WebApr 6, 2024 · This time dependence is not properly accounted for in the existing test methods for assessing high-temperature gate-bias (HTGB) effects, which allow temporary removal of bias during cool down and significant un-biased delay (up to 96 hours) before the post-stress measurements are performed. ... This difficulty can be overcome by … WebBoth methods give consistent results: at room temperature, the positive gate-bias stress leads to a positive V T shift, whereas the negative-gate bias stress results in negative V T shift...
