Abstract:
An electrostatic chuck and a manufacturing method are disclosed in which drawbacks of using an adhesive are not existent and a freedom degree of design is high. The electrostatic chuck includes a substrate part constituting a main chuck body, a first insulating layer of a spray coating formed to the surface of the substrate part, a heater part of an electric conductor formed by applying a conductive paste to the surface of the first insulating layer, a second insulating layer of a spray coating formed to the surface of the first insulating layer so as to cover the heater part, an electrode part formed by thermal spraying to the surface of the second insulating layer and a dielectric layer of a spray coating formed to the surface of the second layer so as to cover the electrode part and lowers a volume resistivity without using an adhesive.
