ABSTRACT:
A hybrid mosaic IR/CCD focal plane structure has high detector element packing densities which may be achieved using cost effective planar processing technology. The focal plane structure preferably includes an insulator layer over a silicon substrate which contains integrated circuit CCD signal processing circuitry. A mosaic photovoltaic (Hg,Cd)Te detector array is fabricated on the insulator layer. The photosignals from the detector array are coupled to the CCD circuitry by thin film electrical interconnects together with contact pads which extend through the insulator layer and are exposed at the surface of the insulator layer.
