As the integration density and capacitance of semiconductor devices have increased, high-dielectric (High-k) materials have attracted considerable attention. We investigated the dependence of threshold voltage (Vth) characteristics of the High-k/Metal Gate MOSFET fabricated with 65 nm CMOS process on the temperature, in comparison to conventional SiON/Poly-Si Gate MOSFET. Two aspects including the Fermi level and the channel mobility in MOSFET are discussed in details. Furthermore, the influence of threshold voltage characteristics of the High-k/Metal Gate MOSFET on the logic threshold voltage (Vth-inv) of CMOS inverter is reported in this paper.
