Publication number: 20240254616Abstract: There have been cases where transistors formed using oxide semiconductors are inferior in reliability to transistors formed using amorphous silicon. Thus, in the present invention, a semiconductor device including a highly reliable transistor formed using an oxide semiconductor is manufactured. An oxide semiconductor film is deposited by a sputtering method, using a sputtering target including an oxide semiconductor having crystallinity, and in which the direction of the c-axis of a crystal is parallel to a normal vector of the top surface of the oxide semiconductor. The target is formed by mixing raw materials so that its composition ratio can obtain a crystal structure.Type: ApplicationFiled: April 12, 2024Publication date: August 1, 2024Applicant: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Shunpei YAMAZAKI, Tetsunori MARUYAMA, Yuki IMOTO, Hitomi SATO, Masahiro WATANABE, Mitsuo MASHIYAMA, Kenichi OKAZAKI, Motoki NAKASHIMA, Takashi SHIMAZU

Patent number: 10704603Abstract: A cage assembly is moved in the axial direction to approach an inner ring from a small rib portion side. An inner ring assembly is constituted by causing tapered rollers of the cage assembly to climb over a small rib portion to be fitted on an inner raceway surface, and then is assembled to an outer ring. In this method, a jig is provided adjacent to the small rib portion. The jig includes recessed grooves that are formed in the outer peripheral portion of the jig and that enable contact of the respective tapered rollers. Each recessed groove has a recessed arcuate shape in cross section. The tapered rollers of the cage assembly are caused to slide radially outward along the recessed grooves, so that the diameter of cage is increased. Accordingly, the tapered rollers climb over the small rib portion to be fitted on the inner raceway surface.Type: GrantFiled: February 20, 2018Date of Patent: July 7, 2020Assignee: JTEKT CORPORATIONInventors: Masahiro Maruyama, Akiyuki Suzuki, Ryo Shiina
