  • Publication number: 20240190120
    Abstract: A method for producing a multilayer structure includes the following steps: a) providing a first substrate, b) depositing a thick layer of a precursor formulation including a preceramic polymer filled with inorganic particles on the first substrate, c) providing a second substrate, d) adhesively bonding the thick layer and the second substrate, e) thinning the first substrate or the second substrate so as to obtain an active layer, f) applying a pyrolysis heat treatment so as to ceramize the preceramic polymer of the thick layer and to obtain a ceramic matrix composite material, the filler content and the nature of the inorganic particles being chosen so that the thick layer has a coefficient of thermal expansion which differs, at most, by 15% from that of the first substrate and from that of the second substrate.

  • Patent number: 10867883
    Abstract: DBC type structure, comprising an insulating support (22) coated with at least one conductive zone (20a) able to receive an electronic device, the conductive zone (20a) being in contact with the support (22), the insulating support incorporating means for thermal smoothing of the heat peak released by the component, these means comprising a cavity filled with a phase change material.

  • Patent number: 10798850
    Abstract: An electronic device includes an electronic component and a protective shield including a phase change material having a phase change temperature of between 20° C. and 90° C., an antivibration gel having hyperelastic and/or viscoelastic behavior at 20° C., and a separation barrier positioned so as to separate the phase change material and the antivibration gel. The antivibration gel is positioned, at least partly, in contact with the electronic component, and has a thermal conductivity of greater than 1 W/m·K at 20° C.
