Abstract:
A solid-state imaging device includes a photoelectric conversion unit, a light shielding unit and a transfer transistor. The photoelectric conversion unit generates charges by photoelectrically converting light. The light shielding unit is formed by engraving a semiconductor substrate on which the photoelectric conversion unit is formed, so as to surround an outer periphery of the photoelectric conversion unit. The transfer transistor transfers charges generated in the photoelectric conversion unit. During a charge accumulation period in which charges are accumulated in the photoelectric conversion unit, a potential that repels the charges is supplied to the light shielding unit and a gate electrode of the transfer transistor. During a charge transfer period in which charges are transferred from the photoelectric conversion unit, a potential that repels the charges is supplied to the light shielding unit and a potential that attracts the charges is supplied to the gate electrode of the transfer transistor.

Claim (Index 15):
The imaging device according to  claim 1 , further comprising a wiring layer disposed at the second side of the semiconductor substrate.
