摘要:
An electrostatic chuck includes a dielectric layer 30 formed with an attraction and fix face onto which a plate member 10 is attracted and fixed, wherein the attraction and fix face of the dielectric layer 30 is formed with a plurality of projection parts 32 each with only a tip face abutting the plate member 10 formed as a flat face by grinding and formed with a coolant gas flow path 36 where a coolant gas flows is opened to the flat face of each of the projection parts 32.
