ELECTROSTATIC CHUCK AND MANUFACTURING METHOD THEREFOR
Last updated:
Abstract:
The present invention relates to a method for manufacturing an electrostatic chuck comprising: a base member of a metal material; and a dielectric layer, formed on an upper surface of the base member, including an electrode layer to the inside of which a DC power is applied. According to the present invention, the dielectric layer is formed of a ceramic material by using at least one selected from among a plasma spraying method and a sol-gel method, and thus can be provided with low porosity to increase in lifespan, and with high permittivity to increase in adhesion force to a substrate.
