Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate; a plurality of photoelectric conversion layers comprising three photoelectric conversion layers stacked above the semiconductor substrate, each detecting a different color from the others of the three photoelectric conversion layers, a plurality of signal charge accumulators comprising three signal charge accumulators in the semiconductor substrate, each accumulating signal charges generated in a corresponding layer of the three photoelectric conversion layers; and a signal readout circuit in the semiconductor substrate, the signal readout circuit reading out signals corresponding to the signal charges accumulated in the three signal charge accumulators, wherein a plurality of pixels is arranged in a square lattice pattern on a surface of the semiconductor substrate, the square lattice pattern extending in a column direction and a row direction perpendicular to the column direction, the column and row direction being parallel to the surface of the semiconductor substrate, and each of the pixels comprising the three signal charge accumulators which are arranged in the column direction on the surface of the semiconductor substrate, wherein an arrangement of the pixels is such that the square lattice pattern of the pixels includes a first pixel row comprising: wherein the three signal charge accumulators are arranged such that each of the first, second and third arrays includes all of the three signal charge accumulators, and wherein the three signal charge accumulators are provided apart from the three photoelectric conversion layers and are electrically connected to the three photoelectric conversion layers via respective wirings, and the signal charges accumulating in the three signal charge accumulators are transferred through the respective wirings from the three photoelectric conversion layers.
