Abstract
Image sensing devices are disclosed. In some implementations, an image sensing device may include a substrate having an upper surface and a lower surface, a photoelectric conversion device formed in the substrate and structured to convert incident light into an electrical signal carrying information associated with the incident light, and an isolation structure formed in the substrate along at least a side surface and a bottom surface of the photoelectric conversion device. The isolation structure comprises a first isolation region which extends from the upper surface of the substrate to a first depth in the substrate to surround the side surface of the photoelectric conversion device, and a second isolation region which is formed in the substrate below the bottom surface of the photoelectric conversion device, the second isolation region electrically connected with the first isolation region.
