Abstract
A substrate processing method includes supplying processing gas from a plurality of gas holes formed along a longitudinal direction of an injector, which extends in a vertical direction along an inner wall surface of a processing container and is rotatable around a rotational axis extending in the vertical direction, to perform a predetermined process on a substrate accommodated in the processing container. The predetermined process includes a plurality of operations, and a supply direction of the processing gas is changed by rotating the injector in accordance with the operations.
