Abstract:
A film-forming apparatus comprising at least a vacuum chamber having a film-forming space provided therein, a high frequency power supply means, and a raw material gas introduction means and in which a non-single crystalline silicon series semiconductor film is formed on a substrate positioned in said film-forming space by introducing a raw material gas into said film-forming space through said raw material gas introduction means and supplying a high frequency power into said film-forming space through said high frequency power supply means, wherein said high frequency power supply means comprises a bar-like shaped electrode electrically connected to a very high frequency power source, said high frequency power supplied in said film-forming space comprises a very high frequency power, said bar-like shaped electrode is arranged such that the longitudinal direction of said bar-like shaped electrode intersects a direction for said substrate to be moved, and a length of said film-forming space relative to the direction for said substrate to be moved is in a range of from {fraction (1/16)} to Â½ of a wavelength of said very high frequency power supplied in said film-forming space.
