Patent number: 9903012Abstract: A film formation method is one for forming an organic layer comprising a fluorine-containing resin on an inorganic layer (3) formed on a substrate and comprising an inorganic substance. In the method, for the formation of the inorganic layer, a reactive sputtering procedure using water vapor as a reactive gas is carried out to form the inorganic layer on the substrate. Subsequently, the organic layer is formed on the inorganic layer. A film formation device enables the implementation of the film formation method.Type: GrantFiled: December 18, 2012Date of Patent: February 27, 2018Assignee: ULVAC, INC.Inventors: Takashi Yoshida, Masahiro Matsumoto, Noriaki Tani, Susumu Ikeda, Masashi Kubo

Publication number: 20140216332Abstract: Provided is a vacuum treatment device, when a lifting pin inserted to a through hole is moved up, a substrate on a placement table is placed on a lid member which is connected to an upper end of a lifting pin and is separated from a placement surface of the placement table. Additionally, when the lifting pin is moved down, the substrate comes into contact with the placement surface so as to be placed thereon. An annular seal member surrounding a periphery of an opening of the through hole is provided in a portion which faces the lid member in a bottom surface of a depression provided in the placement surface of the placement table. The lid member annularly comes into contact with the seal member when the lifting pin is moved down, and a space inside the through hole and a space outside the through hole are separate by the seal member, thereby preventing gas from flowing into the through hole.Type: ApplicationFiled: April 14, 2014Publication date: August 7, 2014Applicant: ULVAC, INC.Inventors: Miki OMORI, Harunori IWAI, Yuichi TACHINO, Masashi KUBO
