Patent ID: 8735939

Claim:
A solid state imaging device comprising: a photoelectric converting portion, the photoelectric converting portion including a semiconductor region and a semiconductor film, the semiconductor region having a first region and a second region, the first region being of a second conductivity type, the first region being provided in a semiconductor substrate, the second region being of a first conductivity type, the first conductivity type being a different conductivity type from the second conductivity type, the second region being provided on the first region, the semiconductor film being of the second conductivity type, the semiconductor film being provided on the semiconductor region, wherein an absorption coefficient of a material of the semiconductor film to a visible light is higher than an absorption coefficient of a material of the semiconductor substrate to the visible light, a thickness of the semiconductor film is smaller than a thickness of the semiconductor region, and when seen through in a direction perpendicular to a surface of the semiconductor substrate, the semiconductor film is included within the second region.
