SUMMARY

To increase the sensitivity characteristics in a solid-state imaging device, it is desirable to increase the ratio of the area of openings for taking in light in a pixel to the area of the pixel.

Accordingly, an object of the present disclosure is to provide a solid-state imaging device and an imaging device that can increase the ratio of an opening in a pixel to the area of the pixel.

A solid-state imaging device according to one aspect of the present disclosure includes: a plurality of pixels arranged in matrix form on a semiconductor substrate, each of the pixels including a photoelectric converter that converts received light into a signal charge, and a plurality of first transfer electrodes that accumulate and transfer the signal charge read out from the photoelectric converter; and a plurality of control lines connected to mutually-corresponding ones of the first transfer electrodes in a plurality of pixels arranged in a specific row in the arrangement of the plurality of pixels. The plurality of pixels include a plurality of first pixels and a plurality of second pixels. Each of the plurality of first pixels further includes a floating diffusion layer that accumulates the transferred signal charge, and a readout circuit that reads out the signal charge accumulated in the floating diffusion layer. Each of the second pixels shares the floating diffusion layer with one of the first pixels arranged in a column direction of the arrangement of the plurality of pixels. At least some of the plurality of control lines are further connected to at least one of the first transfer electrodes of pixels that are arranged adjacent in the column direction to respective ones of the plurality of pixels arranged in the specific row and that share at least one of the floating diffusion layers.

An imaging device according to another aspect of the present disclosure includes the above-described solid-state imaging device, a light source that emits infrared light in pulses at a plurality of timings in each of exposure periods within a single frame period, and a processor that generates a range image based on a signal read out by the readout circuit.

According to the solid-state imaging device and imaging device configured as described above, the ratio of an opening in a pixel to the area of the pixel can be increased more than in the past.
