Paper Abstract

Large area, very long wavelength infrared focal plane arrays will be required for future astronomy, defense, commercial, and other applications. Rockwell International has developed and extended the state-of-the-art of these arrays, resulting in the world's first 128 X 128 element blocked impurity band (BIB) detector focal plane arrays. Rockwell's advanced epitaxial process control has made possible the fabrication of large area, uniform BIB detector arrays, having pixel spacings as small as 75 micrometers . Using standard indium bumping techniques, these detectors are mated to multiplexers which incorporate a wide variety of design features. Characterization of these arrays has shown low intrinsic noise, excellent response uniformity, response linearity over a wide dynamic range, and over 97% pixel operability. The results achieved demonstrate the feasibility and versatility of very long wavelength infrared (to 28 micrometers ) focal plane array technology based on BIB detectors.
