  • Publication number: 20190185986
    Abstract: 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.

  • Publication number: 20180354017
    Abstract: An inner circle and outer periphery punching step is performed in which a punching process is performed on a plate material made of a metal material to form an outline on an outer periphery side and a circle space on an inner periphery side, thereby forming an intermediate plate material. In an inner periphery bending step, the intermediate plate material is subjected to a bending process of bending a portion inside of a base circle that is a circle between an inner circle end portion and an outer circle, toward one side. In an inner periphery punching step, the intermediate plate material is subjected to a punching process of punching out inner periphery radial portions that are portions radially extending from the inner circle end portion, to form inner periphery slits extending inside of the outer circle in respective radial pieces.

  • Patent number: 9538964
    Abstract: An inclined PET device is provided in which the cut plane of a detector ring upon which a plurality of PET detectors are disposed is inclined so that it does not intersect perpendicularly with the long axis of a bed that carries a subject to be examined and in which an open space that passes through the bed in a direction perpendicular to the long axis thereof is formed, in order to enable access to the subject to be examined. The PET detectors are disposed and stacked in a direction parallel to the long axis of the bed. Thereby, the number of PET detectors is reduced and device cost is reduced, while the detector ring as well as the device can be miniaturized. At the same time, the open space that passes through the bed in a direction perpendicular to the long axis can be preserved.
