Patent ID: 7911521

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 photoelectric conversion elements and a gate electrode of the amplifier transistor, wherein each of the unit cells includes: a well-voltage-supply line used to supply a voltage to the well, a well-contact part that connects the well-voltage-supply line and the well, and plural transfer-control lines used to control the plurality of transfer transistors, wherein, in a region of each unit cell, the plural transfer-control lines are symmetrically arranged with respect to the well-voltage-supply line, wherein the well-voltage-supply line and the plural transfer-control lines are arranged to be parallel to one another, and wherein, in the region of each unit cell, the amplifier transistor is arranged in such a manner that a virtual line extends through the gate electrode of the amplifier transistor, the virtual line being parallel to the well-voltage-supply line and the plural transfer-control lines and extending through the well-contact part.
