摘要

We investigated the effects of thermal annealing on both the conduction current and the paramagnetic K~0 centers induced by exposing LPCVD silicon nitride films to 4.9 eV ultraviolet (UV) illumination. The current component induced by UV illumination decayed by the thermal annealing at 150 and 240 ℃. UV illumination following the 240 ℃ annealing induced the current increase once again. The UV-induced current increase is a reversible phenomenon. The current densities after UV exposure and after the subsequent thermal annealing were obviously dependent on the density of the UV-induced paramagnetic defects. We proposed that the UV-induced paramagnetic defects acted as generation centers of electron-hole pairs in the nitride films and the creation of the paramagnetic defects is responsible for the UV-induced current increase.
