| 摘要 |
A method for forming a metal film, including bringing a raw material gas containing a halogen into contact with a hot metallic filament, thereby etching the filament with the raw material gas to produce a precursor composed of a metallic component contained in the filament and the halogen contained in the raw material gas, producing an atomic reducing gas by heating a reducing gas to a high temperature, passing the precursor through the atomic reducing gas to remove the halogen from the precursor, and directing the resulting metallic ion or neutral metal onto a substrate to form a thin metal film on the substrate.
