201234461 、發明說明: 相關申請案之交叉引用 本申請案係於2011年1月18日提出申請之標題名稱 為「SEMICONDUCTOR PROCESSING SYSTEM AND METHODS USING CAPACITIVELY COUPLED PLASMA」 之美國臨時專利申請案第61/433,633號之正式案且主張 該臨時專利申請案之申請曰期之權益,為達成所有目 的,該臨時專利申請案之全部揭示内容以引用之方式全 部併入本文。 【發明所屬之技術領域】 本發明係關於半導體製造系統。 【先前技術】 用於製造半導體積體電路之電漿沉積及蝕刻製程已廣 泛使用數十年。此等製程通常包含自產生電漿之氣體中 形成電漿,產生電漿之氣體暴露於處理腔室内部之功率 充足之電場中以使得氣體離子化。使此等氣體形成為電 漿所需之溫度可遠低於以熱方式離子化相同氣體所需之 溫度。因此,電漿產生製程可用來在顯著低於可能藉由 簡單加熱氣體進行之腔室處理溫度下自啟動氣體產生反 應性自由基及離子種類。此允許電漿自基板表面沉積及/ 或敍刻材料而無需將基板溫度上升至臨限值之上,將基 板溫度上升至臨限值之上將熔融、分解或者以其他方式 損壞基板上之材料。 201234461 示例性電毁沉積製程包括在基板晶圓之暴露表面上諸 如氧化矽之介電性材料的電漿輔助化學氣相沉積 (plasma-enhanced chemical vapor deposition; PECVD) ° 習知PECVD包含混合處理腔室内之氣體及/或沉積前驅 物’及自氣體觸發電漿以產生在基板上反應且沉積材料 之反應種類。電漿通常接近於基板之暴露表面定位以促 進反應產物之有效沉積。 類似地’電漿蝕刻製程包括暴露基板之經選擇部分至 電漿活化之蝕刻種類,活化之蝕刻種類在化學上發生反 應及/或在物理上濺射基板之材料。電漿蝕刻之材料的移 除速率、選擇率及方向可利用對姓刻劑氣體、電漿激發 月&及在基板與帶電電漿種類之間的電偏置以及其他參數 之調整來進行控制》—些電漿技術,諸如高密度電漿化 學氣相 >儿積(high-density plasma chemical vapor deposition; HDP-CVD)依靠同步的電漿蝕刻及沉積以產 生基板上之特徵結構。 儘官通常電漿環境對基板之破壞少於高溫沉積環境, 但是電漿環境仍產生製造挑戰。由於高能電漿過蝕刻淺 溝及間隙,所以蝕刻精度可能成為問題。電漿中之高能 種類,尤其離子化種類可在經沉積材料中產生非所欲反 應,非所欲反應不利地影響材料之效能❶因此,需要於 製造期間對接觸基板晶圓之電漿部件提供更精確控制之 系統及方法。 5 201234461 【發明内容】 系統及方法經描述以用於在電毁與暴露於電漿及/或 電聚之流出物的其姑曰間士 的基板H曰圓表面之間的環境之改良控制。 改良控制可藉由定位在電漿與基板之間的離子抑制元件 至少部分地實現,離子抑制元件減少或消除到達基板之 離子帶電種類之數目。在基板上之電漿辅㈣刻及/或沉 積』門調整到達基板表面之離子種類之濃度允許對鞋 刻速度ϋ刻選擇率及沉積化學性冑(以及其他參數) 之更精確控制。 在一些實财’離子抑制元件可為基板處理腔室之氣 體/前驅物輸送設備之部分。舉例而言,定位在電榮區域 與基板之間的腔室内部之喷淋頭可既作為氣體及前驅物 之分配部件又作為離子抑制器,料抑制器減少穿過噴 淋頭自電漿區域前進至基板之離子化種類之數量。在額 外實例中,離子抑制元件可為在電漿區域與基板之間的 具有一或更多開孔之隔板,電漿流出物可經由開孔自電 聚區域傳遞至基板。開孔之尺寸、位置及幾何形狀、隔 板與基板之間的距離以及隔板上之電偏置以及其他特性

過渡區域724。錐形區域724實質上可防止電漿725穿 透通孔702。舉例而言,當電漿725穿透進入通孔72〇 時,離子種類可藉由接觸錐形區域724之壁來阻止或接 地,從而限制穿過通孔之電漿流通並使電漿包含在通孔 720上方的區域内。然而,自由基或中性粒子種類可穿 過通孔720。因此,通孔72〇可過濾電漿72〇以防止或 控制非所欲種類之流通。在示例性實施例中,通孔之較 小ID區域726包含i mm或更小之ID。為保持穿透通 孔之自由基及/或中性粒子種類之顯著濃度,可控制較小 ID區域之長度及/或錐形角度。 除防止電聚流通之外’本文所述之通孔亦可用來調節 電漿流通以便允許期望等級之電漿穿過通孔。調節穿過 通孔之電漿流動可包括增加在離子抑制器平板上方的氣 體區域中之電聚壓力,以便期望比例之電毁能夠穿過離 子抑制器而不受阻止或接地。 現在參閱第8 β ’第8圖圖示電容耦合式電漿(ccp)

之間過渡的錐形區域826。當電漿穿透入通孔8〇6時, 在第三ID區域824與出口 ID之間的錐形區域826及/ 或在第二ID區域與第三ID區域(分別為822及824 ) 之間的倒角邊緣可藉由阻止離子種類或使離子種類接地 來防止電漿回流。 類似地,底部平板804可包括通孔808,通孔808允 許自由基或中性粒子種類穿過通孔,同時防止或控制離 子種類之流通。通孔808可類似於通孔720配置,通孔 8〇8具有較大ID區域830、較小ID區域832及在較大 ID區域830與較小ID區域832之間過渡的錐形區域 834。錐形區域834可如先前所說明地藉由阻止或使離子 種類接地來防止穿過通孔808之電漿流動,同時允許自 由基或中性粒子種類穿過通孔808。 為進一步防止穿過通孔之電漿流通,802及/或804, 頂部平板802及/或底部平板804可接收電荷來電性偏置 電漿並使電漿包含在電漿產生區域810内及/或調整穿 過底部平板之活化氣體中的離子濃度。使用CCP單元 27 201234461 800令之頂部平板802及底部平板804,可在電漿產生區 域810中實質上產生及/或保持電漿,同時將自由基及中 性粒子種類輪送至氣體反應區域以與一或更多前驅物氣 體進行混合,從而蝕刻基板表面上之材料或在基板表面 上沉積材料。 藉由已描述之若干實施例,熟習此項技術者將認識
