Substrate fixing device

Abstract

A substrate fixing device includes a base plate, a heat-generating part provided on the base plate via an adhesive layer, and an electrostatic chuck provided on the heat-generating part and configured to adsorb and hold a target object. The heat-generating part includes a first insulating layer having a first surface and a second surface opposite to the first surface, the first surface being in contact with the electrostatic chuck, a heat-generating element arranged on the second surface of the first insulating layer, and a second insulating layer stacked on the second surface of the first insulating layer and covering the heat-generating element. A through-hole penetrating through the base plate, the adhesive layer, and the second insulating layer and exposing a part of the heat-generating element is provided. A glass transition temperature of the second insulating layer is higher than a glass transition temperature of the first insulating layer.
