Patent ID: 8415604

Claim:
A solid-state imaging device comprising: a plurality of photoelectric converting portions, each having a photosensitive region which generates a charge according to incidence of light and which has a planar shape of a nearly rectangular shape composed of two long sides and two short sides, and a potential gradient forming region which forms a potential gradient increasing along a first direction directed from one short side to the other short side forming the planar shape of the photosensitive region, in the photosensitive region, said plurality of photoelectric converting portions being juxtaposed along a second direction intersecting with the first direction; a plurality of first transferring portions arranged corresponding to the respective photoelectric converting portions and on the side of the other short side fanning the planar shape of the photosensitive region, each first transferring portion transferring a charge acquired from the photosensitive region of the corresponding photoelectric converting portion, in the first direction; a plurality of charge accumulating portions arranged corresponding to the respective first transferring portions, each charge accumulating portion accumulating a charge transferred from the corresponding first transferring portion; a plurality of second transferring portions arranged corresponding to the respective charge accumulating portions, each second transferring portion transferring a charge accumulated in the corresponding charge accumulating portion, in the first direction; and a charge output portion arranged to the plurality of second transferring portions, said charge output portion transferring and outputting charges transferred from the respective second transferring portions, in the second direction.
