Abstract
An image sensing device includes a photoelectric conversion region configured to generate photocharges, a photogate region configured to overlap the photoelectric conversion region and allow the photocharges to be collected in the photoelectric conversion region, and a transfer gate disposed adjacent to the photogate region in a first direction and configured to transmit the photocharges to a floating diffusion region. The photogate region includes a first photogate in which a length extending in a second direction is longer than a length of the photoelectric conversion region extending in the second direction, and a second photogate in which a length extending in the second direction is shorter than a length of the photoelectric conversion region extending in the second direction. The first photogate includes a recess region formed to contact the photoelectric conversion region, and extend vertically from one surface of a region where the photoelectric conversion region is located.
