Latest Patents

David W. Rich holds a patent for a stripped gold plating process. This method is designed for fabricating metallurgical contacts that facilitate thermocompression bonds to a metallized ceramic substrate. The process involves placing a nickel layer on the substrate and covering it with an immersion layer of gold. The gold immersion layer is selectively removed from specific locations where thermocompression-bonded contacts are needed. This removal is achieved using a chemical stripper, followed by heavy gold electroplating on the desired locations. The assemblage is then heat-treated before the placement of the thermocompression-bonded contacts. This innovative approach enhances the reliability and efficiency of semiconductor chip mounting.
