Abstract: A process for forming a titanium silicide local interconnect between electrodes separated by a dielectric insulator on an integrated circuit. A first layer of titanium is formed on the insulator, and a layer of silicon is formed on the titanium. The silicon layer is masked and etched to form a silicon strip connecting the electrodes, and an overlying second layer of titanium is formed over the silicon strip. The titanium and silicon are heated to form nonsilicidized titanium over a strip of titanium silicide, and the nonsilicidized titanium is removed.
