发明名称 USE OF SINTERED NANOGRAINED YTTRIUM-BASED CERAMICS AS ETCH CHAMBER COMPONENTS
摘要 In accordance with this disclosure, there are provided several inventions, including an apparatus and method for creating a plasma resistant part, which may be formed of a sintered nanocrystalline ceramic material comprising yttrium, oxide, and fluoride. Example parts thus made may include windows, edge rings, or injectors. In one configuration, the parts may be yttria co-sintered with alumina, which may be transparent.
