Abstract:
A solid-state image sensor includes first and second pixels formed on a semiconductor substrate. The first pixel includes: a first photoelectric conversion region located in an upper portion of the semiconductor substrate; a first transfer electrode; a light-shield film covering the first transfer electrode and having a first opening on the first photoelectric conversion region; and a first anti-reflection film located on the first photoelectric conversion region and, when viewed in plan, within the first opening so as not to overlap the first light-shield film. The second pixel includes: a second photoelectric conversion region located in an upper portion of the semiconductor substrate; a second transfer electrode; the light-shield film covering the second transfer electrode and having a second opening on the second photoelectric conversion region; and a second anti-reflection film located on the second photoelectric conversion region and continuously extending to a portion on the second transfer electrode.
