Abstract:
1. A plasma film forming apparatus for forming a film on a substrate using plasma, comprising: a processing container for processing the substrate accommodated therein; a mounting unit for mounting the substrate thereon in said processing container; a high frequency wave supply unit for supplying a high frequency wave for plasma generation into said processing container; a flat-plate structure provided between said high frequency wave supply unit and said mounting unit and partitioning an inside of said processing container into a region on said high frequency wave supply unit side and a region on said mounting unit side; and a plasma excitation gas supply port for supplying a plasma excitation gas at least from a lower side of the region on said high frequency wave supply unit side toward a central portion of the region on said high frequency wave supply unit side, wherein said structure is formed with a source gas supply port for supplying a source gas for film formation into the region on said mounting unit side and an opening for allowing plasma generated in the region on said high frequency wave supply unit side to pass to the region on said mounting unit side.
