    摘要: A method of fabricating a Schottky field effect transistor is provided that includes providing a substrate having at least a first semiconductor layer overlying a dielectric layer, wherein the first semiconductor layer has a thickness of less than 10.0 nm. A gate structure is formed directly on the first semiconductor layer. A raised semiconductor material is selectively formed on the first semiconductor layer adjacent to the gate structure. The raised semiconductor material is converted into Schottky source and drain regions composed of a metal semiconductor alloy. A non-reacted semiconductor material is present between the Schottky source and drain regions and the dielectric layer.

    摘要: An interconnect structure which includes a plating seed layer that has enhanced conductive material, preferably, Cu, diffusion properties is provided that eliminates the need for utilizing separate diffusion and seed layers. Specifically, the present invention provides an oxygen/nitrogen transition region within a plating seed layer for interconnect metal diffusion enhancement. The plating seed layer may include Ru, Ir or alloys thereof, and the interconnect conductive material may include Cu, Al, AlCu, W, Ag, Au and the like. Preferably, the interconnect conductive material is Cu or AlCu. In more specific terms, the present invention provides a single seeding layer which includes an oxygen/nitrogen transition region sandwiched between top and bottom seed regions. The presence of the oxygen/nitrogen transition region within the plating seed layer dramatically enhances the diffusion barrier resistance of the plating seed.

    摘要: A method forms an integrated circuit structure. The method patterns a protective layer over a first-type field effect transistor and removes a stress liner from above a second-type field effect transistors. Then, the method removes a first-type silicide layer from source and drain regions of the second-type field effect transistor, but leaves at least a portion of the first-type silicide layer on the gate conductor of the second-type field effect transistor. The method forms a second-type silicide layer on the gate conductor and the source and drain regions of the second-type field effect transistor. The second-type silicide layer that is formed is different than the first-type silicide layer. For example, the first-type silicide layer and the second-type silicide layer can comprise different materials, different thicknesses, different crystal orientations, and/or different chemical phases, etc.

    摘要: A method for forming a metal-semiconductor alloy layer uses particular thermal annealing conditions to provide a stress free metal-semiconductor alloy layer through interdiffusion of a buried semiconductor material layer and a metal-semiconductor alloy forming metal layer that contacts the buried semiconductor material layer within an aperture through a capping layer beneath which is buried the semiconductor material layer. A resulting semiconductor structure includes the metal-semiconductor alloy layer that further includes an interconnect portion beneath the capping layer and a contiguous via portion that penetrates at least partially through the capping layer. Such a metal-semiconductor alloy layer may be located interposed between a substrate and a semiconductor device having an active doped region.
