- the temperature of the portion where the tetrachloride titanium and ammonia are mixed in the supply pipe for the film forming gas is usually in the range of about 200 ° C to 400 ° C. In such a temperature range, the reaction product is considered to be gaseous, and the reaction product itself is unlikely to accumulate in the piping.
- the concentration of ammonia in the film-forming gas is decreased, and it is considered that the gas phase reaction between the tetrasalt titanium and ammonia is suppressed.
- ammonia is transported to the surface of the glass substrate as a reaction product with salt and hydrogen. Since the temperature of the glass substrate surface is about 600 to 1000 ° C., it is considered that the reaction product is decomposed and molecular ammonia is formed.
- the formed ammonia is considered to react with tetra-salt / titanium contained in the film-forming gas to form a thin film containing nitrogen and titanium.
