Abstract
An image sensor has a gate that is electrically connected to a wiring layer and is formed at a side that overlaps a photodiode or storage diode in a semiconductor layer, so that an electrical charge can be easily transferred to a floating diode. The image sensor comprises: a semiconductor layer having a front surface and a back surface; a photodiode and a floating diode disposed apart from each other in the semiconductor layer; a first gate disposed on the front surface of the semiconductor layer and in an insulating layer; a second gate disposed on the front surface of the semiconductor layer and in the insulating layer, the second gate being configured to serve as a transfer transistor; the insulating layer disposed on the front surface of the semiconductor layer; and a wiring layer disposed in the insulating layer.
