Abstract :
The paper presents a study of localized charge injection through the gate oxide in MOS transistors with 4.5-13 nm thick oxides and its application for device diagnostics. The injection, localized over a gate/drain overlap, is investigated in a high-field GIDL (Gate-Induced Drain Leakage) regime in both NMOS and PMOS devices and is found to be a suitable diagnostic tool for monitoring one of the many process-dependent parameters-the thickness of the gate oxide at the gate edge. Correlation between edge oxide thickening, plasma edge damage, and the performance and reliability of CMOS devices is presented.
