  • POWER SEMICONDUCTOR DEVICE AND METHOD OF PRODUCING POWER SEMICONDUCTOR DEVICE
    Publication number: 20230082571
    Abstract: A power semiconductor device includes a semiconductor body and a first terminal at the semiconductor body. The first terminal has a first side for adjoining an encapsulation and a second side for adjoining the semiconductor body. The first terminal includes, at the first side, a top layer; and, at the second side, a base layer coupled with the top layer, wherein a sidewall of the top layer and/or a sidewall of the base layer is arranged in an angle smaller than 85° with respect to a plane.
