Patent ID: 7567421

Claim:
A bipolar electrostatic chuck, comprising: a chuck main body having a mounting surface; an annular electrode member which is formed in an annular configuration with a center opening and is fixed onto the mounting surface; an inner electrode member which is disposed at a given clearance from the annular electrode member within the center opening of the annular electrode member and is fixed onto the mounting surface; and an outer electrode member which is disposed at a given clearance from the annular electrode member outside of the annular electrode member and is fixed onto the mounting surface wherein, at the time of assembling, the annular electrode member, the inner electrode member, and the outer electrode member are fixed onto the mounting surface through an adhesive layer, the inner electrode member and the outer electrode member constitute a first electrode, and the annular electrode member constitutes a second electrode, and after use, the annular electrode member, the inner electrode member, and the outer electrode member can be separated from the mounting surface by removing the adhesive layer, and wherein the adhesive layer is made of the silicone-based adhesive agent, and after use, the annular electrode member, the inner electrode member, and the outer electrode member can be separated from the mounting surface by removing the adhesive layer using a release agent.
