  • Publication number: 20250385228
    Abstract: Various embodiments of the teachings herein include a power electronics assembly having a substrate with two loadable power modules. The two modules each comprise: a power substrate with a first metallization; a switchable die with power interfaces; an interposer; and two contact elements, each of which provides an electrical contact for one of the power interfaces at the interposer. The die is joined to the metallization of the power substrate and to the interposer. A gap is defined between the first substrate, the interposer, and the die, and closed off by an insulation material so the die is surrounded by the insulation material, the power substrate, and the interposer. At least one of the contact elements projects through the interposer and/or is part of the interposer.

  • Patent number: 11756857
    Abstract: An electronic circuit has three circuit carriers and two semiconductor components. A first semiconductor component contacts with its upper side an underside of a first circuit carrier, and with its underside an upper side of a second circuit carrier. The first circuit carrier has vias, with a first via connecting the first semiconductor component to a first conducting path and a second via connecting a connection element forming a second conducting path providing an integral connection between the circuit carriers. A second semiconductor component contacts the underside of the first circuit carrier and is electrically connected to the first or second conducting path. An underside of the second semiconductor component contacts an upper side of the third circuit carrier. A lateral thermal expansion coefficient of the first circuit carrier is greater than a lateral thermal expansion coefficient of both the second and the third circuit carrier.
