直方向上選擇性地延伸及收回銷236的銷致動器。其他適合類型的致動器可在其他示例中使用。僅作為示例,邊緣環220對應於陶瓷或石英邊緣環,然而可使用其他適合的材料(例如矽碳化物、氧化釔等)。在圖2A中,控制器228與致動器232通訊以藉由銷236直接升高及降低邊緣環220。在一些示例中,內部部分208可相對於外部部分212運動。For example only, the edge ring 220 is shown in a fully lowered position in FIG. 2A, and in a fully raised position in FIG. 2B. As shown, the actuator 232 corresponds to a pin actuator configured to selectively extend and retract the pin 236 in the vertical direction. Other suitable types of actuators can be used in other examples. For example only, the edge ring 220 corresponds to a ceramic or quartz edge ring, but other suitable materials (such as silicon carbide, yttrium oxide, etc.) may be used. In FIG. 2A, the controller 228 communicates with the actuator 232 to directly raise and lower the edge ring 220 via the pin 236. In some examples, the inner portion 208 can move relative to the outer portion 212.

示例基板支座300的特徵係更詳細地顯示於圖3A及3B。基板支座300包含絕緣體環或板304及配置在絕緣體板304上的底板(例如ESC的底板)308。底板308支撐陶瓷層312,該陶瓷層312係配置成支撐配置在其上的基板316以供處理。在圖3A中,陶瓷層312具有非階梯式的配置。在圖3B中,陶瓷層312具有階梯式的配置。基板支座300包含支撐上(「頂部」)邊緣環324的底部環320。一或更多貫孔或導引通道328可穿過絕緣體板304、底部環320、及/或底板308而形成,以容納配置成選擇性地升高及降低邊緣環324之個別升降銷332。舉例而言,導引通道328作為升降銷332之個別者的銷對準孔。如圖3B所示,基板支座300可進一步包含配置在底部環320與邊緣環324之間的中間環336。在階梯式的配置中,中間環336與陶瓷層312重疊且係配置成支撐基板316的外邊緣。The features of an example substrate support 300 are shown in more detail in FIGS. 3A and 3B. The substrate support 300 includes an insulator ring or plate 304 and a bottom plate (such as a bottom plate of an ESC) 308 disposed on the insulator plate 304. The bottom plate 308 supports a ceramic layer 312 configured to support the substrate 316 disposed thereon for processing. In FIG. 3A, the ceramic layer 312 has a non-stepped configuration. In FIG. 3B, the ceramic layer 312 has a stepped configuration. The substrate support 300 includes a bottom ring 320 that supports an upper ("top") edge ring 324. One or more through holes or guide channels 328 may be formed through the insulator plate 304, the bottom ring 320, and/or the bottom plate 308 to accommodate individual lift pins 332 configured to selectively raise and lower the edge ring 324. For example, the guide channel 328 serves as a pin alignment hole of each of the lifting pins 332. As shown in FIG. 3B, the substrate support 300 may further include an intermediate ring 336 disposed between the bottom ring 320 and the edge ring 324. In the stepped configuration, the intermediate ring 336 overlaps the ceramic layer 312 and is configured to support the outer edge of the substrate 316.

升降銷332可包含抗腐蝕材料(例如藍寶石)。升降銷332的外表面可平滑地拋光以減少升降銷332與底部環320的結構特徵之間的摩擦而促進運動。在一些示例中,一或更多陶瓷套筒340可配置在升降銷332周圍的導引通道328中。升降銷332的每一者可包含圓化的上端344,以使上端344與邊緣環324之間的接觸面積最小化。光滑的外表面、圓化的上端344、導引通道328、及/或陶瓷套筒340促進邊緣環324的升高及降低,且同時防止升降銷332在運動期間的沾附。The lift pin 332 may include a corrosion-resistant material (for example, sapphire). The outer surface of the lifting pin 332 can be smoothly polished to reduce the friction between the lifting pin 332 and the structural features of the bottom ring 320 to promote movement. In some examples, one or more ceramic sleeves 340 may be disposed in the guide channel 328 around the lift pin 332. Each of the lift pins 332 may include a rounded upper end 344 to minimize the contact area between the upper end 344 and the edge ring 324. The smooth outer surface, the rounded upper end 344, the guide channel 328, and/or the ceramic sleeve 340 promote the raising and lowering of the edge ring 324, and at the same time prevent the lift pin 332 from sticking during movement.

如圖3A所示,底部環320包含導引特徵部348。在圖3B中,中間環336包含導引特徵部348。舉例而言,導引特徵部348對應於自底部環320/中間環336向上延伸之凸起的環形邊緣352。在圖3A中,導引通道328及升降銷332延伸穿過導引特徵部348以與邊緣環324接合。相反地,在圖3B中,導引通道328及升降銷332延伸穿過底部環320以與邊緣環324接合而不穿過中間環336。As shown in FIG. 3A, the bottom ring 320 includes a guide feature 348. In FIG. 3B, the intermediate ring 336 includes a guide feature 348. For example, the guide feature 348 corresponds to a raised annular edge 352 extending upward from the bottom ring 320/middle ring 336. In FIG. 3A, the guide channel 328 and the lift pin 332 extend through the guide feature 348 to engage with the edge ring 324. Conversely, in FIG. 3B, the guide channel 328 and the lift pin 332 extend through the bottom ring 320 to engage with the edge ring 324 without passing through the middle ring 336.

邊緣環324包含配置成容納導引特徵部348的環形底部凹槽356。舉例而言,邊緣環324的輪廓(即,橫剖面)形狀可大致對應於配置成容納導引特徵部348的「U」形形狀,然而可使用其他合適的形狀。此外,雖然邊緣環324的上表面顯示為大致水平(即,平行於基板支座300的上表面),但在其他示例中,邊緣環324的上表面可具有不同的輪廓。舉例而言,邊緣環324的上表面可為傾斜的或斜向的、圓化的等。在一些示例中,邊緣環324的上表面係傾斜的,使得邊緣環324內直徑處的厚度大於邊緣環324外直徑處的厚度,以補償在內直徑處的腐蝕。The edge ring 324 includes an annular bottom groove 356 configured to receive the guide feature 348. For example, the contour (ie, cross-sectional) shape of the edge ring 324 may generally correspond to the "U" shape configured to accommodate the guide feature 348, although other suitable shapes may be used. In addition, although the upper surface of the edge ring 324 is shown to be substantially horizontal (ie, parallel to the upper surface of the substrate support 300), in other examples, the upper surface of the edge ring 324 may have a different profile. For example, the upper surface of the edge ring 324 may be inclined, oblique, rounded, or the like. In some examples, the upper surface of the edge ring 324 is inclined so that the thickness at the inner diameter of the edge ring 324 is greater than the thickness at the outer diameter of the edge ring 324 to compensate for corrosion at the inner diameter.

因此,邊緣環324的底部表面係配置成與圖3A中底部環320的上表面、或圖3B中底部環320及中間環336的個別表面互補。此外,邊緣環324與底部環320/中間環336之間的界面360係錯綜複雜的。換句話說,邊緣環324的下表面及相應的界面360包含多個方向變化(例如:90度的方向變化、向上及向下的階梯、交替的水平及垂直正交路徑等),而不是在邊緣環324與底部環320/中間環336之間提供通往基板支座300之內部結構的直接(例如直視線)路徑。通常,電漿及製程材料洩漏的可能性在包含多個界面環(例如頂部邊緣環324及中間環336和底部環320的其中一或更多者)的基板支座內可能增加。當可運動的邊緣環324在處理期間升高時此可能性可能進一步增加。因此,界面360(且特別是邊緣環324的輪廓)係配置成防止製程材料、電漿等到達基板支座300的內部結構。Therefore, the bottom surface of the edge ring 324 is configured to be complementary to the upper surface of the bottom ring 320 in FIG. 3A, or the individual surfaces of the bottom ring 320 and the middle ring 336 in FIG. 3B. In addition, the interface 360 between the edge ring 324 and the bottom ring 320/middle ring 336 is intricate. In other words, the lower surface of the edge ring 324 and the corresponding interface 360 include multiple directional changes (for example: 90-degree directional changes, upward and downward steps, alternating horizontal and vertical orthogonal paths, etc.) instead of The edge ring 324 and the bottom ring 320/middle ring 336 provide a direct (for example, direct line of sight) path to the internal structure of the substrate support 300. Generally, the possibility of plasma and process material leakage may increase in a substrate support including multiple interface rings (for example, one or more of the top edge ring 324 and the middle ring 336 and the bottom ring 320). This possibility may further increase when the movable edge ring 324 is raised during processing. Therefore, the interface 360 (and particularly the contour of the edge ring 324) is configured to prevent process materials, plasma, etc. from reaching the internal structure of the substrate support 300.

