Abstract:
A method of forming a semiconductor thin film by a plasma CVD process, which comprises introducing into a film forming chamber a source gas through a source gas introducing portion and a high-frequency power through a high-frequency power introducing electrode to generate a plasma in the film forming chamber, thereby forming the semiconductor thin film on a substrate arranged in the film forming chamber, wherein the frequency of the high-frequency power is within a range of 50 to 2000 MHz; the input power density of the high-frequency power is within a range of 0.001 to 1.0 W/cm.sup.3 ; the forming pressure is within a range of 0.005 to 0.5 Torr; and the temperature of the substrate is within a range of 150 to 500 .degree. C., and wherein a metal mesh having an aperture percentage within a range of from 30 to 95% and the aperture portion lengths are in a range of 5 to 30 mm is disposed so as to surround the high-frequency power introducing electrode such that the plasma is substantially confined between the substrate and the source gas introducing portion, thereby forming the semiconductor thin film on the substrate.
