Abstract:
A member for a semiconductor manufacturing apparatus includes a ceramic plate; a composite plate joined to a lower surface of the ceramic plate; a cooling plate formed of a metal material, disposed on a lower surface of the composite plate; a first fastener that fastens the composite plate and the cooling plate; a support plate that is formed of an insulating material and supports a lower surface of the cooling plate; and a second fastener that fastens the cooling plate and the support plate, wherein, when the ceramic plate is heated from room temperature to high temperature, a first layered body including the ceramic plate and the composite plate deforms such that a central portion of the first layered body is convex, and a second layered body including the cooling plate and the support plate deforms such that a central portion of the second layered body is convex.
