摘要
Gate-first integration of band-edge (BE) high-kappa/metal gate nFET devices with dual stress liners and silicon-on-insulator substrates for the 45nm node and beyond is presented. We show the first reported demonstration of improved short channel control with high-kappa/metal gates (HK/MG) enabled by the thinnest T-inv (< 12 angstrom) for BE nFET devices to-date, consistent with simulations showing the need for < 14 angstrom Tin, at Lgate < 35nm. We report the highest BE HK/MG nFET Idsat values at 1.0V operation. We also show for the first time BE high-kappa/metal gate pFET's fabricated with gate-first high thermal budget processing with thin Tin, (< 13A) and low Vts appropriate for pFET devices. The reliability in these devices was found to be consistent with technology requirements. Integration of high-kappa/metal gate nFET's into CMOS devices yielded large SRAM arrays.