舉例而言,如圖3A所示,界面360包含五個方向變化以限制到達導引通道328和升降銷332、陶瓷層312、基板316之背面和邊緣等的通路。相反地,如圖3B所示,界面360包含在第一路徑364中的七個方向變化及在第二路徑368中的五個方向變化,以限制到達導引通道328和升降銷332、陶瓷層312、基板316的背面和邊緣、接合層372、密封件376等的通路。因此,界面360降低影響基板支座300之內部結構的電漿洩漏及點燃、腐蝕等的可能性。For example, as shown in FIG. 3A, the interface 360 includes five direction changes to restrict access to the guide channel 328 and the lifting pins 332, the ceramic layer 312, the back surface and the edge of the substrate 316, and so on. On the contrary, as shown in FIG. 3B, the interface 360 includes seven directional changes in the first path 364 and five directional changes in the second path 368 to restrict access to the guide channel 328 and the lift pins 332, ceramic layer 312, the back surface and edge of the substrate 316, the bonding layer 372, the sealing member 376, and the like. Therefore, the interface 360 reduces the possibility of plasma leakage, ignition, corrosion, etc. affecting the internal structure of the substrate support 300.

邊緣環324(及底部環320、中間環336等的界面表面)之輪廓(即橫剖面)形狀係設計成便於製造及降低製造成本。舉例而言,凹槽356的壁380、384及導引特徵部348可為實質垂直的(例如與拋物線、梯形、三角形等相比),以便於製造且同時防止電漿及製程材料洩漏。僅作為示例,實質垂直可定義為垂直於邊緣環324的上及/或下表面、在邊緣環324的上及/或下表面的法線1°之內、平行於邊緣環324的運動方向等。此外,垂直的壁380、384在邊緣環324的運動期間保持邊緣環324相對於導引特徵部348的對準。相反地,當凹槽356及導引特徵部348的個別輪廓係拋物線、梯形、三角形等時,邊緣環324的向上運動導致壁380與壁384之間的顯著分離。The contour (ie, cross section) shape of the edge ring 324 (and the interface surface of the bottom ring 320, the middle ring 336, etc.) is designed to facilitate manufacturing and reduce manufacturing costs. For example, the walls 380, 384 of the groove 356 and the guiding feature 348 may be substantially vertical (for example, compared to a parabola, trapezoid, triangle, etc.) to facilitate manufacturing and at the same time prevent leakage of plasma and process materials. For example only, substantially perpendicular may be defined as being perpendicular to the upper and/or lower surface of the edge ring 324, within 1° of the normal of the upper and/or lower surface of the edge ring 324, parallel to the direction of movement of the edge ring 324, etc. . In addition, the vertical walls 380, 384 maintain the alignment of the edge ring 324 with respect to the guide feature 348 during the movement of the edge ring 324. Conversely, when the individual contours of the groove 356 and the guide feature 348 are parabolic, trapezoidal, triangular, etc., the upward movement of the edge ring 324 causes a significant separation between the wall 380 and the wall 384.

界面360內(且特別是在凹槽356內)之邊緣環324、底部環320、及中間環336的表面係相對平滑且連續的,以在邊緣環324的運動期間使邊緣環324與導引特徵部348之間的摩擦最小化。舉例而言,界面360內之邊緣環324、底部環320、及中間環336的個別表面可能經歷額外的拋光以實現期望的表面光滑度。在其他示例中,界面360內之邊緣環324、底部環320、及中間環336的表面可塗佈進一步減少摩擦的材料。在又其他示例中,界面360內(且特別是邊緣環324)之邊緣環324、底部環320、及中間環336的表面可不具有螺絲孔及/或類似的組件特徵部。以此方式,可使由於表面間的接觸(例如在邊緣環324的運動期間)而產生的粒子減至最少。The surfaces of the edge ring 324, the bottom ring 320, and the middle ring 336 in the interface 360 (and particularly in the groove 356) are relatively smooth and continuous, so that the edge ring 324 and the guide ring 324 are connected during the movement of the edge ring 324. The friction between the features 348 is minimized. For example, the individual surfaces of the edge ring 324, the bottom ring 320, and the middle ring 336 within the interface 360 may undergo additional polishing to achieve the desired surface smoothness. In other examples, the surfaces of the edge ring 324, the bottom ring 320, and the middle ring 336 in the interface 360 may be coated with a material that further reduces friction. In still other examples, the surfaces of the edge ring 324, the bottom ring 320, and the middle ring 336 within the interface 360 (and particularly the edge ring 324) may not have screw holes and/or similar component features. In this way, the generation of particles due to contact between the surfaces (for example, during the movement of the edge ring 324) can be minimized.

當邊緣環324係如上所述在處理期間升高以用於調節時,如圖2A及2B中描述的控制器228係配置成根據導引特徵部348的高度H限制邊緣環324的可調節範圍。舉例而言,可調節範圍可限制為小於導引特徵部348的高度H。舉例而言,若導引特徵部348具有大約0.24”(例如:0.22”-0.26”)的高度H,則邊緣環324的可調節範圍可為0.25”。換句話說,邊緣環324可在不從邊緣環324中的凹槽356完全移除導引特徵部348的情況下自完全降低的位置(例如:0.0”)升高至完全升高的位置(例如:0.25”)。因此,即使在完全升高的位置,邊緣環324仍與導引特徵部348的至少一部分重疊。以此方式限制邊緣環324的範圍保持如上所述之錯綜複雜的界面360,且防止邊緣環324的側向失準。凹槽356的深度可大約等於導引特徵部348的高度H(例如在5%內)。凹槽356的深度可為邊緣環之厚度的至少50%。僅作為示例,圖3A之邊緣環324的可調節範圍係0.15”至0.25”,而圖3B之邊緣環324的可調節範圍係0.05”至0.15”。舉例而言,邊緣環324的厚度(即,高度)可在大約0.50”(例如:0.45”至0.55”)與大約0.6”(例如:0.58”至0.620”)之間,且凹槽356的深度可為大約0.30”(例如:0.29”至0.31”)。When the edge ring 324 is raised for adjustment during processing as described above, the controller 228 as described in FIGS. 2A and 2B is configured to limit the adjustable range of the edge ring 324 according to the height H of the guide feature 348 . For example, the adjustable range may be limited to less than the height H of the guide feature 348. For example, if the guiding feature 348 has a height H of approximately 0.24" (for example: 0.22"-0.26"), the adjustable range of the edge ring 324 may be 0.25". In other words, the edge ring 324 can be raised from a fully lowered position (for example: 0.0") to a fully raised position ( For example: 0.25"). Therefore, even in the fully elevated position, the edge ring 324 still overlaps with at least a portion of the guide feature 348. Limiting the range of the edge ring 324 in this way maintains the intricate interface 360 as described above, and prevents lateral misalignment of the edge ring 324. The depth of the groove 356 may be approximately equal to the height H of the guide feature 348 (for example, within 5%). The depth of the groove 356 may be at least 50% of the thickness of the edge ring. For example only, the adjustable range of the edge ring 324 in FIG. 3A is 0.15" to 0.25", and the adjustable range of the edge ring 324 in FIG. 3B is 0.05" to 0.15". For example, the thickness (ie, the height) of the edge ring 324 may be between about 0.50" (for example: 0.45" to 0.55") and about 0.6" (for example: 0.58" to 0.620"), and the depth of the groove 356 It can be about 0.30" (for example: 0.29" to 0.31").

