化學氣相沉積(Chemical Vapor Deposition, CVD)是一種在高溫或等離子體環境下,通過氣态前驅體在基底表面發生化學反應,生成固态薄膜材料的關鍵工藝技術。其核心原理是利用氣态物質在受熱基底上的化學反應,實現原子或分子級别的材料沉積。以下是其核心要素詳解:
前驅體輸送
揮發性金屬鹵化物(如SiCl₄、WF₆)或有機金屬化合物(如三甲基鋁)以氣态形式進入反應室。
示例:沉積氮化矽(Si₃N₄)時常用矽烷(SiH₄)與氨氣(NH₃)作為前驅體。
化學反應
前驅體在高溫(通常500–1200°C)或等離子體激活下分解或反應,生成活性物質(如原子、離子團)。
反應式示例(沉積多晶矽):
$$ ce{SiH4(g) ->[Delta] Si(s) + 2H2(g)} $$
表面沉積
活性物質在基底表面吸附、遷移并成核生長,形成緻密薄膜。副産物氣體(如HCl、H₂)被排出系統。
