Abstract
The invention relates to a radiation detection device including a silicon substrate and an infrared photodiode made of a material optimized for infrared detection. The substrate comprises a photosensitive area, readout circuits, and interconnects formed in an electrically-insulating material. The interconnects and the metal contact connect the readout circuits, the photosensitive areas, and the infrared photodiode. The detection device also comprises an infrared radiation filtering structure which covers the photosensitive area without covering the infrared photodiode.
