Abstract
A system for infrared sensing has thermally sensitive picture elements within a substrate; bias contact areas within the substrate and around a periphery of the thermally sensitive picture elements; a common electrode on a front side of the thermally sensitive picture elements and the bias contact areas; an optical coating on top of the common electrode; a first electrical contact metal on a backside of the thermally sensitive picture elements; and a second electrical contact metal connected to the bias contact areas on a backside of the bias contact areas and electrically connected to the common electrode. The bias contact areas may include a conductive substrate area. In addition, the device may be connected to an integrated circuit by an ohmic connection to the first and/or the second electrical contact metal.
