摘要
Using strained SiGe on Si, the threshold voltage of high K PMOS devices is reduced by as much as 300mV. The 80nm devices exhibit excellent short channel characteristics such as DIBL and GIDL. For the first time a dual channel scheme using standard activation anneal temperature is applied that allows La2O3 capping in NMOS and SiGe channel in PMOS to achieve acceptable values of threshold voltage for high K and metal gates for 32nm node and beyond.
