Abstract
A plasma processing system may include a vacuum vessel, a substrate table arranged in the vacuum vessel, and a radio-frequency power supply system for generating high-frequency waves. A waveguide may be provided for guiding high-frequency waves into the vacuum vessel, and a dielectric member may be arranged at an end portion of the waveguide. The plasma processing system may also include a conductive film arranged on the dielectric member and facing the substrate table, wherein the conductive film may have a thickness smaller than or approximately equal to a skin thickness of the conductive film.
