Patent ID: 8636873

Claim:
A mounting table for mounting a target substrate, the mounting table comprising: a base member at least having a first surface, a second surface and a third surface; an electrostatic chuck provided on the first surface; and a hole formed through the base member and the electrostatic chuck and in which a lifter pin exposed to the second surface and the third surface is inserted, an inner surface of the hole including the second and the third surface, wherein a thermally sprayed insulating film is formed on the first surface, an insulating sleeve made of a material having a linear expansion coefficient different from that of the base member is provided on the second surface of the hole, and the third surface is covered with an insulating layer, wherein an inner diameter of the third surface is larger than that of the second surface, and wherein the insulating layer is interposed between the thermally sprayed insulating film and the insulating sleeve to prevent a contact therebetween, and is configured to prevent a stress from being imposed on the thermally sprayed insulating film due to the difference between the linear expansion coefficient of the base member and that of the insulating sleeve.
