Abstract: An electrostatic chuck includes a cooling plate having a cooling flow path, an insulating plate disposed on the cooling plate, an upper plate disposed on the insulating plate and fixed to the cooling plate, and a fastening member coupling the cooling plate to the upper plate. The fastening member passes through the cooling plate and is coupled to a fastening portion provided on a lower surface of the upper plate. Movement of the fastening member is constrained only in a first direction intersecting an upper surface of the upper plate.
