ABSTRACT:
An electrostatic chuck plate comprises an electrode plate made of electrically conductive material and a dielectric layer formed on one surface of the electrode plate by flame-spraying dielectric material. The surface region of the dielectric layer is impregnated with plastic material, and the surface of the dielectric layer is smooth and flat. A sample is electrostatically attracted toward the electrode plate and is thus held on the smooth and flat surface of the dielectric layer.
