Abstract: A difficulty has been given, that is, in a condition that an electrostatic chuck having an oxide layer as a dielectric layer is set in catalytic chemical vapor deposition apparatus, as a silicon thin film is repeatedly deposited on a workpiece held by the electrostatic chuck, adsorbing power of the electrostatic chuck is gradually decreased, and finally the chuck does not adsorb a substrate at all. Thus, a dielectric layer on a surface of the electrostatic chuck is covered with an insulating film containing silicon nitride or silicon oxide. Thus, since damage to a chuck surface can be prevented, the damage being due to hydrogen radicals generated during depositing the silicon film by the catalytic chemical vapor deposition apparatus, even if the silicon film is repeatedly deposited, power for adsorbing the substrate is not decreased, and consequently substrate temperature is stabilized during depositing the silicon film.
