  • Patent number: 7402457
    Abstract: A film, based on polyimide or epoxy, is laminated onto a surface of a substrate under a vacuum, so that the film closely covers the surface and adheres thereto. Contact surfaces to be formed on the surface are uncovered by opening windows in the film. A contact is established in a plane manner between each uncovered contact surface and a layer of metal. This establishes a large-surface contact providing high current density for power semiconductor chips.

    Abstract: A semiconductor chip device including a surface on which at least one electrical contact surface is provided. A foil from an electrically insulating material is applied, especially by vacuum, to the surface and rests closely to the surface and adheres to the surface. The foil, in the area of the contact surface, is provided with a window in which the contact surface is devoid of the foil and is contacted across a large area to at least one layer from an electroconductive material. In at least one embodiment, the layer from the electroconductive material is part of a flexible contact for electrically connecting the contact surface to at least one external connecting conductor.

  • Publication number: 20080124527
    Abstract: A method for enveloping components arranged on a substrate, with a film which is made of an electrically insulating plastic material, and the substrate. The film is placed on the components to be enveloped on the side thereof facing away from the substrate.

  • Publication number: 20070036944
    Abstract: An electrical component is mounted on a substrate. At least one electrical insulation film is provided to electrically insulate the component and at least section of the insulation film is connected to the component and the substrate, in such a way that the surface contours of said section of the insulation film are moulded to the surface contours formed by the component and the substrate. The insulation film has dielectric strength in relation to an electric field strength of more than 10 kV/mm and preferably more than 50 kV/mm. To produce the assembly, the insulation film is laminated onto the substrate, preferably by means of a vacuum. The component is in particular a power semiconductor component.

  • Publication number: 20060197222
    Abstract: An electrical component is placed on a substrate. At least one film comprising a plastic material is connected to the component and to the substrate in such a way that a surface contour defined by the component and the substrate is represent is represented in a surface contour of the part of the film. Said film is laminated onto the component and the substrate in such a way that the film follows the topology of the arrangement consisting of the component and the substrate. Said film is in contact with the component and the substrate in a positive and non-positive manner, and comprises a composite material containing a filler that is different to the plastic material. The processability and electrical properties of the film are influenced by the filler or the composite material obtained thereby. In this way, other functions can be integrated into the film. Said component is, for example, a power semiconductor component. An electrically insulating and thermoconductive film is used, for example.

  • Publication number: 20060162157
    Abstract: A component is connected to a circuit carrier via contacts which place the component at a distance from the circuit carrier. A foil is applied to the component and the circuit carrier so that it lies close to the surface of the circuit carrier on which the component is located and to the sides of the component not facing the circuit carrier. After being applied to the component and the circuit carrier the film is provided with a metal coating.

  • Patent number: 6685168
    Abstract: An electronic component such as a surface acoustic wave component has a chip a piezoelectric substrate with electrically conductive structures thereon and a base plate having external electrical terminal elements that are contacted to the electrically conductive structures of the chip. A protective film is applied onto the chip surface carrying the electrically conductive structures. The surface of the protective film facing away from the piezoelectric substrate carries electrical contact elements that are connected, to the electrically conductive structures of the chip via through-contacts in the protective film and/or directly via bumps, as well as to the electrical terminal elements of the base plate.

  • Patent number: 6555758
    Abstract: The multiple blank can be diced into individual blanks for electronic components, in particular surface acoustic wave components. Each of the individual blanks is suitable for contact to be made with chips in the flip-chip technique and for contact to be made with the individual blanks in the SMD technique, using external connections. The multiple blank has, for each individual blank, metalized areas which are located on a network which is integrated between layers of the multiple blank and leads to a connecting terminal. Bumps are built up by depositing metal by electroplating on the metalized areas.
