Patent ID: 8633559

Claim:
A solid-state imaging device comprising: light-sensing sections serving as pixels; waveguides each including a core layer and a cladding layer, each of the waveguides being disposed at a position corresponding to one of the light-sensing sections; a vertical transfer register section disposed for each column of light-sensing sections; transfer electrodes composed of first-layer polysilicon disposed in the vertical transfer register section; and connecting conductive layers composed of second-layer polysilicon, the connecting conductive layers being connected to predetermined transfer electrodes among the transfer electrodes; wherein, the transfer electrodes other than the predetermined transfer electrodes and portions of the connecting conductive layers lying as an upper layer extend between the vertically adjacent pixels, a cross-sectional structure including the transfer electrodes and the connecting conductive layers in the vertical transfer register section is different from a cross-sectional structure including the transfer electrodes and the connecting conductive layers extending between the vertically adjacent pixels, and a cross-sectional structure of the waveguide taken in a direction parallel to a direction of pixel arrangement period is different from a cross-sectional structure of the waveguide taken in a direction orthogonal to the direction of pixel arrangement period with pixel arrangements being different in a horizontal direction of an imaging plane and in a vertical direction of the imaging plane.
