Abstract
A semiconductor image sensor which comprises a plurality of image sensor cells, each having a photosensing and accumulation region of an n.sup.+ -p.sup.- -(i)-p.sup.+ -n.sup.+ (or p.sup.+ -n.sup.- -(i)-n.sup.+ -p.sup.+) hook structure which is formed by sequentially forming its respective regions in a semiconductor substrate inwardly thereof from its surface. The photosensing and accumulation regions are isolated by insulating isolation regions from adjacent ones of them. A tapering conductive region, which acts as an electric field lens on charged carriers, is formed to extend into a high resistivity layer of the photosensing region from the end face of each insulating isolation region on the side of the semiconductor substrate.
