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.
