Light-receiving device

Abstract

A light-receiving device according to an embodiment of the present disclosure includes: a first substrate including a plurality of photoelectric conversion sections that photoelectrically converts light; a second substrate including a plurality of readout circuits that outputs a first signal based on electric charge photoelectrically converted by the photoelectric conversion sections; and a first through-electrode coupled to each of the readout circuits and penetrating the second substrate. The first substrate and the second substrate are stacked by bonding between electrodes to allow a first surface of the first substrate on which an element is formed and a second surface of the second substrate on which an element is formed to be opposed to each other. The first through-electrode is provided for each of the readout circuits or for every plurality of readout circuits.
