InSb charge coupled infrared imaging device: The 20 element linear imager

The design and fabrication of the 8585 InSb charge coupled infrared imaging device (CCIRID) chip are reported. The InSb material characteristics are described along with mask and process modifications. Test results for the 2- and 20-element CCIRID's are discussed, including gate oxide characteristics, charge transfer efficiency, optical mode of operation, and development of the surface potential diagram.

A fully monolithic InSb infrared CCD array

Fully monolithic infrared CCD arrays fabricated in InSb are described. The process used in fabrication includes planar junction formation by ion implantation, and an aluminum and SiO2 overlapping CCD gate structure which makes use of conventional chemical and plasma etching. IR detection and readout is demonstrated with the arrays.
