Abstract

In one embodiment, a gate insulating layer, a conductive layer, and a metal layer are formed over a semiconductor substrate. An ion implantation region is formed in an interface of the conductive layer and the metal layer by performing an ion implantation process. A flash annealing process is performed on the ion-implanted semiconductor substrate. The metal layer, the conductive layer, and the gate insulating layer are patterned.