舉例而言,如本文所使用之邊緣環324的「厚度」可意指邊緣環324內直徑處之邊緣環324的厚度(例如在內壁388處之邊緣環324的厚度/高度)。在一些示例中,邊緣環324的厚度在邊緣環324的整個上表面可能不是均勻的(例如邊緣環324的上表面如上所述可為傾斜的,使得內壁388處的厚度大於邊緣環324外直徑處的厚度)。然而,由於曝露於電漿引起的腐蝕可能相對於邊緣環324的外直徑在內壁388處增加,所以邊緣環324可形成為使得內壁388至少具有預定的厚度以補償在內壁388處增加的腐蝕。僅作為示例,內壁388係實質垂直的以避免在邊緣環324的運動期間接觸基板316。For example, the “thickness” of the edge ring 324 as used herein may mean the thickness of the edge ring 324 at the inner diameter of the edge ring 324 (eg, the thickness/height of the edge ring 324 at the inner wall 388). In some examples, the thickness of the edge ring 324 may not be uniform across the upper surface of the edge ring 324 (for example, the upper surface of the edge ring 324 may be inclined as described above, so that the thickness at the inner wall 388 is greater than the outer surface of the edge ring 324. Thickness at the diameter). However, since corrosion caused by exposure to plasma may increase at the inner wall 388 relative to the outer diameter of the edge ring 324, the edge ring 324 may be formed such that the inner wall 388 has at least a predetermined thickness to compensate for the increase at the inner wall 388 Corrosion. For example only, the inner wall 388 is substantially vertical to avoid contacting the substrate 316 during the movement of the edge ring 324.

現參照圖4A、4B、及4C,更詳細地顯示另一示例基板支座400。基板支座400包含絕緣體環或板404及配置在絕緣體板404上的底板408。底板408支撐陶瓷層412,該陶瓷層412係配置成支撐配置在其上的基板416以供處理。在圖4A中,陶瓷層412具有非階梯式的配置。在圖4B及4C中,陶瓷層412具有階梯式的配置。基板支座400包含支撐上邊緣環424的底部環420。在階梯式的配置中,邊緣環424與陶瓷層412重疊。一或更多貫孔或導引通道428可穿過絕緣體板404、底部環420、及/或底板408而形成,以容納配置成選擇性地升高及降低邊緣環424之個別升降銷432。舉例而言,導引通道428作為升降銷432之個別者的銷對準孔。4A, 4B, and 4C, another example substrate support 400 is shown in more detail. The substrate support 400 includes an insulator ring or plate 404 and a bottom plate 408 disposed on the insulator plate 404. The bottom plate 408 supports a ceramic layer 412 configured to support a substrate 416 disposed thereon for processing. In FIG. 4A, the ceramic layer 412 has a non-stepped configuration. In FIGS. 4B and 4C, the ceramic layer 412 has a stepped configuration. The substrate support 400 includes a bottom ring 420 supporting an upper edge ring 424. In the stepped configuration, the edge ring 424 overlaps the ceramic layer 412. One or more through holes or guide channels 428 may be formed through the insulator plate 404, the bottom ring 420, and/or the bottom plate 408 to accommodate individual lift pins 432 configured to selectively raise and lower the edge ring 424. For example, the guide channel 428 serves as a pin alignment hole of each of the lifting pins 432.

在圖4A、4B、及4C的示例中,邊緣環424係配置成支撐配置在陶瓷層412上之基板416的外邊緣。舉例而言,邊緣環424的內直徑包含配置成支撐基板416之外邊緣的台階434。因此,邊緣環424可升高及降低以促進邊緣環424的移除及替換,但在處理期間可能不升高及降低(即,邊緣環424係非可調節的)。舉例而言,可使用升降銷432升高邊緣環424以進行移除及替換(例如使用機器人170)。In the examples of FIGS. 4A, 4B, and 4C, the edge ring 424 is configured to support the outer edge of the substrate 416 disposed on the ceramic layer 412. For example, the inner diameter of the edge ring 424 includes a step 434 configured to support the outer edge of the substrate 416. Therefore, the edge ring 424 can be raised and lowered to facilitate removal and replacement of the edge ring 424, but may not be raised and lowered during processing (ie, the edge ring 424 is non-adjustable). For example, the lifting pin 432 may be used to raise the edge ring 424 for removal and replacement (eg, using the robot 170).

在一示例中,邊緣環424的下部內角隅436可加以倒角以促進基板支座400上之邊緣環424的對準(即置中)。相反地,陶瓷層412的上部外角隅444及/或下部內角隅448可對於角隅436互補性地倒角。因此,當邊緣環424係降低在基板支座400上時,倒角的角隅436與倒角的角隅444/448互動以使邊緣環424在基板支座400上自行置中。In one example, the lower inner corner 436 of the edge ring 424 may be chamfered to facilitate the alignment (ie, centering) of the edge ring 424 on the substrate support 400. Conversely, the upper outer corner 444 and/or the lower inner corner 448 of the ceramic layer 412 may be chamfered complementary to the corner 436. Therefore, when the edge ring 424 is lowered on the substrate support 400, the chamfered corner 436 interacts with the chamfered corners 444/448 so that the edge ring 424 is centered on the substrate support 400 by itself.

邊緣環424的上部外角隅456可加以倒角以促進邊緣環424自處理腔室102的移除。舉例而言,由於基板支座400係配置成用於邊緣環424的原位移除(即,不完全打開及排氣處理腔室102的情況下),所以邊緣環424係配置成經由氣室移除。通常,氣室的尺寸係選擇成容納預定尺寸(例如300 mm)的基板。然而,邊緣環424具有明顯大於基板416的直徑且典型的邊緣環424可能不適合通過氣室。因此,減少邊緣環424的直徑(例如與圖3A及3B顯示的邊緣環324相比)。舉例而言,邊緣環324的外直徑係類似於底部環320的外直徑。相反地,邊緣環424的外直徑明顯小於底部環420的外直徑。僅作為示例,邊緣環424的外直徑小於或等於大約13”(例如:12.5”至13”)。使外角隅456加以倒角進一步促進邊緣環424通過氣室的轉移。The upper outer corner 456 of the edge ring 424 can be chamfered to facilitate the removal of the edge ring 424 from the processing chamber 102. For example, since the substrate holder 400 is configured for in-situ removal of the edge ring 424 (that is, when the processing chamber 102 is not fully opened and exhausted), the edge ring 424 is configured to pass through the air chamber Remove. Generally, the size of the air chamber is selected to accommodate a substrate of a predetermined size (eg, 300 mm). However, the edge ring 424 has a diameter significantly larger than the substrate 416 and the typical edge ring 424 may not be suitable for passing through the air chamber. Therefore, the diameter of the edge ring 424 is reduced (for example, compared to the edge ring 324 shown in FIGS. 3A and 3B). For example, the outer diameter of the edge ring 324 is similar to the outer diameter of the bottom ring 320. Conversely, the outer diameter of the edge ring 424 is significantly smaller than the outer diameter of the bottom ring 420. For example only, the outer diameter of the edge ring 424 is less than or equal to about 13" (for example: 12.5" to 13"). Chamfering the outer corner 456 further facilitates the transfer of the edge ring 424 through the air chamber.

僅作為示例,外角隅的倒角可具有0.050”至0.070”的高度、0.030”至0.050”的寬度、及25-35°的角度。在一些示例中,下部角隅436的倒角可具有大約0.025”(例如:0.015”至0.040”)的高度、大約0.015”(例如:0.005”至0.030”)的寬度、及大約60°(50-70°)的角度。僅作為示例,邊緣環424的厚度(即高度)係大約但不大於0.275”(例如:0.25”至0.30”)。舉例而言,邊緣環424的厚度可能不超過處理腔室102之氣室的高度,以允許邊緣環424的移除。僅作為示例,如本文使用之邊緣環424的「厚度」可如以上關於圖3A及3B所述意指在邊緣環424內直徑處之邊緣環424的厚度(例如在內壁458處之邊緣環424的厚度/高度)。For example only, the chamfer of the outer corner may have a height of 0.050" to 0.070", a width of 0.030" to 0.050", and an angle of 25-35°. In some examples, the chamfer of the lower corner 436 may have a height of approximately 0.025" (e.g., 0.015" to 0.040"), a width of approximately 0.015" (e.g., 0.005" to 0.030"), and a width of approximately 60° (50 -70°) angle. For example only, the thickness (ie height) of the edge ring 424 is approximately but not greater than 0.275" (for example: 0.25" to 0.30"). For example, the thickness of the edge ring 424 may not exceed the thickness of the gas chamber of the processing chamber 102 Height to allow removal of the edge ring 424. For example only, the "thickness" of the edge ring 424 as used herein may mean the thickness of the edge ring 424 at the inner diameter of the edge ring 424 as described above with respect to FIGS. 3A and 3B Thickness (for example, the thickness/height of the edge ring 424 at the inner wall 458).

