Patent ID: 8664032

Claim:
A method of producing a solid-state image sensor, comprising the steps of: forming a first conductive type semiconductor layer, a first conductive type pillar-shaped semiconductor layer on the first conductive type semiconductor layer, a second conductive type photoelectric conversion region on the top of the first conductive type pillar-shaped semiconductor layer, and a high-concentrated impurity region of the first conductive type on a surface of the second conductive type photoelectric conversion region, the impurity region being spaced apart from a top end of the first conductive type pillar-shaped semiconductor layer by a predetermined distance; forming a second conductive type CCD channel region on a surface of the first conductive type semiconductor layer; forming a gate insulating film on the side of the first conductive type pillar-shaped semiconductor layer; and forming a transfer electrode on the side of the first conductive type pillar-shaped semiconductor layer via the gate insulating film, above the second conductive type CCD channel region.
