Abstract (en)
[origin: WO02101843A1] The invention concerns an infrared sensor (2) comprising a plurality of pixels (12) having a structured layer (20) for infrared light absorption located at the sensor upper surface. The invention is characterised in that the absorption layer (20) is formed of colloidal particles, in particular graphite or metal oxide wafers embedded or sealed in a binder. The method for making such a sensor consists in forming the structured layer by deposit of the colloidal particles in accordance with a standard technique and then in eliminating partly the thus formed absorption layer to obtain a plurality of elementary absorption zones respectively associated with the plurality of pixels.
