Publication number: 20070039545Abstract: The present invention provides film formation systems and film formation methods. A high frequency (HF) electric power supply (11) applies a high frequency voltage to a cathode (5) which is provided, at its rear surface, with a permanent magnet (10), thereby to generate a reactive-mode plasma, and film formation by plasma polymerization is performed by the use of the generated reactive-mode plasma. The pressure of a plasma source gas in a vacuum chamber (1) is regulated, thereby to generate not a reactive-mode plasma but a metallic-mode plasma. The cathode (5) as a target is subjected to sputtering by the generated metallic-mode plasma, and film formation by magnetron sputtering is carried out.Type: ApplicationFiled: May 25, 2004Publication date: February 22, 2007Applicant: SHINMAYWA INDUSTRIES, LTDInventors: Kouichi Nose, Koichi Sasagawa, Takeshi Furutsuka, Shiro Takigawa, Yasuhiro Koizumi
