description An image sensing device that includes a reinforced structure is disclosed. The image sensing device includes a semiconductor substrate structured to include a pixel region including a plurality of unit pixels and a peripheral region located outside the pixel region, a plurality of microlenses disposed over the semiconductor substrate in the pixel region, a structural reinforcement layer disposed over the semiconductor substrate in the peripheral region, and a lens capping layer structured to cover the microlenses and at least of the structural reinforcement layer. The structural reinforcement layer includes a plurality of fingers each finger vertically structured to have a rounded upper end and laterally extend to have a predetermined length toward the pixel region. The fingers are consecutively arranged and connected to each other in a lateral direction, and side surfaces of fingers are in contact with side surfaces of immediately adjacent fingers.
