Description
本揭露內容相關於電漿處理基板的方法及設備。本揭露內容更尤其相關於在電漿處理腔室中夾持邊緣環的方法及設備。
在電漿處理中,具有邊緣環的電漿處理腔室可用以提供改善的製程控制。
為達成前述內容並根據本揭露內容的目的,本揭露內容提供在電漿處理腔室中利用靜電環卡盤以靜電方式夾持邊緣環的方法,該靜電環卡盤具有至少一環背面溫度通道,以提供氣體流至邊緣環,從而調節溫度。提供真空至該至少一環背面溫度通道。量測至少一環背面溫度通道中的壓力。當至少一環背面溫度通道中的壓力達到臨界最大值壓力時,提供靜電環夾持電壓。中斷至少一環背面溫度通道的真空。量測至少一環背面溫度通道中的壓力。若至少一環背面溫度通道中的壓力上升得比臨界速率快,則指示密封失效。若至少一環背面溫度通道中的壓力並非上升得比臨界速率快,則在利用至少一環背面溫度通道調節邊緣環之溫度的情況下,持續電漿製程。
在另一表現形式中,提供用於電漿處理腔室中的邊緣環,該電漿處理腔室具有靜電晶圓卡盤及靜電環卡盤,該靜電環卡盤具有中心孔,且冷卻溝槽圍繞該中心孔,且該靜電環卡盤具有介於該冷卻溝槽下方的環夾持電極及用以提供氣體流至冷卻溝槽以調節邊緣環之溫度的至少一環背面溫度通道。邊緣環包含邊緣環主體,其具有當該邊緣環主體定位靜電環卡盤上方時將定位於具有環夾持電極及至少一環背面溫度通道之靜電環卡盤上方的第一表面,其中該邊緣環主體包含定位於環夾持電極上方的導電部,其中,該第一表面具有中心孔及第一彈性體環,該第一彈性體環係整合至第一表面且圍繞該邊緣環主體之第一表面的中心孔,其中當該邊緣環定位該靜電環卡盤上方時,該第一彈性體環係用以密封該冷卻溝槽。
本發明的該等及其他特徵將於以下之本發明的實施方式中並結合以下圖示而更詳細地加以描述。
如附圖中所說明,本發明現在將參考本發明之若干較佳實施例詳細加以描述。在以下描述內容中,提出許多具體細節,以提供對本發明的透徹理解。然而,熟悉本技術領域者將明白,本發明可在沒有該等具體細節之一些或全部者的情況下實施。在其他情形中,已熟知的製程步驟及/或結構未詳細描述,以免不必要地模糊本發明。
圖1係在一實施例中可使用之電漿處理腔室的示意圖。在一或更多實施例中,電漿處理系統100在由腔室壁150所圍成的處理腔室149內包含提供氣體入口的氣體分佈板106以及含有陶瓷板112及基部板114的靜電卡盤系統(ESC系統, electrostatic chuck system)108。在處理腔室149內,基板104係定位於ESC系統108的頂部上。ESC系統108可提供來自ESC源148的偏壓。氣體源110係通過分佈板106連接至電漿處理腔室149。ESC溫度控制器151係連接至ESC系統108,且提供ESC系統108的溫度控制。真空源160係連接至ESC系統108。RF源130提供RF功率至ESC系統108及上電極,該上電極在此實施例中係氣體分佈板106。在一較佳實施例中, 2MHz、60MHz、及選用之27MHz電源構成RF源130。在此實施例中,針對每一頻率設置一產生器。在其他實施例中,產生器可處於單獨的RF源中,或者單獨的RF產生器可連接至不同的電極。例如,上電極可具有連接至不同RF源的內電極及外電極。在其他實施例中,可使用RF源及電極的其他設置,例如,在另一實施例中,上電極可接地。控制器135係可控制地連接至RF源130、ESC源148、排氣泵120、及蝕刻氣體源110。邊緣環116係於基板104的外邊緣處藉由ESC系統108而支撐。如此之電漿處理腔室的範例係由Lam Research Corporation of Fremont, CA製造的Exelan Flex
