  • Publication number: 20100208438
    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.

  • Publication number: 20100187700
    Abstract: A substrate which has at least one component, such as a semiconductor chip, arranged on it is manufactured from a film made of plastic material laminated onto a surface of the substrate and of the at least one component, where the surface has at least one contact area. First, the film to be laminated onto the surface of the substrate and the at least one component, or a film composite including the film, is arranged in a chamber such that the chamber is split by the film or film composite into a first chamber section and a second chamber section, which is isolated from the first chamber section so as to be gastight. A higher atmospheric pressure is provided or produced in the first chamber section than in the second chamber section; and contact is made between the surface of the substrate arranged in the second chamber section and the at least one component and the film or the film composite, which contact brings about the lamination of the film onto the surface.

  • Patent number: 7649272
    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: 20090029035
    Abstract: A method for selectively producing film laminates for packaging and for insulating unpackaged electronic components and functional patterns and corresponding device. The method coat surface regions of functional patterns arranged on a substrate and/or of surface regions of semiconductor chips arranged on the substrate. An insulation is to be effectively adapted in its properties to different requirements of functional patterns and/or electronic components. Film regions are laminated on surface regions in such a way that the properties of the plastics material of the film regions are adapted to the function of the film. This adaptation is individual and selective. Various films are used. The method is suitable in particular for coating or packaging electronic components or active and passive devices.

  • Publication number: 20090021923
    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.
