Abstract
We disclose an array of Infra-Red (IR) detectors comprising at least one dielectric membrane formed on a semiconductor substrate comprising an etched portion; at least two IR detectors, and at least one patterned layer formed within or on one or both sides of the said dielectric membrane for controlling the IR absorption of at least one of the IR detectors. The patterned layer comprises laterally spaced structures.
