Abstract:
Apparatus for depositing a thin film on a substrate surface, comprising:a process chamber; a substrate holder provided in said process chamber; a thermal catalysis body provided near said substrate holder; a heater for heating said thermal catalysis body as far as said substrate does not suffer thermal degradation; deposition gas introduction system for introducing a deposition gas into said process chamber; and treatment gas introduction system introducing a treatment gas, which is provided other than said deposition gas introduction system, wherein said thermal catalysis body is provided at a location between said substrate and both of said deposition gas introduction system and said treatment gas introduction system such that said thin film is deposited on said substrate surface utilizing reaction of said deposition gas supplied with said substrate surface via said thermal catalysis body and a treatment for reducing interfacial defects between said substrate surface and said thin film is carried out by supplying said treatment gas with said substrate via said thermal catalysis body in said chamber before said thin film deposition.
