    摘要: A semiconductor structure includes a first silicon-containing layer comprising an element selected from the group consisting essentially of carbon and germanium wherein the silicon-containing layer has a first atomic percentage of the element to the element and silicon, a second silicon-containing layer comprising the element over the first silicon-containing layer, and a silicide layer on the second silicon-containing layer. The element in the second silicon-containing layer has a second atomic percentage of the element to the element and silicon, wherein the second atomic percentage is substantially lower than the first atomic percentage.

    摘要: A method for forming nickel silicide includes degassing a semiconductor substrate that includes a silicon surface. After the degassing operation, the substrate is cooled prior to a metal deposition process, during a metal deposition process, or both. The cooling suppresses the temperature of the substrate to a temperature less than the temperature required for the formation of nickel silicide. Nickel diffusion is minimized during the deposition process. After deposition, an annealing process is used to urge the formation of a uniform silicide film. In various embodiments, the metal film may include a binary phase alloy containing nickel and a further element.
