Abstract:
1. A method for producing a wiring substrate of a semiconductor component comprising external contact pads for fitting external contacts, the method comprising: producing a baseplate with through contacts at predetermined positions, wherein the baseplate comprises a precursor of a polymer; selectively applying a layer comprising a rubber-elastic material to a top side of the baseplate, wherein the layer comprises rubber-elastic material pads that are spaced apart from one another; laminating a copper film and pressing the rubber-elastic material pads with the external contact pads into the precursor of the polymer of the baseplate to embed the rubber-elastic material pads in the baseplate and form a coplanar boundary layer between the copper film and the top side of the baseplate; structuring the copper film to form external contact pads and feed lines to the through contacts; and curing the precursor of polymer of the baseplate to form a rigid self-supporting wiring substrate.
