MONOLITHIC MULTISPECTRAL VISIBLE-AND-INFRARED IMAGER

摘要

The invention relates to a radiation-detecting device comprising a silicon substrate (11) and an infrared photodiode (21) made of a material (22) optimized for the detection of infrared. The substrate comprises a photosensitive zone (13), read circuits (12), and interconnects (15) formed in an electrically insulating material (16). The interconnects (15) and the metal contact (15-IR) connect the read circuits, the photosensitive zones (13) and the infrared photodiode (21). The radiation-detecting device also comprises a structure (18') for filtering infrared radiation, which covers the photosensitive zone (13) without covering the infrared photodiode (21).
