Abstract:
The trade-off between Tinv scaling and carrier mobility (mu) degradation in deeply scaled HK/MG nMOSFETs has been investigated based on experimental results. Ion, components are analyzed in terms of NS, vinj and SCE in Lg= 25 nm devices for the first time. As a result, it is clarified that the aggressive Tinv scaling can achieve the performance improvement even if mu degradation occurs in some degree, because mu impact decreases with Lg and Tinv scaling impact becomes strong. Furthermore, we have introduced the effective Tinv scaling (novel SiON) process and demonstrated its excellent device performance (Ion 1 mA/mum @Ioff=100 nA/mum, Lg 25 nm, Vdd=LOV, Avt=1.8 mV mum, Tinv 1.13 nm, without any performance booster technology).