TM蝕刻系統。在諸多實施例中,製程腔室可為電容耦合電漿(CCP, capacitive coupled plasma)反應器、或電感耦合電漿(ICP, inductive coupled plasma)反應器、或可為另一類型的帶電電漿。

圖3係ESC系統108及基板104之部分的放大圖。ESC系統108包含陶瓷板112及基部板114。彈性體結合部304將陶瓷板112固定至基部板114。基板夾持電極308係在陶瓷板112之隆起中心部306中,該基板夾持電極308係用以施加電壓,從而以靜電方式夾持基板104。至少一基板夾持電極引線309係連接於基板夾持電極308與圖1中所示的ESC源148之間。邊緣環夾持電極312係在陶瓷板之下周邊部310中,該邊緣環夾持電極312係用以施加電壓,從而以靜電方式夾持邊緣環116。至少一邊緣環夾持電極引線314係連接於邊緣環夾持電極312與圖1中所示的ESC源148之間。在一實施例中,ESC源148可為複數電壓源。在另一實施例中,ESC源148可為具有複數開關的單一電壓源,以獨立地施加不同的電壓至基板夾持電極308及邊緣環夾持電極312。下周邊部310的一部分可下凹而形成間隙,該間隙係藉由下周邊部310與邊緣環116之間的冷卻溝槽350而形成。冷卻溝槽350提供容許冷卻劑流動於邊緣環116之背側附近、且有助於產生冷卻劑之密封部的區域。
複數基板背面溫度通道320係在隆起中心部306中,該等基板背面溫度通道320係透過流體連接部324連接至圖1中所示的ESC溫度控制器151。複數環背面溫度通道328係在下周邊部310中,該等環背面溫度通道328係透過流體連接部332連接至圖1中所示的ESC溫度控制器151。下周邊部310之上表面中的第一密封溝槽336形成圍繞隆起中心部306的環。下周邊部310之上表面中的第二密封溝槽340形成圍繞第一密封溝槽336且與該第一密封溝槽336同心的環。
邊緣環116包含邊緣環主體394、及整合至邊緣環主體394的第一彈性體環344、及整合至邊緣環主體394的第二彈性體環348。圖4係邊緣環116的仰視圖。邊緣環116的底部形成第一表面404,其亦顯示於圖3中。邊緣環116具有外直徑408及內直徑412。在此範例中,外直徑為400 mm,且內直徑為290 mm。邊緣環116的中心孔係在內直徑以內。在此範例中,邊緣環116係由矽形成,使得邊緣環116(包含第一表面404)係具有導電性的。在此範例中,如所示,第一彈性體環344、及第二彈性體環348、及邊緣環116均為同心。如所示,邊緣環116之中心部中的孔形成中心孔。
邊緣環夾持電極312形成靜電環卡盤。基板夾持電極308形成靜電晶圓卡盤。若整個邊緣環116或第一表面404不導電,則邊緣環116將需要具有導電部分。如圖3中所示,當邊緣環116係安裝於靜電環卡盤上,使得邊緣環116的導電部分在邊緣環夾持電極312之上且隆起中心部306穿過中心孔時,第一彈性體環344係定位於第一密封溝槽336中,且第二彈性體環348係定位於第二密封溝槽340中。
在此範例中,第一密封溝槽336及第二密封溝槽340具有0.5 mm的深度。第一彈性體環344及第二彈性體環348在夾持之後具有0.5 mm之高度。
