Patent ID: 7157758

Claim:
A solid-state image sensing device comprising: a semiconductor area of a first conductivity type having a first well of a second conductivity type formed therein; a second well of the second conductivity type formed in the semiconductor area, the second well overlapping the first well in a lateral direction thereof at an end portion of the second well; a gate electrode disposed on the second well so as to cover the overlapping portion; a drain layer of the first conductivity type disposed on one side of the gate electrode; a source layer of the first conductivity type disposed on the other side of the gate electrode; a channel area disposed under the gate electrode, the channel area being located between the drain layer and the source layer; a carrier pocket of the second conductivity type disposed under the channel area, and in the second well of the second conductivity type; a semiconductor substrate of the second conductivity type on which the semiconductor area of the first conductivity type is located; an embedded layer of the first conductivity type disposed under the semiconductor area of the first conductivity type corresponding to a position of the first well; and an embedded layer of the second conductivity type disposed under the semiconductor area of the first conductivity type corresponding to a position of the second well and a region where the second well overlaps the first well.
