摘要:
A wafer has a rare earth fluoride coating disposed, typically sprayed on a substrate as an outermost layer, the rare earth fluoride being selected from lanthanoid fluorides, yttrium fluoride, and scandium fluoride. It is useful as a dummy wafer in a plasma etching or deposition system.
摘要:
A coated member comprising a substrate of Mo, Ta, W, Zr or carbon and a coating of rare earth-containing oxide including a surface layer having a Vickers hardness of at least 50; or a coated member comprising a substrate having a coefficient of linear expansion of at least 4×10−6 (1/K) and a coating of rare earth-containing oxide thereon is heat resistant and useful as a jig for use in the sintering of powder metallurgical metal, cermet and ceramic materials.
