Abstract:
Electrostatic chucks (ESCs) for plasma processing chambers, and methods of fabricating ESCs, are described. In an example, a substrate support assembly includes a ceramic bottom plate having heater elements therein. The substrate support assembly also includes a ceramic top plate having an electrode therein. A metal layer is between the ceramic top plate and the ceramic bottom plate.
