Abstract:
A method of manufacturing a semiconductor device including at least two metal-based, in-laid gate electrodes of different composition, comprising the sequential steps of:(a) providing a semiconductor substrate; (b) forming at least first and second spaced-apart active device precursor regions on or within said semiconductor substrate; (c) forming a first metal-based, in-laid gate electrode in electrical contact with said first active device precursor region, said first metal-based, in-laid gate electrode comprised of a first metal; and (d) forming a second metal-based, in-laid gate electrode in electrical contact with said second active device precursor region, said second metal-based, in-laid gate electrode comprised of an alloy of said first metal with a second metal or semi-metal or of an electrically conductive silicide of said first metal.
