Title:
固体撮像装置及び撮像システム
Document Type and Number:
Japanese Patent JP6595750
Kind Code:
B2
Abstract:
A solid-state imaging device including a plurality of pixels including a photoelectric conversion portion, a charge holding portion accumulating a signal charge transferred from the photoelectric conversion portion, and a floating diffusion region to which the signal charge of the charge holding portion is transferred, wherein the photoelectric conversion portion includes a first semiconductor region of a first conductivity type, and a second semiconductor region of a second conductivity type formed under the first semiconductor region, the charge holding portion includes a third semiconductor region of the first conductivity type, and a fourth semiconductor region of the second conductivity type formed under the third semiconductor region, and a p-n junction between the third semiconductor region and the fourth semiconductor region is positioned deeper than a p-n junction between the first semiconductor region and the second semiconductor region.
