Abstract
A method of forming an image detector from an optical detector having a first side connected to a substrate and a second side opposite the first side. The method includes: receiving the detector; electrically coupling the second side of the detector to a read out integrated circuit (ROIC); securing the detector to the ROIC with an adhesive, wherein the adhesive surrounds the detector and at least a portion of the substrate. The method also includes chemically removing at least some of the substrate to expose an exposed portion of the first side of the detector. Such removal results in the formation of an adhesive fence from the adhesive that has a fence upper surface that is above the first side on which an optical element is mounted such that an air gap exists between the first side of the detector and the optical element.
