Patent ID: 8624306

Claim:
A solid-state imaging device comprising: a substrate; a photoelectric conversion unit in the substrate and that generates signal charges in accordance with the amount of received light; a through-hole extending through the substrate from a front surface side of the substrate to a rear surface side of the substrate; a vertical gate electrode in the through-hole; a gate insulating film between the vertical gate electrode and an inner circumferential surface of the through-hole, the vertical gate electrode allowing a reading-out portion to read out the signal charges generated by the photoelectric conversion unit when a potential is applied to the vertical gate electrode; and a charge fixing film with negative fixed charges covering the rear surface side of the substrate and a portion of the inner circumferential surface of the through-hole at the rear surface side of the substrate so as to be between an end portion of the vertical gate electrode and the portion of the inner circumferential surface of the through-hole at the rear surface side of the substrate.
