Abstract
A method for manufacturing a power electronic module by additive manufacturing includes the step of depositing a layer of an electrically conductive nanoporous material on a substrate that includes an electrically insulating layer and at least one layer of conductive metal material, called a metallized substrate. The method further includes the step of placing an element, for example an active component of the semiconductor power component type, on the layer of nanoporous material and sintering the layer of nanoporous material, so as to ensure a mechanical and electrical connection between said element and the metallized substrate.

A method of manufacturing a power electronic module by additive manufacturing, comprising the steps of:
- depositing in a single step, by electrodeposition, a layer of electrically conductive nanoporous material directly on a substrate comprising an electrically insulating layer and at least one layer of conductive metal material, called a metallized substrate,
- placing an element on the layer of nanoporous material and sintering the layer of nanoporous material to ensure a mechanical and electrical connection between said element and the metallized substrate,
- making or fixing at least one sacrificial preform of polymer material on at least one face of the metallized substrate,
- depositing a first metal layer on the at least one sacrificial preform, and
- depositing a second metal layer on the first metal layer by electroforming to form a metallic structure defined by said at least one sacrificial preform, wherein said at least one sacrificial preform is subsequently removed.
