A method for producing an electrically conducting metal contact on a semiconductor component having a coating on the surface of a semiconductor substrate. In order to keep transfer resistances low while maintaining good mechanical strength, the invention proposes applying a particle-containing fluid onto the coating, where the particles contain at least metal particles and glass frits, curing the fluid while simultaneously forming metal areas in the substrate through heat treatment, removing the cured fluid and the areas of the coating covered by the fluid, and depositing, for the purposes of forming the contact without using intermediate layers, electrically conducting material from a solution onto areas of the semiconductor component in which the coating is removed while at the same time conductively connecting the metal areas present in said areas on the substrate.

Method for producing a metal contact on a coated semiconductor substrate

A process for forming at least one local contact area of a substrate of an electrical component for contacting the contact area with a connector, in which the substrate, on the contact side, is provided with a sintered porous metal layer. To make available a mechanically durable, electrically faultless solderable contact area, it is proposed that the porous layer be compacted and/or removed in the contact area to be formed.
