An image sensing device includes a pixel array including a plurality of pixels, each of pixels configured to generate a pixel signal corresponding to intensity of incident light, and a plurality of grid structures, each grid structure disposed to overlap with a boundary between adjacent pixels among the plurality of pixels and configured to include an air layer so as to optically isolate the adjacent pixels. Each of the grid structures includes regions that form a cross shape.

Image sensing device

An image sensing device includes a substrate layer in which an array of photoelectric conversion elements is formed, grid structures disposed over the substrate layer to divide space above the substrate into different sensing regions, each grid structure including an air layer, color filters formed to fill bottom portions of spaces between the grid structures, the color filters having a higher refractive index than the air layer, and a lens layer disposed over the grid structures and the color filters such that part of the lens layer fills top portions of the spaces between the grid structures, the lens layer having a higher refractive index than of the color filters.

An image sensing device and a method for forming the same are disclosed. The image sensing device includes a substrate including one or more photoelectric conversion elements, and a grid structure disposed over the substrate. The grid structure includes an air layer, a support film formed over the air layer, and a capping film formed at side surfaces of the air layer and the support film and at a top surface of the support film.
