    摘要: The present invention provides methods of forming cobalt layers on a structure comprising forming a preliminary cobalt layer on a semiconductor substrate by introducing an organic metal precursor onto the semiconductor substrate and treating a surface of the preliminary cobalt layer under an atmosphere of a hydrogen-containing gas to remove impurities contained in the preliminary cobalt layer. Compositions of cobalt layers are also provided. Further provided are semiconductor devices comprising cobalt layers provided herein.

    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.
