Patent ID: 8273409

Claim:
A method for forming a metal film on the surface of a substrate to be processed comprising: providing a process gas supply unit including a process gas introducing unit and a process gas blocking unit in an upper side of a substrate holding plate provided in a processing chamber to hold the substrate, where, when viewed from a vertical direction, the process gas introducing unit is positioned at an upper-outer side of the substrate than the periphery of the substrate and the process gas blocking unit is positioned at an upper side of the substrate; supplying the process as including a raw gas containing a metal carbonyl and a carrier gas containing carbon monoxide into the processing chamber through the process gas introducing unit, thereby supplying the process gas substantially to the region of an upper-outer side of the substrate than the periphery of the substrate; and diffusing the metal carbonyl to the surface of the substrate from the flow of the process gas thereby depositing the metal film on the surface of the substrate.