如圖4C所示,底部環420包含導引特徵部460。舉例而言,導引特徵部460對應於自底部環420向上延伸之凸起的環形邊緣464。導引通道428及升降銷432延伸穿過底部環420以與邊緣環424接合。邊緣環424包含配置成容納導引特徵部460的環形底部凹槽468。舉例而言,邊緣環424的輪廓可大致對應於配置成容納導引特徵部460的「U」形形狀。As shown in FIG. 4C, the bottom ring 420 includes a guide feature 460. For example, the guiding feature 460 corresponds to a raised annular edge 464 extending upward from the bottom ring 420. The guide channel 428 and the lifting pin 432 extend through the bottom ring 420 to be engaged with the edge ring 424. The edge ring 424 includes an annular bottom groove 468 configured to receive the guide feature 460. For example, the contour of the edge ring 424 may generally correspond to the “U” shape configured to accommodate the guide feature 460.

因此,類似於圖3A及3B的示例,圖4C中之邊緣環424的底部表面係配置成與底部環420及陶瓷層412的個別上表面互補以形成錯綜複雜的界面472。換句話說,界面472包含多個方向變化(例如90度的方向變化),而不是在邊緣環424與底部環420之間提供通往基板支座400之內部結構的直接路徑。在一些示例中,界面472內之導引特徵部460、邊緣環424、底部環420、及/或陶瓷層412的部分可加以倒角以促進基板支座400上之邊緣環424的對準(即置中)。舉例而言,邊緣環424之內直徑的下部內角隅476及相應之陶瓷層412的下部內角隅480及/或上部外角隅484係加以倒角。在其他示例中,凹槽468內之導引特徵部460的機械對準使邊緣環424置中。在一些示例中,下部角隅476的倒角可具有大約0.025”(例如:0.015”至0.040”)的高度、大約0.015”(例如:0.005”至0.030”)的寬度、及大約60°(例如:50-60°)的角度。Therefore, similar to the example of FIGS. 3A and 3B, the bottom surface of the edge ring 424 in FIG. 4C is configured to complement the respective upper surfaces of the bottom ring 420 and the ceramic layer 412 to form an intricate interface 472. In other words, the interface 472 includes multiple directional changes (for example, a 90-degree directional change), instead of providing a direct path between the edge ring 424 and the bottom ring 420 to the internal structure of the substrate support 400. In some examples, portions of the guide features 460, the edge ring 424, the bottom ring 420, and/or the ceramic layer 412 within the interface 472 may be chamfered to facilitate the alignment of the edge ring 424 on the substrate support 400 ( That is centered). For example, the lower inner corner 476 of the inner diameter of the edge ring 424 and the corresponding lower inner corner 480 and/or upper outer corner 484 of the ceramic layer 412 are chamfered. In other examples, the mechanical alignment of the guide feature 460 in the groove 468 centers the edge ring 424. In some examples, the chamfer of the lower corner 476 may have a height of approximately 0.025" (e.g., 0.015" to 0.040"), a width of approximately 0.015" (e.g., 0.005" to 0.030"), and a width of approximately 60° (e.g., : 50-60°) angle.

現參照圖5A及5B,更詳細地顯示另一示例基板支座500。基板支座500包含絕緣體環或板504及配置在絕緣體板504上的底板508。底板508支撐陶瓷層512,該陶瓷層512係配置成支撐配置在其上的基板516以供處理。在圖5A中,陶瓷層512具有非階梯式的配置。在圖5B中,陶瓷層512具有階梯式的配置。基板支座500包含支撐上邊緣環524(如圖5A所示)或上邊緣環526(如圖5B所示)的底部環520。一或更多貫孔或導引通道528可穿過絕緣體板504、底部環520、及/或底板508而形成,以容納配置成選擇性地升高及降低邊緣環524/526之個別升降銷532。舉例而言,導引通道528作為升降銷532之個別者的銷對準孔。如圖5B所示,基板支座500可進一步包含配置在底部環520與邊緣環526之間的中間環536。在階梯式的配置中,中間環536與陶瓷層512重疊且係配置成支撐基板516的外邊緣。Referring now to FIGS. 5A and 5B, another example substrate support 500 is shown in more detail. The substrate support 500 includes an insulator ring or plate 504 and a bottom plate 508 disposed on the insulator plate 504. The bottom plate 508 supports a ceramic layer 512 configured to support a substrate 516 disposed thereon for processing. In FIG. 5A, the ceramic layer 512 has a non-stepped configuration. In FIG. 5B, the ceramic layer 512 has a stepped configuration. The substrate support 500 includes a bottom ring 520 that supports an upper edge ring 524 (as shown in FIG. 5A) or an upper edge ring 526 (as shown in FIG. 5B). One or more through holes or guide channels 528 may be formed through the insulator plate 504, the bottom ring 520, and/or the bottom plate 508 to accommodate individual lift pins configured to selectively raise and lower the edge ring 524/526 532. For example, the guide channel 528 serves as a pin alignment hole of each of the lifting pins 532. As shown in FIG. 5B, the substrate support 500 may further include an intermediate ring 536 disposed between the bottom ring 520 and the edge ring 526. In the stepped configuration, the intermediate ring 536 overlaps the ceramic layer 512 and is configured to support the outer edge of the substrate 516.

圖5A及5B的示例結合圖3A及3B之可調節的邊緣環324及圖4A、4B、及4C之可移除的/可替換的邊緣環之特徵。舉例而言,即使在圖5B之階梯式的配置中,邊緣環526也不在基板516下方延伸及支撐基板516。因此,邊緣環524/526可在處理期間升高及降低。僅作為示例,圖5A之邊緣環524的可調節範圍係0.05”至0.15”,而圖5B之邊緣環526的可調節範圍係0.02”至0.05”。此外,邊緣環524/526的外直徑係如關於圖4A、4B、及4C所述般減少,以促進邊緣環524/526通過氣室的轉移。因此,邊緣環524/526如上所述可原位移除及替換。The example of FIGS. 5A and 5B combines the features of the adjustable edge ring 324 of FIGS. 3A and 3B and the removable/replaceable edge ring of FIGS. 4A, 4B, and 4C. For example, even in the stepped configuration of FIG. 5B, the edge ring 526 does not extend under the substrate 516 and support the substrate 516. Therefore, the edge ring 524/526 can be raised and lowered during processing. For example only, the adjustable range of the edge ring 524 in FIG. 5A is 0.05" to 0.15", and the adjustable range of the edge ring 526 in FIG. 5B is 0.02" to 0.05". In addition, the outer diameter of the edge ring 524/526 is reduced as described with respect to FIGS. 4A, 4B, and 4C to promote the transfer of the edge ring 524/526 through the air chamber. Therefore, the edge ring 524/526 can be removed and replaced in situ as described above.

如圖5A所示,底部環520包含導引特徵部540。在圖5B中,中間環536包含導引特徵部540。舉例而言,導引特徵部540對應於自底部環520/中間環536向上延伸之凸起的環形邊緣544。在圖5A及5B之各者中,導引通道528及升降銷532延伸穿過底部環520以與邊緣環524/526接合。舉例而言,邊緣環524/526包含配置成容納導引特徵部540的環形底部凹槽548。舉例而言,邊緣環524/526的輪廓可大致對應於配置成容納導引特徵部540的「U」形形狀。As shown in FIG. 5A, the bottom ring 520 includes a guide feature 540. In FIG. 5B, the intermediate ring 536 includes a guide feature 540. For example, the guiding feature 540 corresponds to a raised annular edge 544 extending upward from the bottom ring 520/middle ring 536. In each of FIGS. 5A and 5B, the guide channel 528 and the lift pin 532 extend through the bottom ring 520 to engage with the edge ring 524/526. For example, the edge ring 524/526 includes an annular bottom groove 548 configured to receive the guide feature 540. For example, the contour of the edge ring 524/526 may generally correspond to the "U" shape configured to accommodate the guide feature 540.

