Abstract: PURPOSE:To prevent logging of a nozzle for introducing reactive gases and the formation of a film on parts exclusive of the part to be formed with the film at a plasma CVD device by specifically providing a gas cup and the above- mentioned nozzle and providing means for cooling a high-frequency electrode and gas cup. CONSTITUTION:A substrate holder 22 and the high-frequency electrode 23 are provided in parallel with each other in a vacuum chamber 21. The substrate 25 is fixed to the surface of the holder 22 and the holder 22 is heated by a heater 24. The gas cup 26 which encloses the space between the holder 22 and the electrode 23 together therewith is provided and the reactive gases are introduced to the above-mentioned space from the nozzle 27 provided in the side part of the electrode 23 to deposit the film on the substrate 25 surface. Since a discharge port 27a of the nozzle 27 is directed to the side wall of the cup 26 on the side opposite to the space where the plasma is formed and, therefore, the film is not formed in the discharge port 27a and the clogging thereof is obviated. Since the electrode 23 and the cup 26 are cooled by the cooling water supplied to water paths 30, 31, the film formation to the surfaces thereof is prevented and the film formation on the substrate 25 is well executed.
