    摘要: The present disclosure provides a method of fabricating a semiconductor device that includes forming a high-k dielectric over a substrate, forming a first metal layer over the high-k dielectric, forming a second metal layer over the first metal layer, forming a first silicon layer over the second metal layer, implanting a plurality of ions into the first silicon layer and the second metal layer overlying a first region of the substrate, forming a second silicon layer over the first silicon layer, patterning a first gate structure over the first region and a second gate structure over a second region, performing an annealing process that causes the second metal layer to react with the first silicon layer to form a silicide layer in the first and second gate structures, respectively, and driving the ions toward an interface of the first metal layer and the high-k dielectric in the first gate structure.
