Paper Abstract

Sofradir has developed a series of products by using the second generation IRFPA technology developed by the French research laboratory Lir with the support of the French MoD. This technology is based on the use of MCT photovoltaic diodes coupled to silicon readout circuit thanks to indium bump technique. The maturity is so good that producibility of such high performance, high complexity components was demonstrated several years ago. As a consequence, Sofradir produces now in quantities large IRFPAs sensitive in the 8 - 12 micrometers waveband. Beyond this success, Lir and Sofradir continue to update the technology and to build new products. Developments are on progress for long monolithic TDI arrays 3 to 5 and 8 to 12 micrometers , 480 X 4, 576 X 4 or staring arrays using CMOS or CCD readout circuits. All the work is performed within the frame of producibility and reliability.
