More Information
Summary:The electrostatic chuck device includes: a base having one main surface serving as a mounting surface on which a plate-shaped sample is mounted; and an electrode for electrostatic attraction provided on a side opposite to the mounting surface in the base or in an interior of the base, in which the electrode for electrostatic attraction is made of a composite sintered body that includes a matrix phase having insulation properties and a dispersed phase having a lower volume resistivity value than the matrix phase, in any cross section of the composite sintered body, a region of the dispersed phase, which is surrounded by the matrix phase and is independent, includes aggregated portions having a maximum Feret diameter of 30 μm or more, and one or more of the aggregated portions are present in a range of 2500 μm2 in any cross section of the sintered body.
