  • Patent number: 7745913
    Abstract: A power semiconductor component includes at least one power semiconductor chip and surface-mountable external contacts. The power semiconductor chip includes large-area contact areas on its top side and its rear side, which cover essentially the entire top side and rear side, respectively. The top side also includes, alongside the large-area contact area, a small-area contact area; the areal extent of the small-area contact is at least ten times smaller than the areal extent of the large-area contact areas. The small-area contact area is connected to an individual external contact of the power semiconductor component via a bonding wire connection. The large-area contact area of the top side is connected to external contacts via a bonding tape.

  • Patent number: 7728415
    Abstract: A power semiconductor component stack, using lead technology with surface-mountable external contacts, includes at least two MOSFET power semiconductor components each having a top side and an underside. The underside includes: a drain external contact area, a source external contact area and a gate external contact area. The top side includes at least one source external contact area and a gate external contact area. The gate external contact areas on the top side and the underside are electrically connected to one another. The power semiconductor component stack is a series circuit or a parallel circuit of MOSFET power semiconductor components arranged one above another in a plastic housing composition.

  • Patent number: 7579675
    Abstract: A semiconductor device having surface-mountable external contact areas and a method for producing the same is disclosed. The surface-mountable external contacts are arranged as flat external contacts on the underside of the semiconductor device. In one embodiment, the semiconductor chip of the semiconductor device has a source contact area and a gate contact area on its top side and a drain contact area on its rear side. The source contact area is fixed on a cutout of a heat sink, which is connected to a source external contact, a top side of the heat sink partly forming the top side of the semiconductor device. The drain contact area is electrically connected to a drain external contact and the gate contact area is electrically connected via a connecting element to a gate external contact on the underside of the semiconductor device. Consequently, the semiconductor device as areas which dissipate the heat loss both on the underside and on the top side.
