Abstract: Disclosed is an image sensor comprising a substrate that has a first surface and a second surface that face each other, an isolation pattern that defines a plurality of pixel regions in the substrate, a plurality of contact plugs on the first surface of the substrate and coupled to the isolation pattern, and a plurality of first micro-lens patterns on the second surface of the substrate. The contact plugs include a first contact plug and a second contact plug that neighbor each other. A portion of the isolation pattern extends to run across a first region and a second region in the substrate. The first region vertically overlaps the first contact plug. The second region vertically overlaps the second contact plug.
