  • Semiconductor device
    Patent number: 11139263
    Abstract: A semiconductor device comprising at least a semiconductor component, a heat sink, a connecting element and an electrical circuit connected to the heat sink in an electrically conductive manner; wherein the semiconductor component and the heat sink are arranged at a distance from one another and are electrically and thermally conductively connected via the connecting element, wherein an electrical current can be supplied to the electrical circuit via the heat sink.
    Type: Grant
    Filed: April 13, 2020
    Date of Patent: October 5, 2021
    Assignee: VOLKSWAGEN AKTIENGESELLSCHAFT
