Abstract:
1. A film deposition method using a film deposition apparatus including a chamber into which a first reaction gas, which tends to be adsorbed onto hydroxyl radicals, and a second reaction gas capable of reacting with the first reaction gas are supplied, and a turntable provided in the chamber, a substrate provided with a concave portion being mounted on the turntable and a film of a reaction product of the first reaction gas and the second reaction gas being formed on the substrate, the method comprising: a step of controlling an adsorption distribution of the hydroxyl radicals in a depth direction in the concave portion of the substrate; a step of supplying the first reaction gas on the substrate onto which the hydroxyl radicals are adsorbed; and a step of supplying the second reaction gas on the substrate onto which the first reaction gas is adsorbed.