因此,類似於圖3A、3B及4C的示例,邊緣環524/526的底部表面係配置成與底部環520及中間環536的個別上表面互補以形成錯綜複雜的界面552。換句話說,界面552包含多個方向變化(例如90度的方向變化),而不是在邊緣環524/526與底部環520之間提供通往基板支座500之內部結構的直接路徑。在一些示例中,界面552內之導引特徵部540、邊緣環524/526、底部環520、及/或中間環536的部分可加以倒角以促進基板支座500上之邊緣環524/526的對準(即置中)。舉例而言,在圖5A中,邊緣環524的角隅556和558及導引特徵部540的互補角隅560及底部環520的角隅562係加以倒角。相反地,在圖5B中,只有邊緣環526的角隅556及中間環536的角隅560係加以倒角。邊緣環524的上部外角隅564可加以倒角以如上關於圖4A、4B及4C所述促進邊緣環524自處理腔室102的移除。Therefore, similar to the example of FIGS. 3A, 3B, and 4C, the bottom surface of the edge ring 524/526 is configured to complement the respective upper surfaces of the bottom ring 520 and the middle ring 536 to form an intricate interface 552. In other words, the interface 552 includes multiple directional changes (for example, a 90-degree directional change), instead of providing a direct path between the edge ring 524/526 and the bottom ring 520 to the internal structure of the substrate support 500. In some examples, portions of the guide features 540, the edge ring 524/526, the bottom ring 520, and/or the middle ring 536 within the interface 552 may be chamfered to facilitate the edge ring 524/526 on the substrate support 500 Alignment (ie centering). For example, in FIG. 5A, the corners 556 and 558 of the edge ring 524 and the complementary corner 560 of the guide feature 540 and the corner 562 of the bottom ring 520 are chamfered. In contrast, in FIG. 5B, only the corner 556 of the edge ring 526 and the corner 560 of the middle ring 536 are chamfered. The upper outer corner 564 of the edge ring 524 may be chamfered to facilitate the removal of the edge ring 524 from the processing chamber 102 as described above with respect to FIGS. 4A, 4B, and 4C.

僅作為示例,下部角隅556和558的倒角可具有大約0.005”至0.030”的高度和寬度及大約25至35°的角度。舉例而言,邊緣環524/526的厚度(即高度)可為大約但不大於0.25”(例如:0.25”至0.26”),且凹槽548的深度可為0.200”至0.220”。邊緣環524/526的厚度與凹槽548的深度之間的差可不小於0.075”。舉例而言,邊緣環524/526的厚度可不超過處理腔室102之氣室的高度以允許邊緣環524/526的移除。然而,在不超過氣室的高度之情況下,邊緣環524/526的厚度亦可最大化,以使邊緣環524/526的可調性最佳化。換句話說,因為邊緣環524/526隨時間磨損,所以邊緣環524/526可在不需被更換的情況下升高的量與邊緣環524/526的厚度成比例地增加。僅作為示例,如本文使用之邊緣環524/526的「厚度」可如以上關於圖3A、3B、4A、4B及4C所述意指在邊緣環524/526內直徑處之邊緣環524/526的厚度(例如在內壁568處之邊緣環524/5264的厚度/高度)。For example only, the chamfers of the lower corners 556 and 558 may have a height and width of about 0.005" to 0.030" and an angle of about 25 to 35°. For example, the thickness (ie, height) of the edge ring 524/526 can be approximately but not greater than 0.25" (for example: 0.25" to 0.26"), and the depth of the groove 548 can be 0.200" to 0.220". The edge ring 524 The difference between the thickness of /526 and the depth of groove 548 may not be less than 0.075". For example, the thickness of the edge ring 524/526 may not exceed the height of the air chamber of the processing chamber 102 to allow the edge ring 524/526 to be removed. However, if the height of the air chamber is not exceeded, the thickness of the edge ring 524/526 can also be maximized to optimize the adjustability of the edge ring 524/526. In other words, because the edge ring 524/526 wears out over time, the amount that the edge ring 524/526 can rise without being replaced increases in proportion to the thickness of the edge ring 524/526. For example only, the "thickness" of the edge ring 524/526 as used herein may mean the edge ring 524/526 at the inner diameter of the edge ring 524/526 as described above with respect to FIGS. 3A, 3B, 4A, 4B, and 4C (For example, the thickness/height of the edge ring 524/5264 at the inner wall 568).

現參照圖6A及圖6B,示例底部環600(例如對應於底部環320、420或520之其中任一者)可實施同步特徵部(clocking feature)以促進底部環600與絕緣體環604的對準。底部環600包含配置成容納延伸穿過絕緣體環604之個別升降銷612的複數導引通道608。底部環600更包含一或更多同步特徵部,諸如刻槽616。刻槽616係配置成容納互補的結構,諸如自絕緣體環604向上延伸的突出物620。因此,底部環600可安裝成使得刻槽616與突出物620對齊並容納突出物620,以確保導引通道608與升降銷612的個別者對齊。6A and 6B, the example bottom ring 600 (for example, corresponding to any one of the bottom ring 320, 420, or 520) may implement a clocking feature to facilitate the alignment of the bottom ring 600 and the insulator ring 604 . The bottom ring 600 includes a plurality of guide channels 608 configured to receive individual lift pins 612 extending through the insulator ring 604. The bottom ring 600 further includes one or more synchronization features, such as notches 616. The notch 616 is configured to accommodate a complementary structure, such as a protrusion 620 extending upward from the insulator ring 604. Therefore, the bottom ring 600 can be installed such that the notch 616 is aligned with the protrusion 620 and accommodates the protrusion 620 to ensure that the guide channel 608 is aligned with the individual of the lifting pin 612.

現參照圖7A、7B、及7C,基板支座700包含根據本揭示內容的原理設置成以非階梯式的配置支撐頂部可運動的邊緣環之示例底部環704、708、及712。舉例而言,如圖7A所示,底部環704係配置成支撐圖3A的邊緣環324。如圖7B所示,底部環708係配置成支撐圖4A的邊緣環424。如圖7C所示,底部環712係配置成支撐圖5A的邊緣環524。底部環704、708、及712之其中各者的個別上表面係階梯式的。換句話說,該等個別上表面的其中各者具有至少兩不同高度。Referring now to FIGS. 7A, 7B, and 7C, the substrate support 700 includes example bottom rings 704, 708, and 712 configured to support a movable top edge ring in a non-stepped configuration according to the principles of the present disclosure. For example, as shown in FIG. 7A, the bottom ring 704 is configured to support the edge ring 324 of FIG. 3A. As shown in FIG. 7B, the bottom ring 708 is configured to support the edge ring 424 of FIG. 4A. As shown in FIG. 7C, the bottom ring 712 is configured to support the edge ring 524 of FIG. 5A. The individual upper surfaces of each of the bottom rings 704, 708, and 712 are stepped. In other words, each of the individual upper surfaces has at least two different heights.

