Latest Patents

Underwood holds a patent for an "Interface between titanium and aluminum-alloy in metal stack." This invention addresses an improvement in a metal stack used for interconnecting structures in an integrated circuit. The improvement involves entrapping nitrogen in a titanium layer at the interface where it contacts a bulk conductor layer, such as an aluminum-copper alloy layer. The entrapped nitrogen prevents the formation of titanium aluminide, which reduces current densities and enhances the electromigration properties of the stack. The nitrogen is preferably entrapped in approximately the first 30 angstroms of the titanium layer.
