摘要:
Embodiments of the present invention provide a substrate support assembly having a protective layer that enhances plasma resistance. In one embodiment, a substrate support assembly includes an electrostatic chuck having an upper substrate support surface, and a protective layer disposed on the electrostatic chuck, wherein the protective layer is fabricated by a ceramic material containing a rare earth metal.
摘要:
Method of removing damaged silicon carbide crystalline structure from the surface of a silicon carbide component. The method comprises at least two liquid chemical treatment processes, where one treatment converts silicon carbide to silicon oxide, and another treatment removes silicon oxide. The liquid chemical treatments are typically carried out at a temperature below about 100° C. The time period required to carry out the method is generally less than about 100 hours.
