Abstract
One aspect of the invention relates to a power semiconductor device in lead frame technology and a method for producing the same. The power semiconductor device has a vertical current path through a power semiconductor chip. The power semiconductor chip has at least one large-area electrode on its top side and a large-area electrode on its rear side. The rear side electrode is surface-mounted on a lead frame chip island of a lead frame and the top side electrode is electrically connected to an internal lead of the lead frame via a connecting element. The connecting element has an electrically conductive film on a surface facing the top side electrode, the electrically conductive film extending from the top side electrode to the internal lead.
