Patent number: 6328865Abstract: There is disclosed a method and apparatus for forming a thin film of a composite metal compound. Independent targets formed of at least two different metals are sputtered so as to form on a substrate an ultra-thin film of a composite metal or an incompletely-reacted composite metal. The ultra-thin film is irradiated with the electrically neutral, activated species of a reactive gas so as to convert the composite metal or the incompletely-reacted composite metal to a composite metal compound through the reaction of the ultra-thin film with the activated species of the reactive gas. The formation of the ultra-thin film and the conversion to the composite metal compound are sequentially repeated so as to form on the substrate a thin film of the composite metal compound having a desired thickness.Type: GrantFiled: December 7, 2000Date of Patent: December 11, 2001Assignee: Shincron Co., Ltd.Inventors: Shigeharu Matsumoto, Kazuo Kikuchi, Masafumi Yamasaki, Qi Tang, Shigetaro Ogura

Patent number: 5052033Abstract: A reflection type mask usable to print a pattern upon a semiconductor wafer by use of soft X-rays or otherwise is disclosed. A reflective surface is formed by a multilayered film which is formed on a substrate by layering different materials having different refractive indices in consideration of Bragg diffraction and Fresnel reflection. A non-reflective portion is formed on the reflecting surface to provide a desired pattern. Alternatively, a pattern comprising a multilayered structure may be formed upon a non-reflective substrate. The mask of the present invention assures pattern printing of high contrast.Type: GrantFiled: December 28, 1990Date of Patent: September 24, 1991Assignee: Canon Kabushiki KaishaInventors: Tsutomu Ikeda, Yutaka Watanabe, Masayuki Suzuki, Masami Hayashida, Yasuaki Fukuda, Shigetaro Ogura, Takashi Iizuka, Masahito Niibe

Patent number: 4531138Abstract: A liquid jet recording method and apparatus for recording information on a recording medium. A laser beam is irradiated onto an opto-mechanical transducer provided at a position, in a liquid flow path having at its distal end a discharge orifice for ejecting liquid in a predetermined direction and a pressure acting zone, at which a pressure acts on the recording liquid filled in that portion of the flow path, where the pressure as generated is effectively transmitted to the recording liquid filled in the pressure acting zone. This enables the liquid to be ejected from the discharge orifice, by which laser beam irradiation mechanical displacement is caused to deform the wall of the pressure acting zone to thereby bring about abrupt pressure change in the liquid filled in the pressure acting zone to eject the liquid from the discharge orifice in the form of droplets which fly toward the surface of a recording medium, on which the droplets adhere to make a necessary recording.Type: GrantFiled: December 16, 1983Date of Patent: July 23, 1985Assignee: Canon Kabushiki KaishaInventors: Ichiro Endo, Shigetaro Ogura, Shigeru Ohno
