Abstract
⺠We report the structural and electrical characteristics of nitrided hafnium oxide (HfO2) gate dielectrics. ⺠The nitridation process was conducted in the remote NH3 plasma at a low temperature under various radio-frequency powers. ⺠Significant decrease in the capacitance equivalent thickness, leakage current density, and interfacial layer thickness of the nitrided HfO2 gate dielectrics were achieved. ⺠The enhancement and decrease of the photoluminescence intensity from Si was also observed as a result of the hydrogen passivation and depassivation effects at the HfO2/Si interface.
