SEMICONDUCTOR PROCESSING APPARATUS WITH A CERAMIC-COMPRISING SURFACE WHICH EXHIBITS FRACTURE TOUGHNESS AND HALOGEN PLASMA RESISTANCE
摘要:
A solid solution-comprising ceramic article useful in semiconductor processing, which article may be in the form of a solid, bulk ceramic, or may be in the form of a substrate having a ceramic coating of the same composition as the bulk ceramic material on at least one outer surface. The ceramic article is resistant to erosion by halogen-containing plasmas and provides advantageous mechanical properties. The solid solution-comprising ceramic article is formed from a combination of yttrium oxide and zirconium oxide. The ceramic-comprising article includes ceramic which is formed from zirconium oxide at a molar concentration ranging from about 96 mole % to about 91 mole %, and yttrium oxide at a molar concentration ranging from about 4 mole % to about 9 mole %.
