Latest Patents

One of his latest patents is titled "Selective patterning of metallization on a dielectric substrate." This patent discloses a method for selectively fabricating metallization on a dielectric substrate. The process involves sputtering a seed layer on a polymer dielectric, applying a patterned photoresist mask, etching exposed portions of the seed layer, stripping the photoresist, and depositing copper through electroless plating on the unetched seed layer. This innovative approach allows for the formation of well-adhering high-density copper lines without exposing the photoresist to the electroless bath.

Another significant patent by Randy is "Compliant electrically connective bumps for an adhesive flip chip." This invention details methods for forming compliant electrically connection bumps for an adhesive flip chip integrated circuit device. The process includes forming polymer bumps on a substrate or integrated circuit die, coating these bumps with a metallization layer, and involves steps such as coating a polymer material, curing it, and etching the bump pattern. The overcoating step includes electrolessly plating a ductile metal, such as gold, on the polymer bump.
