The invention relates to a three-dimensional electronic module comprising an electronic device housed between a first substrate and a second substrate, said first and second substrates being electrically and/or thermally connected to one another by at least one and preferably two heat bridges added onto and rigidly connected to said first and second substrates. The invention also relates to an electronic system comprising at least two electronic modules mounted facing one another so as to sandwich a third substrate in contact with the second substrate thereof, respectively. The third substrate is configured to provide thermal and electrical coupling between the two electronic modules via the second substrate () thereof.

Electronic system comprising an electronic module

The module (PM) has an architecture with 3D stacking of the electronic power switching chips (IT, ID) and comprises first and second dielectric substrates (SH, SL) that are intended to come into thermal contact with first and second heat sinks (DH, DL), respectively, at least one pair of first and second stacked electronic power switching chips (IT, ID; IT, ID) and a common intermediate substrate (SC), the first and second electronic power switching chips being sandwiched between the first dielectric substrate and the common intermediate substrate and between the common intermediate substrate and the second dielectric substrate, respectively. According to the invention, the common intermediate substrate is a metal element formed as a single piece and comprises a central portion for the implantation of the electronic power switching chips and at least one.