基板支座700包含絕緣體環或板716及配置在絕緣體板716上的底板(例如ESC的底板)720。底板720支撐陶瓷層724,該陶瓷層724係配置成支撐其上的基板以供處理。一或更多貫孔或導引通道728可穿過絕緣體板716及底部環704、708、712而形成,以容納配置成選擇性地升高及降低個別邊緣環的升降銷732。舉例而言,導引通道728作為升降銷732之個別者的銷對準孔。升降銷732與導引通道728之內表面間的間隙係最小化以減少電漿洩漏。換句話說,導引通道728的直徑係僅比升降銷732的直徑稍大(例如大0.005”-0.010”)。舉例而言,升降銷732可具有0.057”-0.061”的直徑,而導引通道728具有0.063”-0.067”的直徑。在一些示例中,導引通道728包含窄區域734,其具有小於導引通道728之其他部分的直徑以進一步限制電漿洩露。舉例而言,窄區域734可具有比導引通道728之直徑小0.002-0.004”的直徑。類似地,在一些示例中,升降銷732可包含位在導引通道728之窄區域734內的窄區域。The substrate support 700 includes an insulator ring or plate 716 and a bottom plate (such as a bottom plate of an ESC) 720 disposed on the insulator plate 716. The bottom plate 720 supports a ceramic layer 724, which is configured to support the substrate thereon for processing. One or more through holes or guide channels 728 may be formed through the insulator plate 716 and the bottom rings 704, 708, 712 to accommodate lift pins 732 configured to selectively raise and lower individual edge rings. For example, the guide channel 728 serves as a pin alignment hole of each of the lifting pins 732. The gap between the lift pin 732 and the inner surface of the guide channel 728 is minimized to reduce plasma leakage. In other words, the diameter of the guiding channel 728 is only slightly larger than the diameter of the lifting pin 732 (for example, 0.005"-0.010" larger). For example, the lift pin 732 may have a diameter of 0.057"-0.061", and the guide channel 728 may have a diameter of 0.063"-0.067". In some examples, the guide channel 728 includes a narrow area 734 that has a smaller diameter than other parts of the guide channel 728 to further limit plasma leakage. For example, the narrow area 734 may have a diameter 0.002-0.004" smaller than the diameter of the guide channel 728. Similarly, in some examples, the lift pin 732 may include a narrow area 734 within the narrow area 734 of the guide channel 728. area.

如圖7A所示,底部環704包含導引特徵部736。舉例而言,導引特徵部736對應於自底部環704向上延伸之凸起的環形邊緣740。邊緣740及內環形邊緣742定義凹槽744。導引通道728及升降銷732延伸穿過導引特徵部736。底部環704的上表面係配置成與邊緣環324的底部表面互補以如上所述形成包含多個方向變化之錯綜複雜的界面。凹槽744及邊緣740的個別寬度係加以選擇以使凹槽744和邊緣740之個別垂直表面與邊緣環324底部上之互補垂直表面間的間隙最小化。舉例而言,該間隙可為小於0.02”。As shown in FIG. 7A, the bottom ring 704 includes a guide feature 736. For example, the guide feature 736 corresponds to a raised annular edge 740 extending upward from the bottom ring 704. The edge 740 and the inner annular edge 742 define a groove 744. The guide channel 728 and the lift pin 732 extend through the guide feature 736. The upper surface of the bottom ring 704 is configured to be complementary to the bottom surface of the edge ring 324 to form an intricate interface including multiple directional changes as described above. The individual widths of the groove 744 and the edge 740 are selected to minimize the gap between the individual vertical surfaces of the groove 744 and the edge 740 and the complementary vertical surface on the bottom of the edge ring 324. For example, the gap may be less than 0.02".

類似地,如圖7C所示,底部環712包含導引特徵部746。舉例而言,導引特徵部746對應於自底部環712向上延伸之凸起的環形邊緣748。邊緣748及內環形邊緣750定義第一凹槽752,而邊緣748及外環形邊緣754定義第二凹槽756。導引通道728及升降銷732延伸穿過底部環712。底部環712的上表面係配置成與邊緣環524的底部表面互補以如上所述形成包含多個方向變化之錯綜複雜的界面。邊緣748的高度大於內環形邊緣750的高度,以在內環形邊緣750與邊緣環524間的接觸之前促進邊緣748與邊緣環524的接合。Similarly, as shown in FIG. 7C, the bottom ring 712 includes a guide feature 746. For example, the guiding feature 746 corresponds to a raised annular edge 748 extending upward from the bottom ring 712. The edge 748 and the inner annular edge 750 define the first groove 752, and the edge 748 and the outer annular edge 754 define the second groove 756. The guiding channel 728 and the lifting pin 732 extend through the bottom ring 712. The upper surface of the bottom ring 712 is configured to be complementary to the bottom surface of the edge ring 524 to form an intricate interface including multiple directional changes as described above. The height of the edge 748 is greater than the height of the inner annular edge 750 to facilitate the engagement of the edge 748 with the edge ring 524 before the contact between the inner annular edge 750 and the edge ring 524.

在一些示例中,導引特徵部746及/或底部環712的部分可加以倒角以促進基板支座700上之邊緣環524的對準(即置中)。舉例而言,導引特徵部746的角隅760和764及底部環712的角隅768係加以倒角。在一些示例中,角隅760的倒角可具有至少大約0.008”(例如:0.007”至0.011”)的高度和寬度及15-25°的角度。角隅764的倒角可具有至少大約0.01”(例如:0.01”至0.02”)高度和寬度及20-35°的角度。角隅768的倒角可具有至少大約0.010”(例如:0.010”至0.030”)的高度和寬度及20-35°的角度。In some examples, portions of the guide features 746 and/or the bottom ring 712 may be chamfered to facilitate the alignment (ie, centering) of the edge ring 524 on the substrate support 700. For example, the corners 760 and 764 of the guide feature 746 and the corner 768 of the bottom ring 712 are chamfered. In some examples, the chamfer of the corner corner 760 may have a height and width of at least about 0.008" (e.g., 0.007" to 0.011") and an angle of 15-25°. The chamfer of the corner corner 764 may have at least about 0.01" (For example: 0.01" to 0.02") Height and width and angle of 20-35°. The chamfer of the corner 768 may have a height and width of at least about 0.010" (for example: 0.010" to 0.030") and an angle of 20-35°.

底部環704、708及712的內直徑可為至少11.5”(例如在11.5”和11.7”之間)。底部環704、708及712的外直徑可為不大於14”(例如在13.8”和14.1”之間)。在772處之底部環708及712的階梯式內直徑係加以選擇以容納邊緣環424或524的外直徑。舉例而言,邊緣環424或524的外直徑可為大約12.8”(例如:+/-0.10”)。因此,在772處之底部環708及712的內直徑可為至少13.0”。The inner diameter of the bottom rings 704, 708, and 712 may be at least 11.5” (for example, between 11.5” and 11.7”). The outer diameter of the bottom rings 704, 708, and 712 may be no more than 14” (for example, between 13.8” and 14.1” "between). The stepped inner diameter of the bottom ring 708 and 712 at 772 is selected to accommodate the outer diameter of the edge ring 424 or 524. For example, the outer diameter of the edge ring 424 or 524 may be approximately 12.8" (for example: +/-0.10"). Therefore, the inner diameter of the bottom rings 708 and 712 at 772 can be at least 13.0".

現參照圖8A、8B、及8C,基板支座800包含根據本揭示內容的原理設置成以階梯式的配置支撐頂部可運動的邊緣環之示例底部環804、808、及812。舉例而言,如圖8A所示,底部環804係配置成支撐圖3B的邊緣環324。如圖8B所示,底部環808係配置成支撐圖4C的邊緣環424。如圖8C所示,底部環812係配置成支撐圖5B的邊緣環526。底部環804及812可進一步配置成分別支撐圖3B的中間環336及圖5B的中間環536。底部環804、808、及812之其中各者的個別上表面係階梯式的。換句話說,該等個別上表面的其中各者具有至少兩不同高度。Referring now to FIGS. 8A, 8B, and 8C, the substrate support 800 includes example bottom rings 804, 808, and 812 arranged to support a movable top edge ring in a stepped configuration according to the principles of the present disclosure. For example, as shown in FIG. 8A, the bottom ring 804 is configured to support the edge ring 324 of FIG. 3B. As shown in FIG. 8B, the bottom ring 808 is configured to support the edge ring 424 of FIG. 4C. As shown in FIG. 8C, the bottom ring 812 is configured to support the edge ring 526 of FIG. 5B. The bottom rings 804 and 812 may be further configured to support the middle ring 336 of FIG. 3B and the middle ring 536 of FIG. 5B, respectively. The individual upper surfaces of each of the bottom rings 804, 808, and 812 are stepped. In other words, each of the individual upper surfaces has at least two different heights.

