説明

Hydrogen-free silicon oxynitride was deposited at 300℃ through the reaction of Si from a solid source and neutral oxygen and nitrogen species activated in remote ECR plasma. The IR absorption measurement clearly showed that the composition of oxygen and nitrogen in the film was controlled by simply varying the flow ratio of the source gases of O_2 and N_2.Oxynitride films without internal stress could be trellised by adjusting the film composition of oxygen and nitrogen. The deposited film had high resistivity and breakdown field, and the interface state density between the film and Si was in the lower range of 10^<10>cm^<-2>eV^<-1>, which were sufficient for device application.
