Patent ID: 7164447

Claim:
An AE/AF sensor device comprising: a first semiconductor region of a first conductivity type; a second semiconductor region of a second conductivity type opposite to the first conductivity type, said second semiconductor region being disposed in said first semiconductor region; a third semiconductor region of the second conductivity type formed in said first semiconductor region, said third semiconductor region being electrically isolated from said second semiconductor region; a fourth semiconductor region of the first conductivity type formed in said second semiconductor region; and a fifth semiconductor region of the first conductivity type formed in said third semiconductor region, wherein one photoelectric conversion element is formed by using said second and fourth semiconductor regions, and another photoelectric conversion element is formed by using said third and fifth semiconductor regions, wherein said one photoelectric conversion element is a photometry photoelectric conversion element, and said another photoelectric conversion element is an automatic focusing photoelectric conversion element, and wherein a dummy wiring region is disposed in a region other than the region where the photometry photoelectric conversion element and the automatic focusing photoelectric conversion element are formed so that a distance between wiring layers is set to 200 μm or shorter.
