Abstract
An apparatus for plasma atomic layer deposition includes a tubular, insulating injector adhesion preventive member mountable to a gas-introducing opening section from inside a film forming chamber, a tubular, insulating exhaust adhesion preventive member mountable to an exhaust opening section from inside the film forming chamber, and an insulating film forming chamber adhesion preventive member mountable to an inner wall side of the film forming chamber. The injector adhesion preventive member and the exhaust adhesion preventive member are separated from each of a plate electrode and a counter electrode side, and the film forming chamber adhesion preventive member is disposed on each side of the injector adhesion preventive member and the exhaust adhesion preventive member to be separated from each of the plate electrode and the counter electrode side. The apparatus further includes an upper and lower inert-gas supply port that purges inert gas toward inside the film forming chamber.
