  • Patent number: 11959165
    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: 20230228792
    Abstract: A substrate (101) is etched by etching processing with crystal anisotropy, thereby forming a recess (104) from the main surface of the substrate (101) to the inside of the substrate (101). A side surface (105) is almost a (111) plane, and the etching hardly progresses. As a result, a cross section of the recess (104) perpendicular to the longitudinal direction has a rectangular shape. Since an opening (103) of a mask pattern (102) has a rectangular shape in a planar view, the opening of the recess (104) has a rectangular shape in a planar view, and the recess (104) is formed into, for example, a rectangular parallelepiped shape. The recess (104) includes a side surface (105) that forms one plane perpendicular to the main surface of the substrate (101). The side surface (105) is a facet surface and is a tilting surface tilted from the (111) plane.
