摘要: This study examines the effects of plasma-induced damage (PID) both on advanced SiO(2)/poly-gate and Hf-based high-k/dual metal-gates transistors processed with advanced complementary metal-oxide-semiconductor (CMOS) technology. In addition to the gate dielectric degradations, this study demonstrates the PID impacts on transistor reliability including the positive bias temperature instability (PBTI) of n-channel metal-oxide-semiconductor field-effect transistors (MOSFETs) and the negative bias temperature instability (NBTI) of p-channel MOSFETs with gate dielectric thickness scaling. This study shows that high-k/metal-gate transistors are more robust against PID than conventional SiO(2)/poly-gate transistors with similar physical thickness. Finally this study proposes a model that successfully explains the observed experimental trends in the presence of PID for advanced high-k/metal-gate CMOS technology. (C) 2010 Elsevier Ltd.
