Abstract
An image sensor includes a group of sensor units, a color filter layer disposed within the group of sensor units, and a dielectric structure and a metasurface disposed corresponding to the color filter layer. The metasurface includes a plurality of peripheral nanoposts located at corners of the group of sensor units from top view, respectively, a central nanopost enclosed by the plurality of peripheral nanoposts, and a filling material laterally surrounding the plurality of peripheral nanoposts and the central nanopost. The central nanopost is offset from a center point of the group of sensor units by a distance from top view.
