An electronic power module includes at least a semiconductor chip having at least one electronic power component and two metal layers between which the semiconductor chip is directly secured. At least a first of the two metal layers forms a redistribution layer having several distinct metal portions, each electrically connected to at least one electrical contact pad of the semiconductor chip, and/or at least one second of the two metal layers includes at least one first structured face arranged against the semiconductor chip and having at least one pad formed in a part of its thickness.

Electronic power module

An electronic power device including: a first electronic power component in which all the electrodes are arranged at a first main face of the first electronic power component; and an electric contact element in which a first main face is arranged against the first main face of the first electronic power component and which includes plural separate electrically conductive portions to which the electrodes of the first electronic power component are electrically connected. The first electronic power component and the electric contact element together form a stack such that a first lateral face of each of the portions of the electric contact element, substantially perpendicular to the first main face of the electric contact element, is arranged against at least one metallization of a support forming an electric contact of the first electronic power component.
