PLASMA TREATMENT APPARATUS, PLASMA GENERATION APPARATUS, ANTENNA STRUCTURE AND PLASMA GENERATION METHOD

摘要

A plasma treatment apparatus is provided, which is capable of simplifying the configuration thereof and preventing the deterioration of plasma generation efficiency. The plasma treatment apparatus (10) comprises: a chamber (11); a mount (12) arranged inside the chamber (11) to mount a substrate (S); an ICP antenna (13) arranged to be opposite to the mount (12) outside the chamber (11) and connected to a high-frequency power source (26); and a window member (14) interposed between the mount (12) and the ICP antenna (13) and made up of a conductor, wherein the window member (14) is divided into a plurality of segments (27) and the segments (27) are insulated from each other and connected to a wire (29) or a wire (30) having a condenser attached thereto to form a closed circuit (31).
