Patent ID: 7393433

Claim:
A plasma processing apparatus, comprising: an electrostatic chuck having a conductive member that generates an electrostatic attraction for holding an object; an RF bias-introducing rod connected to a source of RF power; and a wiring member connecting said RF bias-introducing rod to said conductive member, in plan view, said wiring member having plural linear connectors and plural curved connectors, each of said linear connectors having one end connected to a same end of said RF bias-introducing rod and being substantially linear-symmetrical with respect to a straight line passing through a center of said conductive member, each of said curved connectors being substantially centrosymmetrical with respect to the center of said conductive member and having two distal ends and being connected to an opposite end of a respective different one of said linear connectors, and at least one of the distal ends of one of said curved connectors being connected to said conductive member.
