| 20080265164 | THERMAL DETECTOR FOR ELECTROMAGNETIC RADIATION AND INFRARED DETECTION DEVICE USING SUCH DETECTORS - A thermal detector comprising a sensitive material having at least one electrical property of which varies with temperature; an electromagnetic radiation absorber which is in contact with the sensitive material; a substrate providing the function of support; and electrically conductive elements providing electrical continuity between sensitive material and substrate. The sensitive material is wholly or partly in the form of a sheet extending in a direction which is essentially perpendicular to the plane of the substrate. The sensitive material is suspended above the substrate by the absorber which is fixed to the sensitive material in the upper region of the sheet. The absorber is suspended by fixing means which is mechanically connected to the substrate. | 10-30-2008 |
| 20090121136 | Electromagnetic radiation detector with nanowire thermometer and method for producing same - The electromagnetic radiation detector comprises at least one membrane suspended above a substrate by at least one nanowire. The nanowire forms a thermoelement comprising an electrically conducting core and external layer, respectively doped of different types and insulated from one another by an electrical insulation layer. When the substrate and membrane are at different temperatures, the nanowire constitutes a thermometer providing measurement signals, by Seebeck effect, representative of heating of the membrane. | 05-14-2009 |
| 20090140145 | Electromagnetic radiation detector with nanowire connection and method for producing same - The electromagnetic radiation detector compromises at least one radiation absorption membrane transforming the absorbed energy into heat transmitted to at least one resistive thermometer having a resistance varying with temperature. Each absorption membrane is suspended above a substrate by a nanowire connected to the central area of the membrane. The nanowire comprises an electrically conducting core and an electrically conducting external layer electrically insulated from one another and respectively connected to measuring areas of said thermometer. The nanowire serves the purpose both of support for the membrane and of electrical connection between the measuring areas and a circuit arranged at the level of the substrate. | 06-04-2009 |
