STRUCTURE OF SUBSTRATE SUPPORTING TABLE, AND PLASMA PROCESSING APPARATUS

摘要

Disclosed is the structure of a substrate supporting table wherein corrosion of a bellows is eliminated, generation of dusts from the bellows is suppressed, and the volume and the weight of the sections to be driven are reduced. A plasma processing apparatus is also disclosed. In the substrate supporting table for the plasma processing apparatus (10), a cylindrical inner tube (12), the bellows (13), an outer tube (14) and a cover member (15) are sequentially disposed concentrically from the inner side, and a drive member (21) to be driven by means of a drive mechanism (24) is attached to the rear surface of the placing table (16) through an opening (llb) and the inside of the inner tube (12).
