Abstract
A vertical semiconductor power device includes a plurality of semiconductor power cells connected to a bottom electric terminal disposed on a bottom surface of a semiconductor substrate and at least a top electrical terminal disposed on a top surface of the substrate and connected to the semiconductor power cells. The top electrical terminal further includes a solderable front metal for soldering to a conductor for providing an electric connection therefrom. In an exemplary embodiment, the conductor soldering to the solderable front metal includes a conductor of a high-heat-conductivity metal plate. In another exemplary embodiment, the conductor soldering to the solderable front metal includes a copper plate. In another exemplary embodiment, the solderable front metal includes a Ti/Ni/Au front metal. In another exemplary embodiment, the solderable front metal includes a Ti/Ni/Ag front metal.
