Patent ID: 8552481

Claim:
An imaging device comprising a plurality of pixels, wherein each of the plurality of pixels includes a photoelectric conversion region, a transfer MOS transistor and a floating diffusion region, the transfer MOS transistor including a channel region and a gate electrode provided on the channel region, wherein the plurality of pixels includes a first pixel and a second pixel, the photoelectric conversion region of the first pixel and the photoelectric conversion region of the second pixel being arranged along a first direction, wherein the photoelectric conversion region, the channel region of the transfer MOS transistor and the floating diffusion region of the first pixel are arranged in translational symmetry with respect to the photoelectric conversion region, the channel region of the transfer MOS transistor and the floating diffusion region of the second pixel, wherein the floating diffusion region of the first pixel is electrically connected to the floating diffusion region of the second pixel, wherein a part of the gate electrode of the transfer MOS transistor of the first pixel is provided on a region between the photoelectric conversion region of the first pixel and the photoelectric conversion region of the second pixel, and wherein the photoelectric conversion region of the first pixel and the floating diffusion region of the first pixel are arranged along a second direction crossing the first direction.
