Patent ID: 8823125

Claim:
A solid-state image pickup device including a plurality of pixels, each of the plurality of pixels comprising: a photoelectric conversion portion configured to generate charges in accordance with incident light; a charge holding portion configured to include a first-conductivity-type first semiconductor region that holds the charges generated by the photoelectric conversion portion in a portion different from the photoelectric conversion portion; and a transfer portion configured to include a transfer gate electrode that controls a potential between the charge holding portion and a sense node, wherein the charge holding portion includes a control electrode that is disposed above the first semiconductor region via an insulating film, wherein a second-conductivity-type second semiconductor region is disposed on a surface of a semiconductor region between the control electrode and the transfer gate electrode, wherein a first-conductivity-type third semiconductor region is disposed under the second semiconductor region, at a position of a charge path extending from the charge holding portion to the sense node, wherein a second-conductivity-type well is disposed under the third semiconductor region, and wherein the third semiconductor region is disposed at a deeper position than the first semiconductor region.
