摘要
The time-dependence of the gate voltage [V-G(t)] during constant current stress of MOS capacitors with a 2.4 nm gate oxide layer after the occurrence of soft breakdown is analysed. It is shown that the fluctuations observed in V-G(t) are non-Gaussian and can be fitted by Levy distributions. The long-range correlations in V-G(t) are investigated by using the Detrended Fluctuation Analysis (DFA). From this analysis, it is found that long-range antipersistant correlations exist in the gate voltage signal. These results can be qualitatively explained by a dynamic percolation model, taking into account the trapping-detrapping of electrons within the percolation cluster formed after the occurrence of soft breakdown.
