摘要:
A photoelectric conversion apparatus includes a plurality of photoelectric conversion elements configured to convert incident light to electric carriers, an amplifier MOS transistor shared by the plurality of photoelectric conversion elements, a plurality of floating diffusions connected to the gate electrode of the amplifier MOS transistor, and a plurality of transfer MOS transistors arranged corresponding to the respective photoelectric conversion elements, each of the transfer MOS transistors transferring electric carriers from corresponding one of the photoelectric conversion elements to corresponding one of the floating diffusions. In such a photoelectric conversion apparatus, at least two of the floating diffusions are electrically connected to each other with a wiring line included in the same wiring layer as the gate electrode of the amplifier MOS transistor.
