Abstract

The physical and electrical properties of nitrided Hf-silicate films, incorporated by NO gas annealing, were investigated by XPS, NEXAFS, TEM and C-V measurement. We confirmed the nitrogen incorporation during NO gas annealing treatment effectively enhances the thermal stability of Hf-silicate. The suppression of phase separation was observed in Hf-silicate films with high nitrogen contents. The negative shift of threshold voltage is caused by the incorporation of nitrogen in the hafnium silicate films.
