Latest Patents
Kummer's latest patents include a method of making a metallic support carrier for semiconductor elements. This innovative method aims to improve the bonding layer for connecting wires to semiconductor chips. The bonding layer is designed as a spongy, microporous structure, which is applied to discrete positions of the contact strips through screen printing. It is secured to the metallic connecting strip by a diffusion zone. The bonding layer can comprise metals such as gold, palladium, silver, aluminum, and copper, or an alloy of at least two of these metals. The layer thickness ranges from 2 to 30 micrometers, with a preference for 3 to 10 micrometers. The process involves using a paste of the metal in an evaporative organic carrier, which is eliminated by heating, resulting in a spongy microporous structure bonded to the substrate carrier.
