Abstract:
1. A solid-state imaging device comprising: a plurality of photoelectric conversion elements disposed on an imaging surface of a substrate, each of the photoelectric conversion elements receiving light incident on a light receiving surface and performing photoelectric conversion to produce a signal charge; a plurality of electrodes interposed between the photoelectric conversion elements arranged on the imaging surface of the substrate; and a plurality of light blocking portions provided above the plurality of electrodes and interposed between the photoelectric conversion elements arranged on the imaging surface of the substrate, wherein each of the light blocking portions includes an electrode light blocking portion formed to cover the corresponding electrode, and a pixel isolation and light blocking portion protruding convexly from the upper surface of the electrode light blocking portion, the plurality of photoelectric conversion elements are arranged at first pitches on the imaging surface, the electrode light blocking portions in the plurality of light blocking portions are arranged at second pitches on the imaging surface, the pixel isolation and light blocking portions in the plurality of light blocking portions are arranged at third pitches on the imaging surface, and at least the third pitch increases with distance from the center toward the periphery of the imaging surface.
