Abstract:
1. A metal film production method involving converting an atmosphere within a chamber into a plasma by supply of power from an antenna member, comprising: disposing an etched member made of a metal and having a plurality of segments which are arranged in a discontinuous state relative to a flowing direction of electricity in the antenna member; supplying a source gas containing a halogen into the chamber, said chamber accommodating a substrate supported by a platform; supplying power to the antenna member to generate on a substrate side of the etched member a flow of electricity in the same direction as the flowing direction of electricity in the antenna member, thereby converting the atmosphere within the chamber into a plasma and generating a source gas plasma so that the etched member is etched with the source gas plasma to form a precursor from a metal component contained in the etched member and the halogen; and controlling a temperature of the platform to a predetermined temperature, such that a temperature of the substrate is controlled to be about 100 to 200° C. to be lower than a temperature of the etched member to deposit the metal component of the precursor on the substrate as a film by a reduction reaction of the halogen.
