    摘要: The present invention provides a method for manufacturing a semiconductor device and a method for manufacturing an integrated circuit including the semiconductor device. The method for manufacturing the semiconductor device (100), among other possible steps, includes forming a polysilicon gate electrode over a substrate (110) and forming source/drain regions (170) in the substrate (110) proximate the polysilicon gate electrode. The method further includes forming a blocking layer (180) over the source/drain regions (170), the blocking layer (180) comprising a metal silicide, and siliciding the polysilicon gate electrode to form a silicided gate electrode (150).

    摘要: The present invention provides a method for manufacturing a semiconductor device and a method for manufacturing an integrated circuit. The method for manufacturing the semiconductor device, among other steps, includes providing a capped polysilicon gate electrode (290) over a substrate (210), the capped polysilicon gate electrode (290) including a buffer layer (260) located between a polysilicon gate electrode layer (250) and a protective layer (270). The method further includes forming source/drain regions (710) in the substrate (210) proximate the capped polysilicon gate electrode (290), removing the protective layer (270) and the buffer layer (260), and siliciding the polysilicon gate electrode layer (250) to form a silicided gate electrode (1110).

    摘要: Semiconductor components are often fabricated that include a nickel silicide layer, e.g., as part of a gate electrode in a transistor component, which may be formed by forming a layer of nickel on a silicon-containing area of the semiconductor substrate, followed by thermally annealing the semiconductor substrate to produce a nickel silicide. However, nickel may tend to diffuse into silicon during the thermal anneal, and may form crystals that undesirably increase the sheet resistance in the transistor. Carbon may be placed with the nickel to serve as a diffusion suppressant and/or to prevent nickel crystal formation during thermal annealing. Methods are disclosed for utilizing this technique, as well as semiconductor components formed in accordance with this technique.
