Patent ID: 7709870

Claim:
A solid-state image pickup device comprising: a semiconductor substrate including a substrate main body having P type impurities and a first N type semiconductor layer provided on the substrate main body; an image pickup area including a plurality of photoelectric converters in which said plurality of photoelectric converters include second N type semiconductor layers, the second N type semiconductor layers being provided on a surface portion of the first N type semiconductor layer independently of one another; a peripheral circuit logic area including a first P type semiconductor layer formed on the first N type semiconductor layer without reaching to the substrate main body, a first P-well for a N-type MOS transistor and a first N-well for a P-type MOS transistor being formed in a surface of the first P-type semiconductor layer; and a peripheral circuit analog area including a second P type semiconductor layer formed on the substrate main body to be electrically connected to the substrate main body, a second P-well for a N-type MOS transistor and a second N-well for a P-type MOS transistor being formed in a surface of the second P-type semiconductor layer.
