Abstract:
1. A solid-state image pickup element comprising: a semiconductor substrate; a photoelectric converting film stacked above the semiconductor substrate; a plurality of photoelectric converting elements arranged in a row direction and a column direction perpendicular to the row direction on the semiconductor substrate, and accumulate signal charges; a plurality of signal charge accumulating portions in which signal charges generated in the photoelectric converting film are accumulated, the signal charge accumulating portions being arranged in the row direction and the column direction on the semiconductor substrate; and a signal read circuit which reads out to outside signals corresponding to signal charges accumulated in the photoelectric converting elements and the signal charge accumulating portions, the signal read circuit being formed in the semiconductor substrate, wherein the signal read circuit comprises: vertical transfer paths which read signal charges accumulated in the plural photoelectric converting elements and the signal charge accumulating portions, and which transfer the signal charges in the column direction; a horizontal transfer path which transfers signal charges transferred from the vertical transfer paths, in the row direction; and an output section which outputs color signals corresponding to the signal charges transferred from the horizontal transfer path, and wherein the vertical transfer paths are formed in such a manner that: two of the vertical transfer paths are present between first ones of said plurality of photoelectric converting elements, the first ones being adjacent to each other in the row direction; and two of the vertical transfer paths are present between second ones of said plurality of signal charge accumulating portions, the second ones being adjacent to each other in the row direction, the vertical transfer paths elongate in the column direction, the plurality of photoelectric converting elements comprises silicon, and the plurality of photoelectric converting elements and the plurality of signal charge accumulating portions are formed on a same plane of the substrate.
