Abstract :
In this paper we report on the physical properties, such as thickness measurements and XPS depth profiles, and electrical properties of NO-grown gate dielectrics and compare them with films of similar thicknesses grown in N2O and O2. The interface state densities, interface state generation rate during electrical stress, charge trapping properties and stress induced leakage current are presented. In addition, electrical and physical properties of NO-annealed oxides which had an initial oxide and then were annealed in nitric oxide are included
