  • Patent number: 8261439
    Abstract: One unhoused electronic component, e.g., a semiconductor power component, has at least one connecting surface disposed on a top side and/or on a bottom side for fastening and/or for electric contacting. One side of the component is attached to and/or electrically contacts a direct copper bonding ceramic substrate, at an opposing connecting surface in the region of the connecting surface. An electrically insulating carrier film is created on the substrate on the side facing the component outside the region of the connecting surface and extending beyond the bottom side. An electrically conducting conductor part is attached to and/or electrically contacts the connecting surface on the top side. A pre-formed, three dimensional structure is formed extending beyond the area of the top side, thus creating an electrically insulating mass between the carrier film and the three-dimensional structure of the conductor part.

  • Patent number: 8191243
    Abstract: In one embodiment of the present invention, a method is disclosed for contacting at least one electric contact surface on a surface of a substrate and/or a surface of a semiconductor chip arranged on a substrate. According to one embodiment of the invention, a film of electrically insulating plastic material is laminated onto the surfaces. A large-area contacting of the contact surfaces, which are freely accessible via the openings in the film, with a layer of electrically conductive material is then carried out. It is the aim of a planar electric contacting method to produce openings in an insulation during a short period of processing time. In particular, openings are to be positioned at a precise position to the contact surfaces. To achieve this, openings are produced in the film of electrically insulating plastic material in the region of the contact surface to be contacted by means of laser cutting and prior to laminating. This method is suitable for all planar contacting processes.