圖5係夾持邊緣環116之製程的高階流程圖。邊緣環116係定位於靜電環卡盤上(步驟504)。如圖1及圖3中所示,邊緣環116可定位於靜電環卡盤上。靜電環卡盤係藉由邊緣環夾持電極312形成。陶瓷板112之下周邊部310、下周邊部310之上表面中的第一密封溝槽336、下周邊部310之上表面中的第二密封溝槽340、冷卻溝槽350、及複數環背面溫度通道328可進一步構成靜電環卡盤。真空係藉由將流體連接部332連接至真空源160而提供至複數環背面溫度通道328(步驟508)。真空源160提供真空,這使得邊緣環116向下周邊部310的上表面移動,這使得第一彈性體環344及第二彈性體環348分別被壓縮於第一密封溝槽336及第二密封溝槽340內。較佳地,腔室壓力係大氣壓力,使得邊緣環116之頂部上的壓力為大氣壓力。所施加的真空導致邊緣環116的機械移動,以輔助邊緣環116的靜電夾持並容許密封測試。量測背面溫度通道中的壓力。當該壓力低至臨界壓力時,施加環夾持電壓(步驟512)。壓力臨界值表示邊緣環116已被壓迫至臨界距離,這將容許邊緣環夾持電極312夾持邊緣環116。然後中斷施加真空(步驟516)。量測背面溫度通道328中的壓力(步驟520)。若所量測之壓力增加大於臨界速率,這表示密封失效(步驟524)。然後,必須重新建立密封(步驟528)。這可藉由重新安置邊緣環而完成。這可能需要更換邊緣環116,使得第一彈性體環344及第二彈性體環348受到更換。若所量測之壓力增加的小於臨界速率,這表示充分密封。然後,使用背面溫度通道328進行邊緣環116的溫度控制(步驟532)。在基板於ESC系統之基板夾持電極上方的定位期間,且在基板的夾持期間、基板的處理期間、基板的鬆開期間、及基板的移除期間,邊緣環夾持電極持續地夾持邊緣環。因此,環夾持電極及基板夾持電極係獨立操作,以容許當將基板夾持電極用以夾持及後續鬆開基板時,環夾持電極持續地進行夾持。
此實施例提供邊緣環密封,這容許邊緣環的溫度控制。容許邊緣環的溫度控制在電漿處理期間提供較大的控制,這改善電漿處理。
此實施例提供優於利用O形環之配置的諸多優點。為了將O形環用於類似目的,O形環將需為薄而具有大直徑,且需由軟性材料製成。由於O形環的脆弱及建立密封的諸多要求(例如,防止O形環的夾緊或聚攏),故將如此之O形環定位成產生期望的密封將需要高度熟練的技術人員。此實施例容許較不熟練的技術人員簡單且輕易地將邊緣環定位於靜電環卡盤上。
在其他實施例中,陶瓷板可呈兩部分,隆起中心部306係與下周邊部310分隔開。整個邊緣環可由例如矽之具有導電性的材料製成。在其他實施例中,邊緣環係具有導電部件的介電材料,當該邊緣環定位於靜電環卡盤上時,該導電部件將定位於環夾持電極上方。導電部件有助於靜電夾持。較佳地,邊緣環係矽、矽碳化物、或石英其中至少一者。
在諸多實施例中,每一彈性體環的高度比該彈性體環所定位於其中的溝槽的深度更大。這導致在建立密封時,彈性體環被壓縮,這有助於建立密封。在諸多實施例中,彈性體環可具有不同的橫剖面。較佳地,彈性體環的橫剖面係長方形、方形、三角形、梯形、或半圓形其中至少一者。更佳地,彈性體環之橫剖面的底部比與(與邊緣環之其他部分整合之)彈性體環的頂部更窄。最佳地,如圖3中所示,彈性體環係梯形。較佳地,彈性體環具有介於0.25 mm至2 mm之間的高度。較佳地,彈性體環的高度比溝槽的深度大10至50微米之間。較佳地,彈性體環之高度的公差係50微米以下。更佳地,彈性體環之高度的公差係12~13微米。較佳地,邊緣環的外直徑介於200 mm至450 mm之間。更佳地,邊緣環的外直徑介於300 mm至400 mm之間。較佳地,邊緣環、第一彈性體環、及第二彈性體環係同心的。較佳地,第一彈性體環係位於邊緣環之內邊緣的10 mm以內,且第二彈性體環係位於邊緣環之外邊緣的30 mm以內。
