Method for manufacturing substrate mounting table

摘要

A method for manufacturing a substrate mounting table having a mounting surface for mounting a substrate thereon; a plurality of gas injection openings opened on the mounting surface to supply a gas toward the mounting surface; a gas supply channel for supplying a gas to the gas injection openings; and a thermally sprayed ceramic layer covering the mounting surface is provided. The method includes forming a removable film at least on inner wall portions of the gas supply channel facing the gas injection openings; forming the thermally sprayed ceramic layer on the mounting surface; and removing the film.
