Abstract:
A film-forming apparatus comprising a substantially enclosed reaction chamber having a reaction space in which a plurality of substrates are capable of being arranged on a common circumference so as to establish an inner space circumscribed by said plurality of substrates, and a means for introducing a film-forming raw material gas into said inner space,wherein a first electrode for supplying a high frequency power into said inner space is provided at a central position in said inner space circumscribed by said plurality of substrates, a second electrode is provided outside said plurality of substrates arranged on said common circumference, and a shielding member having a dielectric portion constituted by a dielectric material is provided between said second electrode and said plurality of substrates arranged on said common circumference such that said shielding member substantially shields said film-forming raw material gas so that said film-forming raw material gas is confined inside said shielding member and transmits a high frequency power supplied to said second electrode into said inner space.
