Abstract
An array of infra-red (IR) detectors for a CCD image sensor includes a plurality of spaced areas of a conductive material at the surface of a substrate of semiconductor material of one conductivity type with each conductive area forming a Schottky-barrier diode with the substrate to form the IR detectors. Each detector includes a high conductivity contact region within the substrate. Between the detector area is a guard band which consists of a region of a conductivity type opposite to that of the substrate within the substrate and around said detector area. The guard band is spaced from the contact regions and each conductive area overlaps a portion of its adjacent guard band.