在夾持晶圓時,不需要彈性體環,因為晶圓將彎曲而輔助建立密封。因為邊緣環比晶圓厚的多,故在沒有彈性體環的情形中,邊緣環不足夠彎曲成建立密封。在一些實施例中,彈性體環可藉由在邊緣環上施加濕彈性體或液體彈性體以及然後使邊緣環上的彈性體乾燥或固化及硬化而形成。在諸多實施例中,彈性體環係由漏氣不超過特定限制的軟性彈性體製成,例如聚矽氧。較佳地,彈性體環包含具有至少200 mm之環直徑及介於0.25 mm至2 mm間之高度的聚矽氧。較佳地,彈性體之橫剖面的厚度小於3 mm。較佳地,彈性體環包含具有至少200 mm之直徑及介於0.25 mm至1.5 mm間之高度的聚矽氧。陶瓷板之表面中的溝槽容許邊緣環的表面定位於靜電環卡盤附近,以容許夾持動作。在彈性體環之一些壓縮的情況下,彈性體環的高度及溝槽的深度沿著彈性體環的周邊提供氣體密封,且同時補償邊緣環之20微米的不平整度(這需要額外之20微米的彈性體壓縮(彈性體壓縮係彈性體密封件的高度減去溝槽深度))。陶瓷板之表面中的選用特徵部在陶瓷板的表面及邊緣環之間提供10微米間隙。間隙可在從0微米至20微米的範圍內。
在一實施例中,彈性體的高度等於溝槽的深度加溝槽深度的公差加彈性體密封件高度的公差(全部假設為對稱公差)加邊緣環的平整度。因此,若溝槽深度為0.5 mm±25 μm,彈性體密封件可控制在目標高度的±15 μm以內,且環的平整度為20 μm,則彈性體密封件目標高度應為0.5 mm+25 μm+15 μm+20 μm=0.56 mm。這確保了當彈性體在其最小高度、且溝槽在其最大深度、且平整度為最差時,密封件仍將接觸溝槽之底部處的環表面。由於不可能所有的部件皆同時為最差情形,故吾人有時使用RSS加法,在此情形中,彈性體密封件目標高度應為0.5 mm+平方根(25 μm
2+15 μm
2+20 μm
2)=0.535 mm。
在一實施例中,邊緣環具有至少1 mm的厚度,以容忍電漿處理期間的磨損,且提供高度方面的靈活性。在一些實施例中,邊緣環具有介於晶圓之上表面以上的上表面,以提供鞘控制。
較佳地,背面溫度控制通道係承載氦氣冷卻劑的氦通道。冷卻劑係用以冷卻基板及邊緣環二者。如此之實施例容許基板及邊緣環二者的溫度控制。此外,實施例容許基板及邊緣環之單獨的溫度控制。在其他實施例中,其他氣體或液體可用作冷卻劑,例如氬、空氣、氮、或具有極低蒸氣壓的液體。
圖6係另一實施例中ESC系統108及基板104之部分的放大圖。ESC系統108包含陶瓷板112及基部板114。彈性體連接部604將陶瓷板112固定至基部板114。在此實施例中,陶瓷板112包含中心基板支撐部606及周邊環形狀的邊緣環支撐部610。圓形冷卻溝槽650係在陶瓷板112的邊緣環支撐部610中,該圓形冷卻溝槽650圍繞基板支撐部606及邊緣環支撐部610的中心孔。邊緣環夾持電極612係在冷卻溝槽650的底部下方,該邊緣環夾持電極612係用以施加電壓,以靜電夾持邊緣環116。至少一邊緣環夾持電極引線614係連接於邊緣環夾持電極612與圖1中所示的ESC源148之間。當邊緣環116定位於邊緣環支撐部610上時,冷卻溝槽650將在邊緣環支撐部610與邊緣環116之間產生間隙。
複數環背面溫度通道628係在邊緣環支撐部610中,該複數環背面溫度通道628係透過流體連接部632連接至圖1中所示的ESC溫度控制器151且連接至冷卻溝槽650。邊緣環116具有整合至該邊緣環116的彈性體環644。在此範例中,彈性體環644係呈形成環件的片狀。較佳地,該片不超過25微米厚,且寬度大於冷卻溝槽650的寬度。
邊緣環夾持電極612、冷卻溝槽650、及邊緣環支撐部610形成靜電環卡盤。如圖6中所示,當邊緣環116安裝於靜電環卡盤上,使得邊緣環116的導電部位於邊緣環夾持電極612上方,且中心基板支撐部606穿過中心孔時,彈性體環644如所示延伸跨過冷卻溝槽650。
