Abstract(in English) | SiNx thin-film deposition by catalytic CVD (Cat-CVD) method is expected to realize a 1ow-damage plasmaldss process in fabrication of passivation fi1ms for compound-semiconductor devices etc. A tungsten wire was used as a catalyzer to decompose SiH_4 and NH_3 gases, SiNx thin films were deposited on GaAs substrates, and the uniformity of well-stoichiometric (Si_3N_4) films, with about 2.0 in refractive index, was evaluated by ellipsometry. It was found that the film thickness decreases about 15% circumferentially from the center, but the uniformity of refractive index keeps within about ±2.5% in a 4-inch wafer even though Si and N are supplied seperately. It is confirmed that preparation of device-quality SiNx thin films on large substrates can be achieved by Cat-CVD method. |
