Abstract
A light sensor includes first and second neighboring photodiodes that are separated from each other by a space. A light-absorbing material is positioned at a location which is vertically above the space between the neighboring photodiodes. A first multilayer interference filter includes a central portion located vertically above the first photodiode and a peripheral portion that at least partly extends to rest on top of and in contact with the light-absorbing material.
