Abstract

An electrostatic chuck having an essentially flat film electrode which is essentially parallel to the chucking surface of the electrostatic chuck is fabricated by depositing a film electrode, preferably by screen printing, onto a surface of a sintered ceramic substrate. A green ceramic layer is formed or molded onto the film electrode and the resulting structure is sintered, thereby producing the electrostatic chuck.
