Development of InSb CID Array Technology.
Abstract
Further improvement on both line and two-dimensional InSb CID arrays has been made. Array performance has been improved by using thinner-gate oxide, thicker field oxide, lower-doping substrate materials, and lower noise amplifier. The co-planar two-dimensional array structure also has been further improved. Array performance efficiencies, (which include transfer, quantum and readout efficiencies) of over 30%, and transfer efficiencies of over 98% have been measured on two dimensional arrays. Effort on a low-noise preamplifier has been carried out and performance of the JFET preamplifier is much better than that of the MOSFET. The NETD for a line array was found to be about 0.1K using a JFET preamplifier and 0.5K using a MOSFET. The measurement was made with a narrow spectral filter of 3.6 to 4.0 micrometers, f/3.25 lens system, and a 500 microsecond integration time. (Author)
