    摘要: A semiconductor process includes the following steps. An interdielectric layer is formed on a substrate and the interdielectric layer has a first recess and a second recess. A metal layer is formed to cover the surface of the interdielectric layer, the first recess and the second recess. Partially fills a sacrificed material into the first recess and the second recess so that a portion of the metal layer in each of the recesses is respectively covered. The uncovered metal layer in each of the recesses is removed. The sacrificed material is removed. An etching process is performed to remove the remaining metal layer in the first recess and reserve the remaining metal layer in the second recess.

    摘要: A salicide process is described. A substrate having thereon an insulating layer and a silicon-based region is provided. A nickel-containing metal layer is formed on the substrate. A first anneal process is performed to form a nickel-rich silicide layer on the silicon-based region. The remaining nickel-containing metal layer is stripped. A thermal recovery process is performed at a temperature of 150-250° C. for a period longer than 5 minutes. A second anneal process is performed to change the phase of the nickel-rich silicide layer and form a low-resistivity mononickel silicide layer.
