The recent industry wide investigation of incorporating various elemental dopant species into HfO2 to achieve higher-k gate dielectric alloy materials in order to maintain the rapid pace of scaling according to Moore's Law has been expanded to include enhancement of the SiO/HfO interface dipole to tune the effective work function (EWF) of n and p-type gate electrodes.
