  • Solid-state imaging device having a light barrier layer
    Patent number: 5351081
    Abstract: A solid-state imaging device in which a light-barrier layer is formed on transfer electrodes on top of a vertical pixel isolating region by an insulating film. The light-barrier layer is adapted to overlie the lateral sides of the transfer electrodes and the peripheral region of a photosensor region neighboring on the vertical pixel isolating region. By provision of the light-barrier layer, the light incident on the vertical pixel isolating region is stopped to reduce smear charges which might otherwise be intruded into the vertical charge transfer section.
