Scientific paper

A brief description of IR sensor devices for astronomical observation in the 4-17 micron wavelength band using Si:Ga detectors is given. These devices are to equip ISOCAM, a camera which will operate from the Infrared Space Observatory, the European satellite expected to be launched in May 1993, and C10-mu, a French astronomical camera based at the Canadian French Hawaii Telescope. These sensor devices are polylithic dies: the photoconductor array is hybridized by indium bumps to the readout circuit. Reliability tests show that neither thermal cycles nor strong acceleration or vibrations degrade the mechanical behavior of such a structure. A comparison between ISOCAM and the C10-mu detector is presented in tabular form.
