Latest Patents

Harrover holds a patent for a low-cost method for forming elevated metal bumps on integrated circuits. This patent describes a process where elevated metal contact bumps are created on a microelectronic semiconductor circuit using aluminum-palladium metallization as a base for selective electroless plating. The method allows for the sequential deposition of aluminum and palladium in a single operation, minimizing exposure to the atmosphere. The aluminum-palladium film is then patterned using an etchant that attacks both metals at a similar rate. Finally, an insulation layer is applied, with apertures opened to expose palladium for immersion in an electroless plating bath of ionic copper or nickel, facilitating bump formation.
