Claim Text:
1. A mounting table structure that mounts thereon a processing target object on which a metal film is formed by a plasma sputtering process and is surrounded by a protective cover member installed within a processing chamber and connected to a ground side with an insulation gap therebetween, the mounting table structure being installed within the processing chamber, the mounting table structure comprising: a mounting table body, made of a conductive material, for mounting thereon the processing target object and serving as an electrode; a base table, made of a conductive material, disposed below the mounting table body with a gap therebetween in a state insulated from the mounting table body; a support column, connected to the ground side, for supporting the base table; a high frequency power supply line, connected to the mounting table body, for supplying a high frequency bias power to the mounting table body; and a power stabilization capacitor provided within the processing chamber and provided between the base table and the mounting table body, wherein the power stabilization capacitor includes: a plurality of screw members made of a conductive material and configured to penetrate the mounting table body; and an insulating member configured to cover a side surface and a top surface of each screw member, and the plurality of screw members are fixed to the base table.
