Development of hybrid PtSi focal plane arrays

A hybrid 256 X 256 PtSi focal plane array (FPA) with single output CMOS multiplexer readout in 24 micrometers pitch has successfully been developed. The device combines an excellent analog performance like noise equivalent temperature difference NETD < 100 mK (F/1.4, 20 ms, 300 K), dynamics > 12 bit, high output voltage > 2.5 V and reduced blooming with a very flexible digital layout, that enables customer specific applications like interlaced or progressive readout, variable integration time between 20 to 40 ms frametime and ultrashort times < 10 microsecond(s) , or subframe capability by just switching between clock patterns. The development is done in cooperation with DAIMLER BENZ Research and Technology, Munich, and TELEFUNKEN microelectronic TEMIC EZIS, Ulm. Reported are the digital features of the multiplexer results of the hybridization process and test results of our most recent FPA's. An outlook is given on the just started development of a 486 X 640 FPA with identical features, and on the development of integrated dewar cooler assemblies for this detector generation.
