Patent ID: 7557846

Claim:
A solid-state image sensor comprising a plurality of pixels arranged in a matrix in a row direction and in a column direction, each of said plurality of pixels including photoelectric converter; a first transistor for transferring a signal charge generated in the photoelectric converter; an impurity diffused region for storing the signal charge outputted from the photoelectric converter via the first transistor; a second transistor for outputting a signal, based on the signal charge stored in the impurity diffused region; a third transistor for resetting an input terminal of the second transistor; the second transistor of a first one of said pixels in an nth row, and the second transistor of a second one of said pixels in an n+1th row being made common, the third transistor of the first pixel and the first transistor of the second pixel being made common, the first transistor of the first pixel and the first transistor of the second pixel being formed in regions positioned respectively on the same side in the column direction with respect to the photoelectric converter of the first pixel and the photoelectric converter of the second pixel, and at least one of the second transistor made common and the third transistor made common being formed in a region positioned on a side in the row direction with respect to the photoelectric converter of the first pixel and the photoelectric converter of the second pixel, wherein the first transistor of the first pixel is formed at least in a region positioned between the photoelectric converter of the first pixel and the photoelectric converter of the second pixel, and the first transistor of the second pixel is formed at least in a region positioned between the photoelectric converter of the second pixel and the photoelectric converter of a third one of said pixels in an n+2th row.
