Abstract
An image sensing device includes a photoelectric device disposed within a semiconductor substrate, and a separation structure and electrode structures disposed within the semiconductor substrate, and surrounding the photoelectric device. The separation structure includes a first conductive pattern, and a first insulating spacer between the first conductive pattern and the semiconductor substrate. A respective one of the electrode structures includes a second conductive pattern, and a second insulating spacer between the second conductive pattern and the semiconductor substrate. The first conductive pattern and the second conductive pattern are formed of the same conductive material.
