  • Electronic power module
    Patent number: 11887910
    Abstract: 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.
    Type: Grant
    Filed: September 2, 2019
    Date of Patent: January 30, 2024
    Assignees: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE

  • Electronic chip having channels through which a heat transport coolant can flow, electronic components and communication arm incorporating said chip
    Patent number: 8766433
    Abstract: The invention relates to an electronic chip, comprising: a semiconductor substrate (6) having an active area (8) formed by at least one P doped region and at least one N doped region which form one or more P-N junctions through which most of the useful current flows when said electronic chip is in a conductive state, and at least one channel (44) through which a heat transport coolant can flow, the channel(s) passing through at least said P or N doped region of the active area. Each channel (44) is rectilinear and passes through the substrate (6) in a direction which is collinear with a direction F to the nearest ±45°, where the direction F is perpendicular to the plane of the substrate.
