Patent ID: 8264853

Claim:
A 3D electronic module comprising: a stack having a first slice and a second slice, wherein each of the first and second slices has several electronic components; an electrically insulating resin clad with the electronic components; and electrical connection elements on a face of the slice, wherein the first slice further includes, on said face of the first slice, a set of electrically conductive protrusions, and an electrically conductive track, wherein at least one of said electrical connection elements is connected to the set of electrically conductive protrusions via the electrically conductive track, wherein the first slice has, between two of the electronic components, a zone of electrically insulating material, traversing a thickness of the first slice, wherein the second slice has a zone of electrically insulating material traversing a thickness of the second slice, and an electrically conductive element traversing said second slice in the zone of electrically insulating material, and wherein the electrically conductive element and the electrically conductive protrusions are respectively constituted by a material having a specified hardness, the hardness of the material of the electrically conductive element being less than that of the material of the electrically conductive protrusions, and wherein the set of the electrically conductive protrusions of the first slice is embedded into the electrically conductive element of the second slice.
