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. |
