Summary: | 碩士 === 銘傳大學 === 電子工程學系碩士班 === 106 === In this study, we do the time-dependent dielectric breakdown(TDDB) for voltage
and time to relationship, and negative bias temperature instability(NBTI) in Ge
p-MOSFETs with HfO2 gate dielectric were examined. Samples with annealing at 500℃
and non-annealing were comparison. The higher temperature and the higher
electrical field in degradation, the worse NBTI effect. The measurement results show
threshold voltage(Vth)、the maximum transconductance(GmMAX)、the minimal
subthreshold swing(SS)、 saturation-region drain current(Idsat)、linear-region drain
current(Idlin) were degradation of the time to dependent. In NBTI lifetime extraction
from the 10% degradation,the device of annealing at 500℃ was better than
non-annealing. We got the △Nit and △Not from I-V curve shift.
