Semiconductor devices having fully metal silicided gate electrodes, and methods for making the same, are disclosed. The devices have shallow S/D extensions with depths of less than about 500 Å. The methods for making the subject semiconductor devices employ diffusion of dopant from metal suicides to form shallow S/D extensions, followed by high energy implantation and activation, and metal silicidation to form S/D junctions having metal silicide connect regions and a fully metal silicided electrode. |
