    摘要: A semiconductor device having an NMOS and a PMOS device formed thereon is provided. The NMOS device has additional spacers formed alongside the gate electrode to allow the silicide region to be formed farther away from the gate electrode. By placing the silicide region farther away from the gate electrode, the effects of the lateral encroachment of the silicide region under the spacers is reduced, particularly the leakage. A method of forming the semiconductor device may include forming a plurality of spacers alongside the gate electrodes of a PMOS and an NMOS device, and one or more implants may be performed to implant impurities into the source/drain regions of the PMOS and NMOS devices. One or more of the spacers alongside the gate electrode of the PMOS device may be selectively removed. Thereafter, the source/drain regions may be silicided.

    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.
