Patent ID: 8390713

Claim:
A photoelectric conversion device comprising: unit cells arranged in a well, each of the unit cells including a plurality of photoelectric conversion elements; an amplifier transistor; and a plurality of transfer transistors arranged between the plurality of photoelectric conversion elements and a gate electrode of the amplifier transistor, wherein each of the unit cells includes: a well-voltage-supply line configured to supply a voltage to the well; a well-contact part used to connect the well-voltage-supply line, wherein, in a region of the unit cell, the well-contact part is disposed between a first photoelectric conversion element of the plurality of photoelectric conversion elements and a second photoelectric conversion element of the plurality of photoelectric conversion elements, and the first photoelectric conversion element is adjacent to the second photoelectric conversion element; and plural transfer-control lines configured to control the plurality of transfer transistors, respectively, wherein, in a region of the unit cell, the plural transfer-control lines are symmetrically arranged with respect to the well-voltage-supply line.
