ABSTRACT:
A semiconductor range-finding element and a solid-state imaging device, which can provide a smaller dark current and a removal of reset noise. With n-type buried charge-generation region, buried charge-transfer regions, buried charge read-out regions buried in a surface of p-type semiconductor layer, an insulating film covering these regions, transfer gate electrodes arranged on the insulating film for transferring the signal charges to the buried charge-transfer regions, read-out gate electrodes arranged on the insulating film for transferring the signal charges to the buried charge read-out regions, after receiving a light pulse by the buried charge-generation region, in the semiconductor layer just under the buried charge-generation region, an optical signal is converted into signal charges, and a distance from a target sample is determined by a distribution ratio of the signal charges accumulated in the buried charge-transfer regions.
