Abstract: A method for producing an electrostatic chuck includes the steps of (a) placing a ceramic slurry in a molding die, the ceramic slurry containing a ceramic powder, a solvent, a dispersing agent, and a gelling agent, gelatinizing the ceramic slurry in the molding die, and removing the molding die to obtain first and second ceramic molded bodies; (b) drying, debinding, and calcining the first and second molded bodies to obtain first and second ceramic calcined bodies; (c) printing an electrostatic electrode paste on a surface of one of the first and second ceramic calcined bodies to form an electrostatic electrode while assuming the first ceramic calcined body is to form a dielectric layer of an electrostatic chuck; and (d) superposing the first and second ceramic calcined bodies on each other to sandwich the electrostatic electrode and subjecting the first and second calcined bodies to hot-press firing.

Abstract: An electrostatic chuck and a base member are separated from each other while heating up a substrate mounting member to a thermal decomposition temperature within a range from a thermal decomposition starting temperature to a thermal decomposition ending temperature and then softening and decomposing an organic adhesive layer.

Abstract: An electrostatic adsorption device has a dielectric layer, electrodes, a cooling member and an insulating adhesive. The dielectric layer is made of a ceramic dielectric material and has an adsorption face and a back face. The electrodes are provided on the back face of the dielectric layer and gaps are defined between the portions of the electrodes. The insulating adhesive is provided between the back face of the dielectric layer and the cooling member. The insulating adhesive covers the electrodes and the back face and is provided in the gaps.
