Paper Abstract

Preliminary evaluation of the performance characteristics of a new two-dimensional multiplexed MWIR focal plane array assembly is discussed. The CMOS BDRO multiplexer individually buffers each detector in the 64 x 64 element array. This multiplexer was designed with an emphasis on low-background applications and results will be reported accordingly. The detector is an array of photovoltaic indium antimonide (InSb) diodes bump bonded, using indium columns, to the silicon multiplexer and is thinned for back-side illumination. The detector element size is 87 x 87 microns on 100 micron centers. Charge storage capacity is approximately 4 x 106 electrons. The InSb array substrate is thinned to approximately 15 microns and spectrally responsive in the 1 to 5.5 μm region. Electro-optical test results include the performance parameters: quantum efficiency, signal linearity, and dark current. IR images will be presented to illustrate initial array performance.
