Radiofrequency glow discharges, operating under various conditions, have been used to deposit hydrogenated and fluorinated silicon nitride (a-Si,N:H,F) from SiF4-N2-H2 gas mixtures. The effect of the feeding mixture composition has been investigated in order to establish the optimum deposition conditions for stable silicon nitride. High H2-dilution of the feeding mixture has been found to produce transparent (Eg>5.6eV) and stoichiometric (N/Si=1.3) films.

Abstract
Radiofrequency glow discharges, operating under various conditions, have been used to deposit hydrogenated and fluorinated silicon nitride (a-Si,N:H,F) from SiF4-N2-H2 gas mixtures. The effect of the feeding mixture composition has been investigated in order to establish the optimum deposition conditions for stable silicon nitride. High H2-dilution of the feeding mixture has been found to produce transparent (Eg>5.6eV) and stoichiometric (N/Si=1.3) films.File in questo prodotto:
