Abstract:
An electrically conductive, plasma-resistant member adapted for exposure to a halogen-based gas plasma atmosphere includes a substrate having formed on at least part of a region thereof to be exposed to the plasma a thermal spray coating composed of yttrium metal or yttrium metal in admixture with yttrium oxide and/or yttrium fluoride so as to confer electrical conductivity. Because the member is conductive and has an improved erosion resistance to halogen-based corrosive gases or plasmas thereof, particle contamination due to plasma etching when used in semiconductor manufacturing equipment or flat panel display manufacturing equipment can be suppressed.
