    摘要: Both high performance and low leakage current devices can be formed on a single wafer without significant additional processing steps by the formation of an ultra-thin gate dielectric and a high-permittivity gate dielectric, respectively, in regions wherein switching speed and low leakage current, respectively, are desired. Logic and embedded memory regions can be performance optimized on the same integrated circuit.

    摘要: A method of forming a strained silicon layer on a relaxed, low defect density semiconductor alloy layer such as SiGe, has been developed. In a first embodiment of this invention the relaxed, low density SiGe layer is epitaxially grown on an silicon layer which in turn is located on an underlying SiGe layer. During the epitaxial growth of the overlying SiGe layer defects are formed in the underlying silicon layer resulting in the desired, relaxation, and decreased defect density for the SiGe layer. A second embodiment features an anneal procedure performed during growth of the relaxed SiGe layer, resulting in additional relaxation and decreased defect density, while a third embodiment features an anneal procedure performed to the underlying silicon layer prior to epitaxial growth of the relaxed SiGe layer, again allowing optimized relaxation and defect density to be realized for the SiGe layer. The ability to obtain a strained silicon layer on a relaxed, low defect density SiGe layer, allows devices with enhanced carrier mobility to be formed in the surface of the strained silicon layer, with decreased risk of leakage due the presence of the underlying, relaxed, low defect density SiGe layer.

    摘要: A method of forming a tensile or compressive strained channel region for a semiconductor device, such as a MOSFET device, allowing improved carrier transport properties and increased device performance to be realized, has been developed. The method features the epitaxial growth of a semiconductor layer such as silicon, or silicon-germanium, with the incorporation of atoms such as carbon. The silicon-germanium-carbon channel layer, under biaxial tensile or compressive strain, is then overlaid with an optional silicon capping layer, used to accommodate the overlying, thermally grown silicon dioxide gate insulator layer, of the MOSFET device.
