Analysis of systematic and random variation of gate-induced drain leakage in silicon-germanium channel pFET

Abstract

Variability in the transistor parameters play a significant role in CMOS scaling to nanometer feature sizes. New channel materials such as silicon-germanium for pFET at 32nm and beyond are useful because of higher mobility and lower threshold voltage. However, gate-induced drain leakage (GIDL) is dominant in the total leakage and the use of germanium (Ge… (More)
