Abstract:
1. A plasma processing apparatus comprising: a processing chamber having a processing space therein; a stage provided within the processing chamber; a dielectric member, having a through hole, provided to face the stage; a microwave introduction device comprising a coaxial waveguide and configured to introduce microwave into the processing space via the dielectric member; an injector, having at least one through hole, made of a dielectric material and provided within the dielectric member; and an electric field shield within the dielectric member and enclosing the injector, wherein the coaxial waveguide, the injector and the through hole of the dielectric member form a path for supplying a processing gas into the processing space, and the electric field shield is extended downwardly from an upper surface of the injector to a position that is within the dielectric member and closer to the processing space than a bottom surface of the injector.
