Abstract:
A solid state image sensor unit which includes a substrate having a substrate surface and a plurality of first semiconductor regions formed on said substrate surface along a predetermined direction of said substrate surface with said first semiconductor regions substantially isolated electrically from each other, wherein comprising:a connection member formed on said substrate surface for supplying a reference potential to said first semiconductor regions in common; anda central unit section, formed on a central area of said substrate surface, to perform photoelectric conversion and charge transfer and a peripheral unit section, formed on a peripheral area of said substrate surface, to mainly perform charge detection;said first semiconductor regions being formed in said central unit section;said central unit section comprising a plurality of vertical charge transfer portions formed between each of said first semiconductor regions and extended along a vertical direction vertical to said predetermined direction and a pair of horizontal charge transfer portions formed at both ends of each of said vertical charge transfer portions and extended along a horizontal direction parallel to said predetermined direction;said peripheral unit section comprising a second semiconductor region formed along said peripheral area, said second semiconductor region being supplied with said reference potential;said first semiconductor regions being substantially isolated electrically from said second semiconductor region by said horizontal charge transfer portions and one of said vertical charge transfer portions;said connection member electrically connecting said first semiconductor regions and said second semiconductor to each other.
