Abstract: An image sensor includes a semiconductor substrate, a first photoelectric converter, and a second photoelectric converter. The semiconductor substrate has an electric-charge storage region. The second photoelectric converter is located between the first photoelectric converter and the semiconductor substrate. The first photoelectric converter includes a first counter electrode, a first pixel electrode, and a first photoelectric conversion layer. The first photoelectric conversion layer is located between the first counter electrode and the first pixel electrode. The second photoelectric converter includes a second counter electrode, a second pixel electrode, and a second photoelectric conversion layer. The second photoelectric conversion layer is located between the second counter electrode and the second pixel electrode. The electric-charge storage region is electrically connected to the first pixel electrode and the second pixel electrode.

Abstract: An imaging device includes: a semiconductor substrate; a plurality of pixels arrayed in a first direction on the semiconductor substrate; and a first signal line positioned above the semiconductor substrate. Each of the plurality of pixels includes: a photoelectric converter that converts light into signal charges; a transistor that includes a gate electrically coupled to the first signal line; and a capacitive element. In a first pixel of the plurality of pixels, at least a part of the transistor overlaps the capacitive element in plan view, and the capacitive element does not overlap the entire width of the first signal line in plan view.

Abstract: A solid-state imaging device includes a plurality of pixels arrayed in a matrix, a plurality of first latch circuits, a first read bit line, a plurality of first driver circuits, a first amplifier, a second latch circuit, a second driver circuit, and a column scanning circuit. Each of the plurality of first latch circuits holds first pixel data which is obtained from a pixel located on the corresponding unit column. Each of the plurality of first driver circuits outputs the first pixel data, which is held in a corresponding one of the first latch circuits, to the first read bit line. The first amplifier amplifies a voltage of the first read bit line to generate first data. The second latch circuit holds the first data. The column scanning circuit sequentially outputs a plurality of the first pixel data by sequentially selecting the plurality of first driver circuits and selecting the second driver circuit. The second driver circuit outputs the first data to a read bit line different from the first read bit line.
