Claim Text:
1. A semiconductor device comprising: a first semiconductor wafer having a light incident side and including a pixel section, the pixel section including a photodiode and at least one of a transfer transistor, a reset transistor, or an amplification transistor; a second semiconductor wafer including a logic circuit, the logic circuit including a signal processing unit, wherein the first semiconductor wafer and the second semiconductor wafer are bonded to each other; a first multi-wiring layer formed at a side opposite to the light incident side of the first semiconductor wafer, wherein the first multi-wiring layer is connected to the pixel section; a second multi-wiring layer formed at a first side of the second semiconductor wafer, wherein the side opposite to the light incident side of the first semiconductor wafer and the first side of the second semiconductor wafer face each other; a connection conductor extending from the light incident side of the first semiconductor wafer to the second multi-wiring layer through the first semiconductor wafer in a peripheral section other than the pixel section; and an insulating layer disposed on a top surface of the connection conductor,
