ABSTRACT:
An array of photovoltaic infrared radiation detector elements are formed in a body of infrared sensitive material, e.g. of cadmium mercury telluride. The body is present on a circuit substrate, which may comprise a silicon CCD for processing signals from the detector elements. An array of regions of a first conductivity type which form the p-n junctions of each detector element with an adjacent body part of opposite conductivity type, extend through the thickness of the body at side-walls of an array of apertures. Each aperture is associated with a detector element and is preferably formed by ion etching. These regions of the first conductivity type are electrically connected to substrate conductors in a simple and reliable manner by a metallization layer in the apertures, without rendering a significant area of the detector insensitive to radiation imaged onto the upper surface of the body. At least the back surface of the detector body (11) has a passivating layer over the area around and between the apertures, to enhance detector element performance. This back surface is secured to the circuit substrate by a layer of electrically insulating adhesive. The main body part is connected to a substrate conductor by a metallization at a surface portion which is outside of the area of the back surface and which is between the apertures. The resulting device is a closely-packed array of high performance detector elements on a circuit substrate. The spacing between adjacent apertures is 100 microns or less.
