Abstract: A solid-state image sensor includes pixel cells each of which is formed in and above a semiconductor substrate and that are arranged in each of a first direction and a second direction intersecting the first direction to form a two-dimensional array. The pixel cells include a first pixel cell and a second pixel cell arranged in the second direction, and the pixel circuit of the first pixel cell and the pixel circuit of the second pixel cell are adjacent to each other in the second direction between the photodetection portion of the first pixel cell and the photodetection portion of the second pixel cell. Each of the first transistors of the first pixel cell shares a gate electrode with the first transistor of the second pixel cell that has the same function as the first transistor of the first pixel cell.

Abstract: A plurality of pixel cells are provided on a semiconductor substrate and arranged in a two-dimensional array. At least one of the plurality of pixel cells includes a light receiving part, a pixel circuit, and a second transistor. The light receiving part receives an incident light to generate an electrical charge. The pixel circuit includes first transistors arranged side by side along a first direction and a charge retention part that retains the electrical charge generated by the light receiving part. The pixel circuit outputs a light receiving signal in accordance with the electrical charge generated by the light receiving part. The second transistor connects the charge retention part to a memory part that stores the electrical charge. Seen along a thickness direction of the semiconductor substrate, the second transistor is apart from the first transistors in a second direction orthogonal to the first direction.
