Electromagnetic radiation detector and method of fabrication.

摘要

The detector comprises a thin film of detection material (8) sensitive to the radiation to be detected, having first and second faces (10,12). The first face is exposed directly to the radiation to be detected. A coating of resin (18) surrounds the thin film of detecting material and provides a ledge which surrounds the film. The thin film is incorporated into a circuit, by being mounted on micro-balls (16) which enable connection to a reading circuit (14). The resin has a thermal expansion coefficient similar to that of the reading circuit. The detection material may be CdHgTe.
