Patent ID: 8026469

Claim:
A photoelectric conversion device comprising a plurality of pixels, each pixel including a photoelectric conversion element, a source follower MOS transistor whose gate is directly connected to the photoelectric conversion element, and a reset MOS transistor for resetting a signal of the photoelectric conversion element, wherein the photoelectric conversion device includes a first pixel column including a first plurality of pixels and a second pixel column including a second plurality of pixels, an alignment direction of the second plurality of pixels being parallel to an alignment direction of the first plurality of pixels, wherein the reset MOS transistor and the source follower MOS transistor of one of the second plurality of pixels are arranged in a region between a region where a photoelectric conversion element of the first pixel column is arranged and a region where a photoelectric conversion element of the second pixel column is arranged, wherein a conductive pattern that connects the photoelectric conversion element of a pixel with the gate of the source follower MOS transistor thereof is arranged in the region between the region where the photoelectric conversion element of the first pixel column is arranged and the region where the photoelectric conversion element of the second pixel column is arranged, wherein a plurality of readout wirings are provided as electric paths between output nodes of the source follower MOS transistors and a readout circuit provided for the output nodes, the readout wirings being separated from each other in a region between the output nodes and the readout circuit, and wherein a part of a conductive pattern of a readout wiring of a pixel included in the second pixel column is provided between photoelectric conversion elements of adjacent pixels of the first pixel column.
