  • Patent number: 8817164
    Abstract: An imaging device includes a basic cell having two or more the pixels that share floating diffusion. The imaging device also includes a transistor shared by the two or more pixels in the basic cell and arranged on the outside of the two or more pixels. The imaging device further includes a light receiving unit connected to the floating diffusion shared by the pixels in the basic cell through a transfer gate. In the imaging device, on-chip lenses are arranged substantially at regular intervals. Also, an optical waveguide is formed so that the position thereof in the surface of the solid-state imaging device is located at a position shifted from the center of the light receiving unit to the transistor and in the inside of the light receiving unit and the inside of the on-chip lens.
