ScholarBank@NUS Repository. https://doi.org/10.1109/TED.2008.2010585 | Abstract: | A novel recovery-free interface-trap measurement method is presented in detail. This method is the modification of the conventional charge pumping (CP) by extending the pulse low level to the stress-bias and minimizing the pulse high-level duty cycle to suppress the recovery effect. The method is applied to study the negative-bias temperature instability in p-MOSFETs. As compared with the conventional CP, a much larger interface-trap generation under stress is observed by the new method. A power law time dependence (∼ tn of interface-trap generation is observed. The index n is less than that derived from conventional CP and increases with temperature, demonstrating a dispersive process involved in the trap generation dynamics. © 2009 IEEE. | Source Title: | IEEE Transactions on Electron Devices | URI: | http://scholarbank.nus.edu.sg/handle/10635/81883 | ISSN: | 00189383 | DOI: | 10.1109/TED.2008.2010585 |
