Abstract
An apparatus and method for forming optical black pixels having uniformly low dark current. Optical Black opacity is increased without having to increase Ti/TiN layer thickness. A hybrid approach is utilized combining a Ti/TiN OB layer in conjunction with in-pixel metal stubs that further occlude the focal radius of each pixel's incoming light beam. Additional metal layers can be used to increase the opacity into the infrared region.
