摘要： The susceptor of a plasma treating device, or the electrostatic chuck of a substrate table, is formed by ceramic thermal spray method. A thermally sprayed ceramic layer is pore-sealed by methacrylic resin. Resin raw material mainly containing methyl methacrylate is applied to and impregnated into the thermally sprayed ceramic layer and then is cured to thereby fill pores between ceramic particles in the thermally sprayed ceramic layer with methacrylic resin. Methacrylic resin raw material solution, which does not produce pores at curing, can complete perfect pore sealing.

摘要： A sample table which stably holds a semiconductor wafer by maintaining smoothness of a contact surface via a lapping process and forming the contact surface to have an approximate recess shape, and a microwave plasma processing apparatus including the sample table. The sample table holds a semiconductor wafer on which a plasma process is to be performed, and includes: an adsorption plate that has a contact surface on which a lapping process has been performed and surface-contacting the semiconductor wafer, and that adsorbs the semiconductor wafer; and a supporting substrate which has a recess surface to which a noncontact surface of the adsorption plate is adhered, wherein a difference between a depth of an approximate center portion of the recess surface and a depth of a distant portion spaced apart from the approximate center portion is larger than a difference between a thickness of the adsorption plate at a portion contacting the approximate center portion and a thickness of the adsorption plate at a portion contacting the distant portion. Also, a microwave plasma processing apparatus includes the sample table.
