Classification: CPC H  C | IPC C  H

Claim 0:
1. A method of manufacturing a semiconductor structure, comprising:
providing a base; and
forming a silicon nitride film layer on the base by an atomic layer deposition process; wherein the atomic layer deposition process comprises multiple cyclic deposition steps; in each of the cyclic deposition steps, a silicon source gas and a nitrogen source gas are provided to a surface of the base;
wherein, before each of the cyclic deposition steps, the method of manufacturing a semiconductor structure further comprises a repair step; in the repair step, a repair gas is provided to the surface of the base, and the repair gas is a hydrogen-containing repair gas; the repair gas comprises a polar molecule for repairing the surface of the base that is damaged.