基板支座800包含絕緣體環或板816及配置在絕緣體板816上的底板(例如ESC的底板)820。底板820支撐陶瓷層824,該陶瓷層824係配置成支撐其上的基板以供處理。接合層828可配置在底板820與陶瓷層824之間,且密封件832圍繞接合層828。一或更多貫孔或導引通道836可穿過絕緣體板816及底部環804、808、812而形成,以容納配置成選擇性地升高及降低個別邊緣環的升降銷840。舉例而言,導引通道836作為升降銷840之個別者的銷對準孔。升降銷840與導引通道836之內表面間的間隙係最小化以減少電漿洩漏。換句話說,導引通道836的直徑係僅比升降銷840的直徑稍大(例如大0.005”-0.010”)。舉例而言,升降銷840可具有0.1”的直徑,而導引通道836具有0.105”的直徑。在一些示例中,導引通道836包含窄區域842,其具有小於導引通道836之其他部分的直徑以進一步限制電漿洩露。舉例而言,窄區域842可具有比導引通道836之直徑小0.002-0.004”的直徑。在一些示例中,一或更多陶瓷套筒844可配置在圍繞升降銷840的導引通道836內。The substrate support 800 includes an insulator ring or plate 816 and a bottom plate (for example, a bottom plate of an ESC) 820 disposed on the insulator plate 816. The bottom plate 820 supports a ceramic layer 824 that is configured to support the substrate thereon for processing. The bonding layer 828 may be disposed between the bottom plate 820 and the ceramic layer 824, and the sealing member 832 surrounds the bonding layer 828. One or more through holes or guide channels 836 may be formed through the insulator plate 816 and the bottom rings 804, 808, 812 to accommodate lift pins 840 configured to selectively raise and lower individual edge rings. For example, the guide channel 836 serves as a pin alignment hole of each of the lifting pins 840. The gap between the lift pin 840 and the inner surface of the guide channel 836 is minimized to reduce plasma leakage. In other words, the diameter of the guide channel 836 is only slightly larger than the diameter of the lift pin 840 (for example, 0.005"-0.010" larger). For example, the lift pin 840 may have a diameter of 0.1", and the guide channel 836 has a diameter of 0.105". In some examples, the guide channel 836 includes a narrow area 842 that has a smaller diameter than other parts of the guide channel 836 to further limit plasma leakage. For example, the narrow area 842 may have a diameter 0.002-0.004" smaller than the diameter of the guide channel 836. In some examples, one or more ceramic sleeves 844 may be disposed in the guide channel 836 surrounding the lift pin 840 .

如圖8B所示,底部環808包含導引特徵部846。舉例而言,導引特徵部846對應於自底部環808向上延伸之凸起的環形邊緣848。邊緣848及外環形邊緣850定義凹槽852。底部環808的上表面係配置成與邊緣環424的底部表面互補以如上所述形成包含多個方向變化之錯綜複雜的界面。凹槽852及邊緣848的個別寬度係加以選擇以使凹槽852和邊緣848之個別垂直表面與邊緣環424底部上之互補垂直表面間的間隙最小化。舉例而言,該間隙可為小於0.010”。相反地,如圖8A及8C所示,底部環804及812係配置成支撐具有個別之導引特徵部348及540的中間環336及536。因此,底部環804及812的上表面係配置成結合中間環336及536的上表面、與邊緣環324及526的底部表面互補以如上所述形成包含多個方向變化之錯綜複雜的界面。As shown in FIG. 8B, the bottom ring 808 includes guide features 846. For example, the guide feature 846 corresponds to a raised annular edge 848 extending upward from the bottom ring 808. The edge 848 and the outer annular edge 850 define a groove 852. The upper surface of the bottom ring 808 is configured to be complementary to the bottom surface of the edge ring 424 to form an intricate interface including multiple directional changes as described above. The individual widths of the groove 852 and the edge 848 are selected to minimize the gap between the individual vertical surfaces of the groove 852 and the edge 848 and the complementary vertical surface on the bottom of the edge ring 424. For example, the gap can be less than 0.010". Conversely, as shown in Figures 8A and 8C, the bottom rings 804 and 812 are configured to support the intermediate rings 336 and 536 with individual guide features 348 and 540. Therefore. The upper surfaces of the bottom rings 804 and 812 are configured to combine with the upper surfaces of the middle rings 336 and 536 and complement the bottom surfaces of the edge rings 324 and 526 to form an intricate interface including multiple directional changes as described above.

在導引通道836包含陶瓷套筒844的示例(例如導引通道836係佈線穿過底板820的示例)中,底部環804、808、及812可配置成容納陶瓷套筒844。舉例而言,底部環804、808、及812可包含間隙特徵部,諸如具有大於導引通道836之直徑的空穴或切口856,以容納陶瓷套筒844的上端。在一些示例中,底部環804、808、及812可在升降銷840之後安裝。因此,底部環804、808、及812中的個別開口可包含倒角的邊緣860以促進底部環804、808、及812在升降銷840上的安裝。舉例而言,邊緣860的倒角可具有0.020”至0.035”的高度和寬度及40-50°的角度。In an example where the guide channel 836 includes a ceramic sleeve 844 (for example, an example in which the guide channel 836 is routed through the bottom plate 820), the bottom rings 804, 808, and 812 may be configured to receive the ceramic sleeve 844. For example, the bottom rings 804, 808, and 812 may include clearance features, such as cavities or cutouts 856 having a larger diameter than the guide channel 836, to accommodate the upper end of the ceramic sleeve 844. In some examples, the bottom rings 804, 808, and 812 may be installed after the lift pin 840. Therefore, the individual openings in the bottom rings 804, 808, and 812 may include chamfered edges 860 to facilitate the installation of the bottom rings 804, 808, and 812 on the lift pins 840. For example, the chamfer of the edge 860 may have a height and width of 0.020" to 0.035" and an angle of 40-50°.

如圖8B及8C所示,在862處之底部環808及812的階梯式內直徑係加以選擇以容納圖4C之邊緣環424及圖5B之邊緣環526的外直徑。舉例而言,邊緣環424及526的外直徑可為大約12.8”(例如:+/-0.10”)。因此,在862處之底部環808及812的內直徑可為至少13.0”。因此,可使底部環808和812與邊緣環424和526之外直徑之間的間隙最小化,而仍防止底部環808和812之垂直表面與邊緣環424和526之間的接觸。As shown in FIGS. 8B and 8C, the stepped inner diameters of the bottom rings 808 and 812 at 862 are selected to accommodate the outer diameters of the edge ring 424 of FIG. 4C and the edge ring 526 of FIG. 5B. For example, the outer diameter of the edge rings 424 and 526 may be approximately 12.8" (for example: +/-0.10"). Therefore, the inner diameter of the bottom rings 808 and 812 at 862 can be at least 13.0". Therefore, the gap between the outer diameters of the bottom rings 808 and 812 and the edge rings 424 and 526 can be minimized, while still preventing the bottom ring The contact between the vertical surfaces of 808 and 812 and the edge rings 424 and 526.

在一些示例中,如圖8B所示,底部環808可包含在864處的第一外直徑及在868處的第二外直徑。在868處的第二外直徑大於在864處的第一外直徑。舉例而言,基板支座800可包含襯墊872,該襯墊872保護絕緣體板816、底板820、底部環808等的外部部分。然而,襯墊872可能不保護曝露於電漿之底部環808的上部部分,且可能發生在毗鄰底板820之上邊緣876之區域中之底部環808之增加的腐蝕(如虛線箭頭880所示)。因此,底部環808包含在第二外直徑868處的額外材料以補償增加的腐蝕。In some examples, as shown in FIG. 8B, the bottom ring 808 may include a first outer diameter at 864 and a second outer diameter at 868. The second outer diameter at 868 is greater than the first outer diameter at 864. For example, the substrate support 800 may include a gasket 872 that protects the outer portions of the insulator plate 816, the bottom plate 820, the bottom ring 808, and the like. However, the liner 872 may not protect the upper part of the bottom ring 808 exposed to the plasma, and increased corrosion of the bottom ring 808 in the area adjacent to the upper edge 876 of the bottom plate 820 may occur (as indicated by the dashed arrow 880) . Therefore, the bottom ring 808 contains additional material at the second outer diameter 868 to compensate for the increased corrosion.

