Poly-SiGe- and poly-Si-gated N/PMOS devices with physical channel lengths down to 0.1μm and gate oxide thicknesses down to 25 angstrom were fabricated. Device performance and reliability were characterized. The poly-SiGe-gated NMOS and PMOS devices provide superior current drive due to less gate-depletion effect and higher inversion hole mobility in poly-SiGe-gated devices. In addition, gate oxide integrity in poly-SiGe-gated MOSFET is as good as poly-Si-gated device. Poly-SiGe-gated PMOSFET has better reliability than poly-Si-gated PMOSFET due to reduction of boron penetration.
