Abstract:
A deposited film-forming process for forming under vacuum a deposited film on a substrate arranged in a reaction chamber and having a glow discharge region by introducing a raw material gas into said reaction chamber and introducing a high frequency power into said reaction chamber to cause glow discharge in said glow discharge region of said reaction chamber thereby forming said deposited film on said substrate, comprising:introducing said high frequency power into said reaction chamber employing a high frequency power introduction means having an electrode for transmitting said high frequency power; and providing a region where impedance is discontinuous by employing the electrode which comprises electrically conductive metallic material and being patterned in a configuration which is branched into plural portions such that the region where impedance is discontinuous is provided so as to generate a uniform supply of said high frequency power to said reaction chamber, said high frequency power introduction means has (i) a first insulating surface in contact with said electrode such that there is no clearance between said electrically conductive metallic material constituting said electrode and said first insulating surface and (ii) a second insulating surface for insulating said electrically conductive metallic material constituting said electrode from said glow discharge region of said reaction chamber.
