Abstract

A 640 X 480 snapshot IRCMOS array with 25 micron pitch operating in the 3 - 5 microns range was fabricated and an image demonstrated at the Infrared Laboratory (LIR). The readout circuit with 2 pC charge handling capacity was designed and processed with a 1.2 micrometer design rules standard CMOS technology. Photovoltaic (PV) detectors were achieved by ion implantation in liquid phase epitaxy MCT layers and interconnected by indium bumps on the readout circuit. A description of the component is given and the main electro-optical characteristics are presented. The pixel operability is greater than 99.8% and a NEDT of 15 mK was measured at half dynamics. Excellent imagery has been obtained with this component operating at 77 K and f/2 optics.
