Spectroscopic analysis of stress-induced defects in thin silicon oxide films
This paper describes a significant feature of stress-induced defects on the basis of the steady state SILC component and transient characteristics. Fourier transformation of the discharging current strongly suggests, in contrast to past results, that most defects share virtually the same energy level. Assuming that the defect level is 2.1 eV below the SiO2 conduction band bottom, simple Monte Carlo simulations show the defects lie 1.2 nm from the substrate.
