发明名称 TABLE FOR PLASMA PROCESSING APPARATUS AND PLASMA PROCESSING APPARATUS
摘要 An object of the present invention is to suppress damage of an electrostatic chuck, by controlling stress exerted on each part of a table, which includes an electrically conductive material, i.e., an electrode for generating plasma, a dielectric layer for enhancing the in-plane uniformity of a plasma process, and an electrostatic chuck. The table for a plasma processing apparatus includes an electrically conductive member connected with a high frequency power source and adapted for plasma generation, for drawing ions present in the plasma, or for both thereof; a dielectric layer provided on a top face of the electrically conductive member, having a central portion and a peripheral portion that are different in thickness relative to each other, and adapted for providing uniformity of high frequency electric field intensity in a plane over the substrate to be processed; and an electrode film for an electrostatic chuck, provided in the dielectric layer and adapted for electrostatically chucking the substrate onto a top face of the dielectric layer. With such configuration, the stress exerted on the electrostatic chuck due to temperature change can be controlled.
