Patent ID: 8471314

Claim:
A solid-state imaging device comprising: a substrate having a first surface and a second surface, light being incident on the second surface side; a wiring layer disposed on the first surface side; a photodetector formed in the substrate, the photodector including an n-type charge-accumulation region and a p-type hole-accumulation region that is disposed on the first surface side; a transfer gate of a transfer transistor disposed on the first surface of the substrate and adjacent to the photodetector, the transfer gate transferring a signal charge accumulated in the photodetector; and a control gate disposed on the first surface of the substrate and provided separately from the transfer gate of the transfer transistor to control a potential of the photodetector in a vicinity of the first surface of the substrate, the control gate being disposed such that the control gate only partially overlaps the photodetector along a direction parallel to the first surface of the substrate, and the p-type hole-accumulation region being disposed at least in a part of the photodector that is not overlapped by the control gate.
