Abstract
An image sensing device to control flow of photocharges using a new method is disclosed. The image sensing device includes a photoelectric conversion region formed in a semiconductor substrate, a floating diffusion (FD) region formed apart from the photoelectric conversion region, a vertical pillar formed between the photoelectric conversion region and the floating diffusion region to transfer the photocharges from the photoelectric conversion region to the floating diffusion (FD) region, and a switching element located between the photoelectric conversion region and the floating diffusion (FD) region.
