Abstract
A semiconductor device includes a semiconductor substrate, a photo sensing region, and a plurality of nanostructures. The semiconductor substrate has a first dopant. The photo sensing region is embedded in the semiconductor substrate, has a top surface level with a top surface of the semiconductor substrate, and has a second dopant that is of a different conductivity type than the first dopant. The plurality of nanostructures is on the photo sensing region and is made of a material the same as the photo sensing region.
