Abstract

In this work, an electron spin resonance study of NH₃-nitrided, N₂O-nitrided, and N₂O-grown oxides yields information relating the process history, point defect structure, and electrical behavior. NH₃-nitridation is responsible for the introduction of bridging nitrogen centers, high capture cross section neutral electron traps, while N₂O-processed dielectrics never exhibit these defects. In addition, structural changes at the interface due to nitridation result in observable differences in the interfacial defects.
