New stress inducing technique of epitaxial si on recessed S/D fabricated in substrate strained-si of [100]channel on rotated wafers
For the first time, a novel CMOSFET structure in substrate strained-Si of lang100rang-channel on rotated wafers is presented. Low Ge concentration (10%) of SiGe layer is used in order to suppress the Vth shift and the mobility reduction caused by high channel doping. We applied Si selective epitaxial growth on recessed S/D region in SiGe layer, which is effective to induce high tensile stress and reduce S/D resistance. In strained Si NMOS, 15% performance improvement is achieved. Moreover, additive stress by using tensile CESL can further improve the drive current. In strained Si PMOS, 25% performance improvement is achieved in both narrow and wide channel device
