    Abstract: An electrostatic chuck device includes an electrostatic chuck member and a temperature controlling base member. The electrostatic chuck member has a ceramic plate having a mounting surface on which a plate-shaped sample is mounted, and an electrode for electrostatic attraction provided on the other surface on the side opposite the mounting surface of the ceramic plate. The temperature controlling base member is disposed on the surface on the side opposite the ceramic plate side of the electrode for electrostatic attraction and cools the electrostatic chuck member. The ceramic plate has a dike portion which extends to the temperature controlling base member side and surrounds the electrode for electrostatic attraction, the temperature controlling base member has a groove portion accommodating an end part of the dike portion, and a space between the groove portion and the dike portion is filled with a filling part formed of a resin material.

    Abstract: An electrostatic chuck part of an electrostatic chuck device has an electrostatic chuck part inner peripheral surface surrounding an opening of a chuck part through-hole, and an electrostatic chuck part outer peripheral surface surrounding the electrostatic chuck part inner peripheral surface. An insulator has an insulator main body in which an insulator through-hole having an opening on the electrostatic chuck part side is formed, an insulator inner end face, and an insulator outer end face which faces the electrostatic chuck part outer peripheral surface. The insulator inner end face and the electrostatic chuck part inner peripheral surface are in contact with each other, or an adhesion layer or a plasma-resistant adhesive layer extends in a gap between the insulator inner end face and the electrostatic chuck part inner peripheral surface. The plasma-resistant adhesive layer is formed between the electrostatic chuck part outer peripheral surface and the insulator outer end face.
