Abstract
Provided is a solid-state imaging device including a first substrate that performs photoelectric conversion and a second substrate that reads photoelectric-converted photocurrent, the first substrate and the second substrate being stacked. The first substrate includes a photoelectric conversion part, a first insulating film that is disposed closer to the second substrate than the photoelectric conversion part and accumulates and transfers charge photoelectric-converted by the photoelectric conversion part, a first electrode disposed closer to the second substrate than the first insulating film and disposed facing the photoelectric conversion part, a second electrode disposed closer to the second substrate than the first insulating film and disposed apart from the first electrode, and an impurity ion diffusion region disposed facing the second electrode and disposed in a depth direction of the photoelectric conversion part from an interface between the photoelectric conversion part and the first insulating film.
