Abstract :
NBTI degradation mechanism is studied for 0.18μm pMOSFETs. Degradation on saturation and linear mode of operations are investigated respectively. To address the controlled delay in between stress cycles which account for the recovery effect, an optimized ID-VG sweep is devised in this work. The optimized ID-VG sweep is found to be able to reduce the recovery effect and it is easily to be implemented in typical DC parametric production tester in wafer fabrication manufacturing environment.
