    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.
