  • Patent number: 8212366
    Abstract: Input/output cells are formed so as to be peripherally arranged adjacent to a corner cell on a surface of a semiconductor chip, and electrode pads are formed on the respective input/output cells. The electrode pads are configured in a zigzag pad arrangement so as to form inner and outer pad arrays. However, of the electrode pads forming the inner pad array, those electrode pads in predetermined areas adjacent to the two sides of the corner cell are not disposed, such that an interconnect pattern of a carrier which is bump-bonded to the semiconductor chip and vias are prevented from becoming complex.

  • Publication number: 20120069211
    Abstract: An image pickup apparatus is provided with: an optical system including a lens or a reflecting mirror; an image pickup device having a light-receiving surface on which light rays from the optical system are focused and a plurality of light-receiving pixels which generate charges on the light-receiving surface by the light rays; a bias voltage generation unit which supplies power to the image pickup device; a signal processing unit which processes a signal output from the image pickup device and outputs the processed signal as image data; and a control unit which inputs into the image pickup device a driving clock that controls transmission of the charges generated in the light-receiving pixels of the image pickup device. The image pickup device is bent so that distortion aberration present in the optical system is eliminated.
