DEVICE FOR DETECTING THREE-DIMENSIONAL ELECTROMAGNETIC RADIATION AND METHOD FOR MAKING SAME

摘要

The invention concerns a device for detecting electromagnetic radiation comprising at least a detecting circuit including a non-cooled thermal detector (4) and an associated reading circuit (2). The invention is characterised in that it comprises: a substrate (8) forming a vacuum cavity (10), wherein are arranged the thermal detector and the reading circuit; a window (3) transparent to the radiation, arranged above the cavity and closing same; closure means (12, 13) for hermetically fixing the window on the substrate; and electrical connection means (9) inserted in the window providing sealed connection between the detection circuit and the processing elements outside the cavity. The invention also concerns the method for making said device.
