An image sensor includes: a substrate having a plurality of unit pixel region; a light receiving element formed in the substrate at the unit pixel region; an interlayer dielectric layer formed over the substrate; a lightguide formed in the interlayer dielectric layer for the light receiving element; a light focusing pattern formed over the interlayer dielectric layer at the pixel region; a planarization layer formed over the substrate and covering the light focusing pattern; and a lens formed over the planarization layer at the pixel region. |
