Patent ID: 7456888

Claim:
A photoelectric conversion device comprising: a plurality of photoelectric conversion regions, each photoelectric conversion region having a first semiconductor region for accumulating electric charges that correspond to incident light; a plurality of electrodes, each electrode being arranged at a side of a corresponding first semiconductor region for transferring a signal charge from said first semiconductor region; and a plurality of amplifying field effect transistors, each field effect transistor receiving a signal charge from a corresponding photoelectric conversion region inputted by a corresponding electrode, wherein: each first semiconductor region is surrounded by a potential barrier region that includes at least an oxidized film for isolation, a channel stopping layer directly below said oxidized film, and a buried isolation region whose conductivity type is opposite to said conductivity type of said first semiconductor region below said channel stopping layer, for each potential barrier region, a nick region is formed in a part of said potential barrier region and is arranged at a side different from a side at which a corresponding electrode is arranged, such that said potential barrier region does not include a buried isolation region at said part in which said nick region is formed, and a source or drain region of each field effect transistor is placed adjacent to a corresponding nick region, said source or drain region having a same conductivity type as a conductivity type of said first semiconductor regions.
