Abstract
A solid-state imaging device includes: multiple pixels. Each pixel is arranged at a surface layer portion of a semiconductor substrate, and includes: a photoelectric conversion portion that converts light incident into an electric charge; a charge holding portion that stores the electric charge, and is arranged in the semiconductor substrate; a multiplication gate electrode that is capacitively coupled with the charge holding portion, and is arranged on the semiconductor substrate via an insulation film; and a charge barrier portion that is arranged between the charge holding portion and the insulation film, and has a higher impurity concentration than the semiconductor substrate.
