Abstract:
1. A semiconductor device comprising: an image sensor comprising a first pixel region and a second pixel region in a substrate, the first pixel region being adjacent to the second pixel region and also being adjacent to a first side of the substrate; a first color filter over the first pixel region, wherein the color filter is located adjacent to a second side of the substrate opposite the first side of the substrate; a second color filter over the second pixel region; a gap between the first color filter and the second color filter, wherein the gap is void of solid material; and a gap covering layer over the first color filter and the second color filter, wherein the gap covering layer is a single material and also extends into a region between the first color filter and the gap, and covers a sidewall of the first color filter from a top of the first color filter to a bottom of the first color filter.
