Abstract
A solid-state imaging device includes: pixels arranged in a matrix on a semiconductor substrate. Each of the pixels includes: a photoelectric converter that converts received light into a signal charge; at least one read gate that reads the signal charge from the photoelectric converter; charge accumulators that each accumulate the signal charge read by the at least one read gate; and a charge holder that receives, from one of the charge accumulators, transfer of the signal charge accumulated in the charge accumulator, holds the signal charge, and transfers, to one of the charge accumulators, the signal charge held, each of the charge accumulators includes a part of a transfer channel and a part of a transfer electrode overlapping with the part of the transfer channel in a planar view of the semiconductor substrate, and the transfer channel per one pixel comprises transfer channels.
