    摘要: A method of smoothening a surface of a semiconductor structure comprises exposing the surface of the semiconductor structure to a reactant. A chemical reaction between a material of the semiconductor structure and the reactant is performed. In the chemical reaction, a layer of a reaction product is formed on at least a portion of the surface of the semiconductor structure. The layer of the reaction product is selectively and completely removed.

    摘要: The present invention provides a technique for forming a metal silicide, such as a cobalt disilicide, even at extremely scaled device dimensions without unduly degrading the film integrity of the metal silicide. To this end, an ion implantation may be performed, advantageously with silicon, prior to a final anneal cycle, thereby correspondingly modifying the grain structure of the precursor of the metal silicide.
