    The unwanted high threshold voltage (V-t) is the major challenge for metal-gate/high-kappa CMOs especially at small equivalent-oxide-thickness (EOT). We have investigated the high V-t issue that is due to flat-band voltage (V-fb) roll-off at smaller EOT. A mechanism of charged oxygen vacancies formed by interface reaction was proposed to explain the V-fb roll-off effect. This interface reaction can be decreased by inserting a thin interfacial SiON and using novel low temperature process. The self-aligned and gate-first metal-gate/high-kappa CMCSFETs using these methods have achieved low V-t and good control of V-fb roll-off at small 0.6-1.2 nm EOT.

    We have demonstrated high-performance metal-gate/high-k Ytterbiuni/LaAlO3 low-temperature poly-Si (LTPS) thin film transistors (TFTs) that have both high drive current capability and high voltage operation. The high drive current is due to the combined effect of low work-function Ytterbium metal gate and high gate capacitance by high-k LaAlO3 dielectric. The high breakdown voltage is also due to the high-k LaAlO3 dielectric to give larger physical thickness at the same equivalent oxide thickness (EOT). The good reliability and full process compatibility are the other important merits for Ytterbium/LaAlO3 device.
