Patent ID: 8399947

Claim:
A solid-state imaging device comprising: a plurality of photoelectric conversion units arranged in a matrix on a semiconductor substrate and each configured to convert an incident light into a signal charge; a plurality of vertical transfer units provided in each row of said photoelectric conversion units and each configured to transfer the signal charge read out from said photoelectric conversion unit in a vertical direction; a horizontal transfer unit configured to transfer the signal charge in a horizontal direction; a distribution transfer unit configured to selectively transfer the signal charge from said plurality of vertical transfer units to said horizontal transfer unit; and a plurality of first light-shield layers and second light-shield layers provided on said plurality of vertical transfer units and said distribution transfer unit and configured to block a light incident on said plurality of vertical transfer units; wherein said plurality of vertical transfer units each includes a plurality of vertical transfer electrodes, and is configured to transfer the signal charge in a vertical direction in accordance with a vertical transfer pulse applied to each of the plurality of vertical transfer electrodes; said distribution transfer unit includes a plurality of distribution transfer electrodes each corresponding to each of said vertical transfer units, and is configured to selectively transfer the signal charge in accordance with a distribution transfer pulse applied to each of the plurality of distribution transfer electrodes; said plurality of first light-shield layers and said second light-shield layers are conductive; said plurality of first light-shield layers is provided in a layer different from a layer in which said second light-shield layers are provided; at least one of said plurality of first light-shield layers serves as an interconnect electrically connected to the plurality of vertical transfer electrodes included in the same row; at least one of said plurality of first light-shield layers on said distribution transfer unit serves as an interconnect electrically connected the plurality of distribution transfer electrodes; and said plurality of first light-shield layers is disposed so as not to overlap with said horizontal transfer unit.
