Paper Abstract

This paper studies the charge characteristics and the interface trapping of new-type thin rapid thermal nitrided SiOxNy film (RTNF) and thin reoxidized nitrided SiOxNy film by the photo I-V method and the avalanche hot-electron injection technique. The research results give the bulk charge density and its distribution centroid position of thin RTNF and thin conventional SiO2 film. The reoxidation processing after rapid thermal nitridation reduced effectively the densities of bulk electron trapping and interface state in the RTNF. A physical model explanation of weakly-present 'N' form change for flatband voltage shift with avalanche injection dose also was presented. The change relationship of energy distribution for interface state density with injection dose was obtained. The theoretical analyses and discussions of these research results are included in this paper.
