Abstract :
The properties of traps at SiO2/Si and Si3N4/Si interfaces were examined and compared using deep level transient spectroscopy (DLTS). Small pulse DLTS was used to determine the effective electron capture cross-section of the interface states. Similar trends are found for both systems with the capture cross-section decreasing rapidly towards the band edge. The effective capture cross-section and energy level is also given for the Si≡Si3 defect at the Si3N4/Si interface.
