Electrostatic chuck member and a method of producing the same
摘要:
An electrostatic chuck member comprises a metal substrate, an undercoat of a metallic spray-coated layer and a topcoat of Al 2 O 3 ·TiO 2 based spray-coated layer containing a Ti n O 2n-1 (n=1-9) type compound, and has a large volume resistivity and a less scattering thereof and a stable quality.
