Paper Abstract

A high performance 640 X 480 focal plane array has been developed for the 1 - 5 micron band with excellent sensitivity at temperatures below 120 K. The detectors are processed on 2' or 3' diameter PACE-I (producible alternative to CdTe for epitaxy) HgCdTe material. The multiplexer is a direct injection input, switched-FET device with four independent quadrants. The detector is hybridized to the multiplexer through indium columns and is characterized. A mean camera NE(Delta) T (noise equivalent temperature difference) of 13 mK has been achieved for temperatures <EQ 120 K. Background-limited (BLIP) D* of 1 X 1012 Jones (cm-(root)Hz/W) has been measured for 1014 phs/cm2-s background at 95 K. The hybrids have been thermally cycled for 15 times with no interconnect loss. Interconnect yields as high as 99.3% have been achieved.
