Patent ID: 8624307

Claim:
A solid-state imaging device of a pixel amplifying type, comprising a plurality of pixels, wherein each pixel includes: a photoelectric conversion unit including a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type opposite to the first conductivity type; and an amplifying transistor of the first conductivity type, wherein the solid-state imaging device further comprises: an element isolation region configured to electrically isolate the first semiconductor region from a peripheral element; a third semiconductor region of the second conductivity type arranged along a lower surface of the element isolation region; and a fourth semiconductor region of the second conductivity type arranged so as to partially overlap with the third semiconductor region in a planar view, wherein the third semiconductor region is arranged so as not to overlap with a source or a drain of the amplifying transistor in the planar view, and the fourth semiconductor region is arranged so as to partially overlap with the source or the drain of the amplifying transistor in the planar view.
