Image sensing device

Abstract

An image sensing device includes a plurality of unit pixels, wherein each of the unit pixels includes a photoelectric conversion region disposed in a substrate, and configured to generate photocharges in response to incident light, a control region disposed in the substrate and configured to receive a control signal and generate a current in the substrate based on the control signal to carry and move the photocharges generated in the photoelectric conversion region, a detection region disposed in the substrate and configured to receive the current and to capture the photocharges carried by the current and a guard ring region configured to surround the control region, and wherein the hole current flows between the control region and the guard ring region.
