Abstract
High resolution infrared imaging system calls for very long scanning arrays with several thousands of detectors and high performance. This paper presents the recent technological developments and the electro-optical performances obtained at LETI/LIR (infrared laboratory) on 1500 detector linear HgCdTe arrays working in the 3 - 5 and 8 - 10 micrometer spectral ranges. These very large arrays (length approximately equals 50 mm) have an indirect hybrid architecture composed of butted HgCdTe PV detection circuits and Si CMOS readouts hybridized on a mechanically close-matched fanout substrate. Defect free dicing and butting, respecting the detector pitch, is made by accurate and non damaging techniques.
