  • Publication number: 20240254616
    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.

  • Patent number: 8841664
    Abstract: Provided is a highly reliable semiconductor device by giving stable electric characteristics to a transistor in which a semiconductor film whose threshold voltage is difficult to control is used as an active layer. By using a silicon oxide film having a negative fixed charge as a film in contact with the active layer of the transistor or a film in the vicinity of the active layer, a negative electric field is always applied to the active layer due to the negative fixed charge and the threshold voltage of the transistor can be shifted in the positive direction. Thus, the highly reliable semiconductor device can be manufactured by giving stable electric characteristics to the transistor.
