Claim 5:
6. The manufacturing method for the silicon nitride thin film according to claim 1, wherein comprising steps of:
providing the silane precursor into the atomic layer deposition apparatus for 0.02 seconds, and allowing the silane precursor to remain in the atomic deposition apparatus for 0.03 seconds;
providing the inert gas into the atomic layer deposition apparatus for 5 seconds for the first time;
providing the nitrogen supplying precursor into the atomic layer deposition apparatus for 5 seconds, and allowing the nitrogen supplying precursor to remain in the atomic deposition apparatus for 20 seconds;
providing the inert gas into the atomic layer deposition apparatus for 20 seconds for the second time; and
repeating for 500 times the steps of providing the silane precursor, providing the inert gas for the first time, providing the nitrogen supplying precursor and providing the inert gas for the second time to form the each of the first silicon nitride layer, the second silicon nitride layer, and the third silicon nitride layer.
