Electrostatic chucking device

Abstract

Provided is an electrostatic chucking device having high heat resistance. The electrostatic chucking device of the present invention includes a first ceramic plate which includes a first surface on which a substrate is able to be placed and a second surface on the opposite side thereof, and in which an internal electrode for electrostatic adsorption is embedded; a heating member fixed to the second surface; a second ceramic plate adhered to the first ceramic plate and the heating member via a first adhesive layer; and a cooling base portion adhered to the second ceramic plate via a second adhesive layer and cools at least the second ceramic plate. The first adhesive layer has a higher heat resistance than the second adhesive layer. The second adhesive layer has a smaller Young's modulus than the first adhesive layer.
