<p>Method to process spectrally selective uncooled lead selenide infrared detectors consisting in: 1) Substrate selection and preparation 2) multilayer interference filters deposition and delineation 3) polycrystalline lead selenide infrared detectors processing on interference filters consisting in: 3a) metal deposition; 3b) metal delineation; 3c) Sensor delineation; 3d) PbSe deposition by thermal evaporation in vacuum; 3f) Sensor developing 3g) Thermal treatment for sensitizing the active material; 3h) Deposition of a pasivating layer on the active material. The method is unique because allows to process, on the same substrate, different geometries of uncooled infrared detectors including, single element, multielement, linear arrays, 2-dimensional arrays etc. with the response of each one of the sensors modified by their corresponding interference filter as designed. Applications include low cost multicolor infrared detectors to control of process, gas analysis, temperature measurement, military applications etc.</p> |
