Abstract:
A film-forming method comprising the steps of spacedly arranging a plurality of substrates on a common circumference in a substantially enclosed reaction chamber so as to establish an inner space circumscribed by said plurality of substrates in said reaction chamber, introducing a film-forming raw material gas into said inner space and applying a high frequency power into said inner space, whereby plasma discharge is generated to cause the formation of a deposited film on each of said plurality of substrates,wherein a first electrode is arranged at a central position in said inner space circumscribed by said plurality of substrates, a second electrode is arranged outside said plurality of substrates arranged on said common circumference, and a shielding member having a dielectric portion constituted by a dielectric material is arranged between said second electrode and said plurality of substrates on said common circumference to substantially shield said film-forming raw material gas so that said film-forming raw material gas is confined inside said shielding member and transmit a high frequency power supplied to said second electrode into said inner space while applying a high frequency power to said first electrode, whereby plasma discharge is generated in said inner space to cause the formation of said deposited film on each substrate.
