摘要： An image sensing device includes a pixel array configured to include a plurality of pixel groups arranged in a matrix structure. Each of the pixel groups includes an optical filter configured to selectively pass incident light, a plurality of photoelectric conversion regions disposed below the optical filter and arranged in a matrix structure, a first isolation structure disposed between the photoelectric conversion regions and other pixel groups, a plurality of second isolation structures disposed between two adjacent photoelectric conversion regions from among the photoelectric conversion regions, and a third isolation structure disposed between the second isolation structures, and configured to interconnect the second isolation structures. The third isolation structure includes a cavity region formed adjacent to contact any one of the photoelectric conversion regions.

摘要： An image sensing device includes photoelectric conversion elements structured to convert light into electrical signals, and a color filter layer structured to filter incident light towards the photoelectric conversion elements depending on a wavelength range of the incident light corresponding to colors of the incident light to allow the filtered light to be detected by the photoelectric conversion elements corresponding to the colors of the incident light. The color filter layer includes a plurality of first color filters as part of the different filters and structured to allow light at a wavelength range corresponding to a first color and arranged adjacent to each other. A distance between at least one of the first color filters and a corresponding photoelectric conversion element formed below the at least one of the first color filters is different from a distance between the remaining first color filters and corresponding photoelectric conversion elements, respectively.
