Abstract

According to the 45 nm BEOL technology node, we demonstrated that a homogeneous interlayer dielectric with dielectric constant of 2.25 has a substantial advantage in terms of RC delay reduction compared to other potential architectures such as hybrid and tri-level dielectrics. Combination of the homogeneous interlayer dielectric and ultra-thinned barrier metal lowered the RC delay to 86 % compared to that listed in the ITRS 2006 update.
45nm BEOL技术RC延迟降低策略
根据45 nm BEOL技术节点,我们证明了介电常数为2.25的均匀层间介电材料与其他潜在的结构(如混合和三能级介电材料)相比,在RC延迟减少方面具有实质性的优势。与ITRS 2006更新中列出的相比,均匀层间介质和超薄屏障金属的组合将RC延迟降低到86%。
