title = "A comparative study of gate stack material properties and reliability characterization in MOS transistors with optimal ALD Zirconia addition for hafina gate dielectric",
abstract = "In this work, we investigate the influence of incorporation Zirconia (ZrO 2) in gate dielectric HfO 2 on electrical properties and the reliability of nMOSFET for the 28nm technology node. Detailed film physical, chemical and optical properties of Hf 1-xZr xO 2 as a function of Zr content were studied using HRTEM, AR-XPS, spectroscopic ellipsometer. Compared to HfO 2, Hf 1-xZr xO 2 provides lower C-V hysteresis, V t shift (ΔV t) and higher Time to Failure (TTF) lifetimes are achieved with Zr incorporation in an ALD Hf 1-xZr xO 2/SiO2 gate stack. The improved reliability of the Hf 1-xZr xO 2 gate dielectric is attributed to the reduced charge trapping in the Hf 1-xZr xO 2 gate dielectric caused by the Zr incorporation.",
