Abstract:
A film-forming apparatus comprises a substantially enclosed reaction chamber, a substrate holding means for arranging a substrate for film formation in said reaction chamber, a raw material gas introduction means for introducing a film-forming raw material gas into said reaction chamber, and a high frequency power introduction means for introducing a high frequency power into said reaction chamber, whereinsaid high frequency power introduction means comprises at least an electrode for introducing said high frequency power into said reaction chamber and an insulating member which covers a surface of said electrode such that the surface of said electrode is isolated from glow discharge caused in said reaction chamber;said electrode is provided with a plurality of gas election holes for ejecting a cooling gas against an inner face of said insulating member, said electrode having a hollow portion capable of serving as a passage for said cooling gas introduced therein, said hollow portion being communicated with said plurality of gas ejection holes; andsaid film-forming apparatus is provided with a gas introduction means for introducing said cooling gas into said hollow portion of said electrode.
