Abstract
An image sensing device is disclosed. The image sensing device includes a semiconductor substrate and a lens layer. The semiconductor substrate includes a first surface and a second surface opposite to the first surface, and includes a photoelectric conversion element that generates photocharges in response to light incident to the photoelectric conversion element via the first surface. The lens layer is disposed over the semiconductor substrate to direct light through the first surface of the semiconductor substrate into the substrate lens which further directs the incident light into the photoelectric conversion element. The semiconductor substrate is structured to include a substrate lens formed by etching the first surface to a predetermined depth and located between the first surface and the photoelectric conversion element to direct incident light via the first surface to the photoelectric conversion element.
