  • Patent number: 11066739
    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: 20190253649
    Abstract: An image pickup element is configured to remove fixed pattern noise at a fixed density over time. The image pickup element includes an image pickup unit and a compensating unit. The image pickup unit converts light, received by light-receiving elements in unit pixels arranged in a matrix, into an electric charge to output electronic image data. The compensating unit subtracts and removes a noise pattern from the image data, while having a storage unit store the noise pattern of fixed pattern noise of the image data. The compensating unit reads data output and obtained during cutting in a vertical blanking interval of each frame. The compensating unit reads image data and reads the data obtained during cutting of all of the light-receiving elements in an image pickup area from at least one frame among frames listed in time series. The compensating unit averages the data obtained during cutting with the noise pattern, read from the storage unit, to update the noise pattern.
