Patent ID: 10475687

Abstract:
An aspect of the present invention has an object to provide an electrostatic chuck device which is provided with a plurality of divided heaters and in which uniform temperature control of a zone which is heated by each heater can be performed with a simple configuration. An electrostatic chuck device according to an aspect of the present invention includes: an electrostatic chuck part which has a mounting surface on one principal surface thereof to mount a plate-shaped sample and has an electrode for electrostatic attraction; a temperature controlling base part which is provided at a side opposite to the mounting surface of the electrostatic chuck part and is configured to cool the electrostatic chuck part; a high frequency generating electrode which is provided in a layer between the electrostatic chuck part and the temperature controlling base part; a high frequency power source which is connected to the high frequency generating electrode; a first heater element which is configured with a plurality of main heaters which are provided in a layer between the high frequency generating electrode and the temperature controlling base part; and a guard electrode which is provided in a layer between the high frequency generating electrode and the first heater element.
