Abstract
An image sensor includes a plurality of photo diodes disposed at a semiconductor substrate, and a splitter disposed on the photo diodes. The splitter splits an incident light depending on a wavelength so that split light of different colors enters different photo diodes, respectively. The splitter includes a first pattern structure having a cross-sectional structure in which a plurality of refractive layer patterns are deposited in a lateral direction.