現參照圖9,顯示示例中間環900。中間環900可設置於頂部邊緣環在其他方面由基板支座之兩個不同部件的上表面加以支撐的配置中。舉例而言,如圖3B及5B所示(分別對應於圖8A及8C),頂部邊緣環與個別的陶瓷層及個別的底部環重疊。因此,中間環900係配置成支撐在其他方面由陶瓷層支撐之頂部邊緣環的一部分。如圖所示,中間環900係「U」形形狀。Referring now to Figure 9, an example intermediate ring 900 is shown. The middle ring 900 may be provided in a configuration where the top edge ring is otherwise supported by the upper surfaces of two different parts of the substrate support. For example, as shown in FIGS. 3B and 5B (corresponding to FIGS. 8A and 8C, respectively), the top edge ring overlaps the individual ceramic layer and the individual bottom ring. Therefore, the middle ring 900 is configured to support a portion of the top edge ring that is otherwise supported by the ceramic layer. As shown in the figure, the intermediate ring 900 has a "U" shape.

中間環900包含定義凹槽912的內環形邊緣904及外環形邊緣908。凹槽912係配置成容納個別的頂部邊緣環(例如邊緣環324或526)。相反地,外環形邊緣908作為導引特徵部,以如上面圖3B及5B所述在替換期間將頂部邊緣環324或526置中。在一些示例中,角隅916及920係加以倒角以促進與頂部邊緣環的接合。舉例而言,角隅916的倒角可具有至少大約0.010”(例如:0.005”至0.015”)的高度和寬度及大約20°(例如15-25°)的角度。角隅920的倒角可具有至少大約0.015”(例如:0.010”至0.020”)的高度和寬度及大約30°(例如25-35o )的角度。外環形邊緣908的寬度係加以選擇以使外環形邊緣908的個別垂直表面與邊緣環324或526之底部上的互補垂直表面之間的間隙最小化。舉例而言,間隙可小於0.010”以限制電漿洩漏。The middle ring 900 includes an inner annular edge 904 and an outer annular edge 908 that define the groove 912. The groove 912 is configured to receive an individual top edge ring (eg, edge ring 324 or 526). Conversely, the outer annular edge 908 serves as a guide feature to center the top edge ring 324 or 526 during replacement as described in Figures 3B and 5B above. In some examples, corners 916 and 920 are chamfered to facilitate engagement with the top edge ring. For example, the chamfer of corner corner 916 may have a height and width of at least about 0.010" (e.g., 0.005" to 0.015") and an angle of about 20° (e.g., 15-25°). The chamfer of corner corner 920 can be at least about 0.015 "(e.g.: 0.010" to 0.020 ") and the height and width angle of about 30 ° (e.g. 25-35 o) a. The width of the outer annular edge 908 is selected to minimize the gap between the individual vertical surface of the outer annular edge 908 and the complementary vertical surface on the bottom of the edge ring 324 or 526. For example, the gap can be less than 0.010" to limit plasma leakage.

現參照圖10A及10B,基板支座1000的兩個橫剖面圖描繪根據本揭示內容的原理設置成以階梯式的配置支撐頂部可運動的邊緣環之底部環1004。舉例而言,底部環1004係設置成以類似於圖5B及8C中顯示的配置支撐邊緣環(例如526)。底部環1004可進一步設置成以類似於與圖5B中顯示的配置支撐中間環。10A and 10B, two cross-sectional views of the substrate support 1000 depict a bottom ring 1004 configured to support a movable top edge ring in a stepped configuration according to the principles of the present disclosure. For example, the bottom ring 1004 is configured to support an edge ring (such as 526) in a configuration similar to that shown in FIGS. 5B and 8C. The bottom ring 1004 may be further configured to support the middle ring in a configuration similar to that shown in FIG. 5B.

基板支座1000包含絕緣體環或板1008及配置在絕緣體板1008上的底板(例如ESC的底板)1012。底板1012支撐陶瓷層1016,該陶瓷層1016係配置成支撐其上的基板以供處理。接合層1020可配置在底板1012與陶瓷層1016之間,且密封件1024圍繞接合層1020。如圖10A所示,一或更多貫孔或導引通道1028可穿過絕緣體板1008、底板1012、及底部環1004而形成,以容納配置成選擇性地升高及降低邊緣環的升降銷1032。舉例而言,導引通道1028作為升降銷1032之個別者的銷對準孔。升降銷1032與導引通道1028之內表面間的間隙係最小化以減少電漿洩漏。換句話說,導引通道1028的直徑係僅比升降銷1032的直徑稍大(例如大0.005”-0.010”)。舉例而言,升降銷1032可具有0.1”的直徑,而導引通道1028具有0.105”的直徑。在一些示例中,導引通道1028包含窄區域1036,其具有小於導引通道1028之其他部分的直徑以進一步限制電漿洩露。舉例而言,窄區域1036可具有比導引通道1028之直徑小0.002-0.004”的直徑。在一些示例中,一或更多陶瓷套筒1040可配置在圍繞升降銷1032的導引通道1028內。The substrate support 1000 includes an insulator ring or plate 1008 and a bottom plate (for example, a bottom plate of an ESC) 1012 disposed on the insulator plate 1008. The bottom plate 1012 supports a ceramic layer 1016, which is configured to support a substrate thereon for processing. The bonding layer 1020 may be disposed between the bottom plate 1012 and the ceramic layer 1016, and the sealing member 1024 surrounds the bonding layer 1020. As shown in FIG. 10A, one or more through holes or guide channels 1028 may be formed through the insulator plate 1008, the bottom plate 1012, and the bottom ring 1004 to accommodate lift pins configured to selectively raise and lower the edge ring 1032. For example, the guide channel 1028 serves as a pin alignment hole for each of the lifting pins 1032. The gap between the lift pin 1032 and the inner surface of the guide channel 1028 is minimized to reduce plasma leakage. In other words, the diameter of the guide channel 1028 is only slightly larger than the diameter of the lifting pin 1032 (for example, 0.005"-0.010" larger). For example, the lift pin 1032 may have a diameter of 0.1", and the guide channel 1028 has a diameter of 0.105". In some examples, the guide channel 1028 includes a narrow area 1036 that has a smaller diameter than other parts of the guide channel 1028 to further limit plasma leakage. For example, the narrow area 1036 may have a diameter 0.002-0.004" smaller than the diameter of the guide channel 1028. In some examples, one or more ceramic sleeves 1040 may be disposed in the guide channel 1028 surrounding the lift pin 1032 .

基板支座1000可包含襯墊1044,襯墊1044係配置成包圍及保護基板支座1000的元件,諸如絕緣體板1008、底板1012、及底部環1004。如圖10A及10B顯示的底部環1004包含自襯墊1044上的底部環1004徑向向外延伸的環形唇部1048。當襯墊1044係存在時,唇部1048促進底部環1004的安裝及移除。The substrate support 1000 may include a gasket 1044, which is configured to surround and protect the components of the substrate support 1000, such as an insulator plate 1008, a bottom plate 1012, and a bottom ring 1004. The bottom ring 1004 as shown in FIGS. 10A and 10B includes an annular lip 1048 extending radially outward from the bottom ring 1004 on the gasket 1044. When the liner 1044 is present, the lip 1048 facilitates the installation and removal of the bottom ring 1004.

如圖10B所示,底板1012可使用***個別螺栓安裝孔1056的螺栓1052耦接至絕緣體板1008。陶瓷栓塞1060係配置在螺栓1052上以防止螺栓安裝孔1056中及底部環1004與底板1012間的電漿洩露。如圖10B顯示的底部環1004包含間隙特徵部,諸如空穴或切口1064以容納陶瓷栓塞1060。As shown in FIG. 10B, the bottom plate 1012 may be coupled to the insulator plate 1008 using bolts 1052 inserted into individual bolt mounting holes 1056. The ceramic plug 1060 is arranged on the bolt 1052 to prevent the leakage of the plasma in the bolt mounting hole 1056 and between the bottom ring 1004 and the bottom plate 1012. The bottom ring 1004 as shown in FIG. 10B contains clearance features, such as cavities or cutouts 1064 to accommodate ceramic plugs 1060.
