Ralf Jörke has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8018064
    Abstract: An integrated circuit and an arrangement including a semiconductor device and a connecting element and method for producing such an arrangement is disclosed. One embodiment provides a semiconductor element having a first contact face and a second contact face. The first contact face and the second contact face extend in a first lateral direction. An electrically conductive connecting element which has a third contact face electrically contacts the semiconductor element. The connecting element includes a trench system. A first trench of this trench system extends from the third contact face into the connecting element.
    Type: Grant
    Filed: May 31, 2007
    Date of Patent: September 13, 2011
    Assignee: Infineon Technologies AG
    Inventors: Uwe Kellner-Werdehausen, Reiner Barthelmess, Hans-Joachim Schulze, Heinrich Gerstenkoeper, Ralf Joerke

  • Patent number: 7027303
    Abstract: The inventive electronic power module is provided for effecting the smooth starting of motors. The module essentially includes two semiconductor elements, which are connected in an electrically anti-parallel manner and which are clamped between two metal bars, having a high thermal capacity, e.g. made of copper, by a pressing device. After being intermediately stored in the metal bars, the heat loss of the semiconductor elements is dissipated by cooling bodies placed on the metal bars.

  • Patent number: 6431259
    Abstract: In order to fix a semiconductor module to a heat sink, the semiconductor module and the heat sink are clamped together by one or more clips made of spring material, i.e. spring clips. A mutually matched form of the spring clips optimizes the connection between the heat sink and the semiconductor modules. A respective connection of clip body and heat sink or semiconductor module is advantageously effective in such a way that the spring clip can be inserted into a respective spring clip receptacle and holds automatically on/in the heat sink or semiconductor module.
