Abstract

A film-forming apparatus comprising a high-frequency application electrode and an earth electrode. The high-frequency applying electrode has an uneven surface with projections and recesses. An amorphous silicon film is formed uniformly on a substrate at a high speed by feeding a silicon-based gas into this apparatus and generating a glow discharge between the high-frequency application electrode and the earth electrode, and positioning the substrate in an atmosphere of the generated glow discharge.
