  • Patent number: 11594475
    Abstract: A method of fabricating an electronic power module by additive manufacturing, the electronic module including a substrate having an electrically insulating plate presenting opposite first and second faces, with a first metal layer arranged directly on the first face of the insulating plate, and a second metal layer arranged directly on the second face of the insulating plate. At least one of the metal layers is made by a step of depositing a thin layer of copper and a step of annealing the metal layer, and the method further includes a step of forming at least one thermomechanical transition layer on at least one of the first and second metal layers, the at least one thermomechanical transition layer including a material presenting a coefficient of thermal expansion that is less than that of the metal of the metal layer.
    Type: Grant
