Patent number: 6351367Abstract: There is disclosed an electrostatic holding apparatus in which a voltage is applied to an conductive electrode covered with an insulating dielectric layer in order to cause the insulating dielectric layer to electrostatically attract an object. The main component of the insulating dielectric layer is ceramic containing 0.1-30 wt. % of an atomic metal, and the volume resistivity of the metal-containing ceramic at 20° C. is 108-1013 &OHgr;·cm. The metallic element is Mo or W. In the electrostatic holding apparatus, since the volume resistivity of an insulating dielectric layer of an electrostatic attraction portion is decreased, a strong electrostatic force can be generated. Also, there can be maintained the capability of allowing removal of an object at the time of stopping application of voltage. Further, since neither fine cracks nor pores remain in the insulating dielectric layer after sintering, the withstand voltage is high.Type: GrantFiled: September 29, 1998Date of Patent: February 26, 2002Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Hiroshi Mogi, Yoshikazu Ohtani, Kenichi Arai, Shinji Kojima, Toshimi Kobayashi
