style="text-indent:25px">熱氧化與化學氣相沉積不同，她是通過氧氣或水蒸氣擴散到硅表面并進行化學反應形成氧化硅。熱氧化形成氧化硅時，會消耗相當于氧化硅膜厚的45%的硅。熱氧化氧化過程主要分兩個步驟：步驟一：氧氣或者水蒸氣等吸附到氧化硅表面，步驟二：氧氣或者水蒸氣等擴散到硅表面，步驟三：氧氣或者水蒸氣等與硅反應生成氧化硅。熱蒸發(fā)主要是三個過程：1.蒸發(fā)材料從固態(tài)轉化為氣態(tài)的過程。2.氣化原子或分子在蒸發(fā)源與基底之間的運輸 3.蒸發(fā)原子或分子在襯底表面上淀積過程，即是蒸汽凝聚、成核、核生長、形成連續(xù)薄膜的過程。</p><p style="text-indent:25px">熱氧化是在一定的溫度和氣體條件下，使硅片表面氧化一定厚度的氧化硅的。主要有干法氧化和濕法氧化，干法氧化是在硅片表面通入氧氣，硅片與氧化反應生成氧化硅，氧化速率比較慢，氧化膜厚容易控制。濕法氧化在爐管當中通入氧氣和氫氣，兩者反應生長水蒸氣，水蒸氣與硅片表面反應生長氧化硅，濕法氧化，速率比較快，可以生長比較厚的薄膜。對于薄膜應力主要有以下原因：1.薄膜生長初始階段，薄膜面和界面的表面張力的共同作用；2.沉積過程中膜面溫度遠高于襯底溫度產生熱應變；3.薄膜和襯底間點陣錯配而產生界面應力；4.金屬膜氧化后氧化物原子體積增大產生壓應力；5.斜入射造成各向異性成核、生長；6.薄膜內產生相變或化學組分改變導致原子體積變化。利用PECVD生長的氮化硅薄膜臺階覆蓋性比較好。</p><div

style="text-indent:25px">PECVD，等離子體化學氣相沉積法是借助微波或射頻等使含有薄膜組成原子的氣體電離，使局部形成等離子體，而等離子體化學活性很強，兩種或多種氣體很容易發(fā)生反應，在襯底上沉積出所期待的薄膜。為了使化學反應能在較低的溫度下進行，利用了等離子體的活性來促進反應，因此，這種CVD稱為等離子體增強化學氣相沉積。真空鍍膜的工藝流程：真空鍍膜的工藝流程一般依次為：前處理及化學清洗（材料進行有機清洗和無機清洗）→襯底真空中烘烤加熱→等離子體清洗→金屬離子轟擊→鍍金屬過渡層→鍍膜（通入反應氣體）。薄膜中存在的各種缺陷是產生本征應力的主要原因，這些缺陷一般都是非平衡缺陷，有自行消失的傾向。黑龍江叉指電極真空鍍膜加工</p><p
