Abstract

A solid-state imaging device includes a photoelectric conversion unit that is formed on a semiconductor substrate, a reading unit that reads signal charges of the photoelectric conversion unit, a gate insulating film and an electrode disposed thereon that constitute the reading unit, a light shielding film that covers the electrode, and an antireflection film that is formed on the photoelectric conversion unit and is constituted by films of four or more layers. The film of the lower layer of the antireflection film is also used as a stopper film during patterning, and a gap between the end of the light shielding film and the semiconductor substrate which is defined by interposing a plurality of films of the lower layer of the antireflection film is set so as to be smaller than the thickness of the gate insulating film.
