Abstract
An image sensor includes: (1) a substrate having first and second surfaces opposing each other in a first direction and a plurality of unit pixels, (2) first and second photodiodes disposed in the substrate in each of the plurality of unit pixels and isolated from each other in a second direction perpendicular to the first direction, (3) a first device isolation film disposed between the plurality of unit pixels, and (4) a pixel internal isolation film disposed in at least one of the plurality of unit pixels. A second device isolation film overlaps at least one of the first and second photodiodes in the first direction. A pair of third device isolation films: (a) extend from the first device isolation film into the unit pixel in a third direction perpendicular to the first direction and the second direction and (b) oppose each other.
