Abstract:
The present disclosure provides an electrostatic chuck device capable of uniformly cooling or heating a fixedly adsorbed substrate. The electrostatic chuck device includes an electrostatic chuck plate, a bonding layer, and a base. The bonding layer has a bonding agent bonded to a rear surface of the electrostatic chuck plate. The base has a bonding surface bonded to the bonding layer and a plurality of protrusions radially extending from a central part toward an outer circumferential surface of the bonding surface. The ends of the respective protrusions on the central part may be arranged at intervals.
