Abstract
The electrical properties of silicon oxynitride (SiOxNy) films on Si deposited by low-pressure chemical vapour deposition have been studied. The effect of annealing on SiOxNy films on the basis of frequency analysis of capacitance-voltage and conductance-voltage characteristics of metal-SiOxNy-silicon capacitors in the frequency range 1-300kHz was determined. The post-deposition annealing results in a decrease of the concentrations of the positive dielectric charge and defects in the silicon substrate. The nature of the dielectric charges is discussed.
