    摘要: In an embodiment a first silicon pattern and a second silicon pattern are formed on a substrate. The second silicon pattern has a lower top surface than the first silicon pattern. A first spacer covering a sidewall of the first silicon pattern is formed and a second spacer covering a sidewall of the second silicon pattern is formed. A silicide process is performed to silicidize the first silicon pattern and the second silicon pattern. Work functions of the first and second silicon patterns can be controlled and optimized by controlling the composition of the first and second silicon patterns.

    摘要: A method of fabricating a semiconductor device includes forming a preliminary gate pattern on a semiconductor substrate. The preliminary gate pattern includes a gate oxide pattern, a conductive pattern, and a sacrificial insulating pattern. The method further includes forming spacers on opposite sidewalls of the preliminary gate pattern, forming an interlayer dielectric pattern to expose the sacrificial insulating pattern, removing the sacrificial insulating pattern to form an opening to expose the conductive pattern, transforming the conductive pattern into a metal silicide layer and forming a metal barrier pattern along an inner profile of the opening and a metal conductive pattern to fill the opening including the metal barrier pattern. The metal silicide layer and the metal conductive pattern constitute a gate electrode.
