Description
図1~図3を参照し、実施形態のプラズマパージ方法を実施する成膜装置の一例について説明する。成膜装置1は、原子層堆積(ALD:Atomic Layer Deposition)法又は分子層堆積(MLD:Molecular Layer Deposition)法により、基板の表面に酸化シリコン(SiO2)膜を形成する装置である。基板は、例えば半導体ウエハ(以下「ウエハW」という。)である。ウエハWの表面には、例えばトレンチ、ビア等の窪みパターンが形成されている。
図4~図7を参照し、実施形態のプラズマパージ方法の一例について説明する。実施形態のプラズマパージ方法は、真空容器11内のドライクリーニングの後であり、ウエハWに成膜処理を施す前に行われる。よって、実施形態のプラズマパージ方法は、回転テーブル12の表面上にウエハWが載置されていない状態で行われる。
図9を参照し、成膜装置1において実施される一連の全体の処理の一例について説明する。一連の全体の処理は、実施形態のプラズマパージ方法を含む。
図10及び図11を参照し、前述の成膜装置1を用いて実施した実施例について説明する。
