Anodic nitridation of silicon and silicon dioxide

Anodic nitridation of Si wafers and SiO

films in an ammonia plasma was investigated. Compositions of the anodic nitride and the anodic nitrided-oxide films were analyzed with Auger electron spectroscopy and Rutherford backscattering techniques. The etching and oxidation behavior as well as the interfacial, electrical conduction, and charge trapping properties were studied.
