Abstract
There is provided a plasma processing apparatus including a focus ring capable of preventing a part of a heat transfer sheet from adhering to and remaining on a mounting table. The plasma processing apparatus comprises: a chamber for performing a plasma process on a target object; a mounting table configured to mount thereon the target object; and a focus ring configured to surround the target object, the focus ring being in contact with the mounting table via a flexible heat transfer sheet. Further, the heat transfer sheet has a contact surface in contact with the mounting table and an anti-adhesion layer formed on the contact surface, and the anti-adhesion layer is located between said contact surface of the heat transfer sheet and a mounting surface of the mounting table. Furthermore, the anti-adhesion layer contains heat conductive particulates, and the heat transfer sheet is formed in an annular shape.
