Abstract: Disclosed is an image sensor comprising a substrate that includes a plurality of pixel groups each including a plurality of pixel regions, a plurality of color filters two-dimensionally arranged on a first surface of the substrate, and a pixel separation structure in the substrate. The pixel separation structure includes a first part that defines each of the pixel regions and a second part connected to the first part. The second part runs across an inside of each of the pixel regions.
