There is disclosed a process for manufacturing a semiconductor device. When a metal film is formed by plasma CVD in a contact hole which penetrates an interlayer insulating film and reaches an electrode of the device, a gas comprising hydrogen and argon in a deposition chamber of a plasma CVD apparatus is introduced. Then a metal halide gas is introduced in the deposition chamber simultaneously with or before plasma generation.
