Abstract :
This paper report on the reliability properties of microwave-plasma deposited ultrathin high-k gate dielectric (ZrO2 ) films on strained-Si/SiGe layers. Stress induced leakage current; trap centroid and charge trapping behavior under constant current and voltage stressing in both polarities have been studied
