摘要

A direct-current voltage-voltage (DCVV) technique for thenmeasurement of stress-generated interface traps in sub-micronnmetal-oxide-semiconductor transistors (MOSTs) is demonstrated. Thisnmethod uses the source-bulk-drain structure of a sub-micron MOST as anneffective lateral bipolar transistor when the channel region is out ofninversion under the control of the gate voltage Vgb. Thenemitter injects the minority carriers into the base region and thencollector is open. The Vcb versus Vgb spectrum cannbe explained quantitatively using the extended Ebers-Moll equations andninterface trap Shockley-Read-Hall (SRH) recombination. A singleneffective interface trap at the source or drain side could be detected,nand interface traps at the source side can be separated from those atnthe drain side by the new method
