Abstract:
1. An electrostatic chuck device for electrostatically attracting a substrate to be processed, the device comprising; a susceptor having a top surface; plural chuck electrodes for electrically attracting said substrate to said top surface of said susceptor, said chuck electrodes arranged in the inside of said susceptor; a diselectrifying electrode for diselectrifying said substrate, said diselectrifying electrode arranged on said susceptor so as to be capable of contacting a back surface of said substrate placed on said susceptor; a diselectrifying potential source; a diselectrifying resistance connected between said diselectrifying electrode and said diselectrifying potential source; wherein said diselectrifying electrode is connected to a unit which can move said diselectrifying electrode in a direction toward the top surface of said susceptor.
