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 Web不同电介质的介电常数k 相差很大,真空的k 值为1,在所有材料中最低;空气的k值为1.0006;橡胶的k值为2.5~3.5;纯净水的k值为81。 工程上根据k值的不同,把电介质分为高k()电介质和低k(low-k)电介质两类。介电常数k >3.9 时,判定为high-k;而k≤3.9时则为low-k。 IBM将low-k标准规定为k≤2.8,业界大多以2.8 ... dark brown oversized blazer
