Silicon oxynitride films have been grown by a photochemical vapor deposition process utilizing VUV light of a deuterium lamp from a gas mixture of Si2H6, NH3, and NO2 at the substrate temperature of about 330 °C. The deposition rate of the film varied with NO2 flow rate and also with the excitation light spectrum which was varied by a low-pass filter of a synthetic or fused silica plate. The composition of the films was sensitive to the NO2 flow rate which was smaller than that of NH3 by a factor of 103.
