    摘要: A method for improving channel carrier mobility in ultra-thin Silicon-on-oxide (UTSOI) FET devices by integrating an embedded pFET SiGe extension with raised source/drain regions. The method includes selectively growing embedded SiGe (eSiGe) extensions in pFET regions and forming strain-free raised Si or SiGe source/drain (RSD) regions on CMOS. The eSiGe extension regions enhance hole mobility in the pFET channels and reduce resistance in the pFET extensions. The strain-free raised source/drain regions reduce contact resistance in both UTSOI pFETs and nFETs.

    摘要: A method is provided to fabricate a semiconductor device, where the method includes providing a substrate comprised of crystalline silicon; implanting a ground plane in the crystalline silicon so as to be adjacent to a surface of the substrate, the ground plane being implanted to exhibit a desired super-steep retrograde well (SSRW) implant doping profile; annealing implant damage using a substantially diffusionless thermal annealing to maintain the desired super-steep retrograde well implant doping profile in the crystalline silicon and, prior to performing a shallow trench isolation process, depositing a silicon cap layer over the surface of the substrate. The substrate may be a bulk Si substrate or a Si-on-insulator substrate. The method accommodates the use of an oxynitride gate stack structure or a high dielectric constant oxide/metal (high-K/metal) gate stack structure. The various thermal processes used during fabrication are selected/controlled so as to maintain the desired super-steep retrograde well implant doping profile in the crystalline silicon.
