8 February 2015 10μm pitch design of HgCdTe diode array in Sofradir

Sofradir recently presented Daphnis, its latest 10μm pitch XGA and HD720 products. Daphnis XGA is a 10μm pitch 1024x768 mid-wave infrared focal plane array. The development of small pixel pitch is opening the way to very compact products with high spatial resolution. This new product is key contribution to the HOT technology competition allowing reductions in size, weight and power of the overall package. This paper presents the recent developments achieved at Sofradir to make this 10μm pitch HgCdTe focal plane array. Electrical and electro-optical characterizations are presented to define the appropriate design of 10μm pitch diode array. The technological tradeoffs are explained to lower the dark current, to keep high quantum efficiency with a high operability above 110K, F/4.
