Abstract
An image sensing device includes a substrate including a front side and a back side that are opposite to each other, wherein the image sensing device is structured to operate by receiving incident light through the back side of the substrate; a depletion region disposed in the substrate to be in contact with the back side of the substrate; an epitaxial layer disposed in the substrate to be in contact with or near the front side of the substrate; and a plurality of detection structures disposed in the epitaxial layer, each configured to capture photocharge generated by incident light and move by a current flowing in the epitaxial layer.
