  • Lithium microbattery protected by a cover
    Patent number: 9419254
    Abstract: A lithium microbattery comprises a stack of active layers containing lithium and a protective cover covering the stack of active layers. The protective cover is fixed to the stack of active layers by means of a layer of glue. A buffer structure comprising at least one alumina layer is arranged between the stack of active layers and the layer of glue, the buffer structure being in contact with said stack of active layers.
    Type: Grant

  • Deposition by spin coating of a patterned thin layer on a substrate
    Patent number: 9288912
    Abstract: The method for producing a patterned layer of first material on a surface of a substrate comprises the following successive steps: arranging a particle on the surface of the substrate; depositing a resin by spin coating on the surface of the substrate so as to form the patterned layer of first material and a hole passing through the layer of first material and opening onto the particle; the material of the particle and the resin being chosen such that the particle exerts a repulsive interaction with respect to the resin.

  • METHOD FOR DEPOSITING A CATALYTIC LAYER FOR A FUEL CELL
    Publication number: 20130052370
    Abstract: The present invention relates to a method for manufacturing a fuel cell electrode (E) by depositing a catalytic layer (2) on a diffusion layer (3), characterized in that said catalyst is deposited on the diffusion layer (3) by ionized physical vapor deposition (IPVD) in a vacuum chamber. The invention also relates to a method for manufacturing a fuel cell half-core comprising an ionic membrane (1), a catalytic layer (2) and a diffusion layer (3) by depositing the catalytic layer (2) on a support (1; 3), characterized in that said catalyst is deposited on the support (1; 3) by ionized physical vapor deposition (IPVD) in a vacuum chamber.
