Abstract

Second generation infrared imaging systems require high density focal plane arrays for staring applications. To meet this need, a focal plane structure using HgCdTe photodiodes for detectors and Si CCDs for signal processing has been developed. Although conventional ion-implanted hybrid arrays have successfully been interfaced to CCD multiplexers, hybrid arrays fabricated on liquid phase epitaxial (LPE) layers offer some inherent advantages with respect to performance, processing and yields. It has been determined that heterostructure diodes fabricated by a Hg infinite melt LPE technique give superior performance relative to conventional ion-implanted devices. The devices exhibit high RoA products and good compositional uni formity. Data is presented on devices fabricated for both 8 to 12 μm and 3 to 5 μm applications.
