Multielement Infrared Detector Array Technology At The Santa Barbara Research Center

This paper presents an overview of multielement infrared detector array technology at the Santa Barbara Research Center. The paper discusses lead salt, indium antimonide, lead tin telluride, mercury cadmium telluride, and extrinsic germanium and silicon detector arrays. Examples of state-of-the-art arrays are presented for each of these detector materials. Two different hybrid detector/CCD array structures are described, an InSb/CCD sandwich structure using indium bump interconnects and a HgCdTe/CCD sandwich structure using evaporated interconnects. These techniques offer the advantages of low power, high density, low cost TDI on the focal plane.
