Web（1） 首先，肯定要比较挑选用哪种high-k材料吧？ 是Al2O3，是HfO2，还是TiO2？ 是不是要从 材料特性 开始研究和对比？ band gap？ conduction band offset？ 长在Si channel … The term high-κ dielectric refers to a material with a high dielectric constant (κ, kappa), as compared to silicon dioxide. High-κ dielectrics are used in semiconductor manufacturing processes where they are usually used to replace a silicon dioxide gate dielectric or another dielectric layer of a … Ver mais Silicon dioxide (SiO2) has been used as a gate oxide material for decades. As metal–oxide–semiconductor field-effect transistors (MOSFETs) have decreased in size, the thickness of the silicon dioxide gate dielectric has … Ver mais • Electronics portal • Low-κ dielectric • Silicon–germanium • Silicon on insulator Ver mais • Review article by Wilk et al. in the Journal of Applied Physics • Houssa, M. (Ed.) (2003) High-k Dielectrics Institute of Physics Ver mais Replacing the silicon dioxide gate dielectric with another material adds complexity to the manufacturing process. Silicon dioxide can be formed by oxidizing the underlying … Ver mais Industry has employed oxynitride gate dielectrics since the 1990s, wherein a conventionally formed silicon oxide dielectric is infused with a small amount of nitrogen. The nitride content subtly raises the dielectric constant and is thought to offer other … Ver mais
