Description
図1を参照し、実施形態の成膜方法を実施可能な処理装置の一例について説明する。図1に示されるように、処理装置1は、複数の基板に対して一度に処理を行うバッチ式の装置である。基板は、例えば半導体ウエハ(以下単に「ウエハW」という。)であってよい。
図2を参照し、実施形態の成膜方法の一例について説明する。以下では、前述の処理装置1においてシリコン窒化膜(SiN膜)を成膜する場合を例に挙げて説明する。以下の成膜方法は、制御部80が処理装置1の各部の動作を制御することにより実施される。
前述の実施形態の成膜方法により成膜したシリコン窒化膜の膜特性を評価した実施例について説明する。実施例では、TSAの供給とN2の供給とを交互に繰り返すことによりウエハWの表面にシリコン窒化膜を成膜し、該シリコン窒化膜の膜特性を評価した。また、比較例として、ジクロロシラン(DCS)の供給とプラズマにより活性化したアンモニア(NH3)の供給とを交互に繰り返すことによりウエハWの表面にシリコン窒化膜を成膜し、該シリコン窒化膜の膜特性を評価した。
