Image sensor

Abstract

Some embodiments of the present disclosure provide an image sensor, including a substrate, a plurality of first photodiodes, a first color filter unit and a first light intensity distributor. The first photodiodes are in the substrate. The first color filter unit is over the substrate. The first color filter unit includes a top-left region, a top region, a top-right region, a left region, a center region, a right region, a bottom-left region, a bottom region, and a bottom-right region over the first photodiodes, respectively. The first light intensity distributor is over the first color filter unit, in which the first light intensity distributor includes a plurality of first nanopillars configured to converge light to the center region or disperse light from the center region, and the center region has a highest or a lowest optical intensity.
