Hybrid CdHgTe-silicon infrared focal plane arrays

Infrared sensitive focal planes consisting of matrices of photovoltaic CdHgTe diodes coupled to silicon multiplexing circuitry have been demonstrated in linear formats up to 1024 elements and in high density, multifunctional, two-dimensional arrays of up to 128×128 elements. The authors describe the technology used, in particular with respect to the radiometric performance achieved in hybrid arrays and to aspects such as manufacturability and reliability
