Abstract :
For better understanding of SiGe tunnel field-effect transistors (TFETs) and its band-to-band tunneling (BTBT) mechanism, gate-induced-drain-leakage (GIDL) of MOSFETs was analyzed. GIDL were measured on Si/SiGe/SOI quantum-well p-MOSFETs. The numerical model of the analysis was elaborated and the critical exponential parameters were successfully extracted for strained SiGe with varying Ge content and strain.
