Publication number: 20090057144Abstract: An arc evaporation source and a vacuum deposition system capable of properly collecting an evaporated material emitted from a cathode in vacuum arc discharge are provided. An arc evaporation source (100) includes a first electrode and a second electrode (14A, 14B) disposed so as to face each other with a gap (G) therebetween. The first and second electrodes (14A, 14B) are configured such that at least one of the first and second electrodes (14A, 14B) is operable as a cathode, and the other one of the first and second electrodes (14A, 14B) is operable to collect an evaporated material emitted from the cathode, based on a vacuum arc discharge occurring between the cathode and an anode.Type: ApplicationFiled: June 22, 2006Publication date: March 5, 2009Applicant: Shinmaywa Industries, Ltd.Inventors: Yasuhiro Koizumi, Kouichi Nose

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
