摘要
MOSCAPs and MOSFETs of a single-layer thin HfO2 gate dielectric with n+ polysilicon gate were fabricated and characterized. Polysilicon process was optimized such that leakage current and equivalent oxide thickness of HfO2 remained low. Excellent C-V properties (e.g. low Dit and frequency dispersion) and reliability characteristics were obtained. Reasonable MOSFET quality was also demonstrated.
