A new experimental technique namely the linear cofactor difference sub-threshold voltage method is presented in this paper for extraction of the MOSFET interface traps induced by the gate oxide stress test and verified on N-MOSFETs.The basic principle of this technique is introduced and the experimental realization is elucidated in details.It is shown that this method enables reliable extraction of the increased interface traps with a rise of the accumulated gate oxide stress test time to be obtained and that its validity is also verified by the extraction experiments on an n-channel MOSFET device.This method will be a new tool in characterizing and predicting reliability and lifetime of MOFSTs.
