Patent ID: 11913115

Abstract:
A substrate processing apparatus including: a processing container; an injector provided inside the processing container to have a shape extending in a longitudinal direction and configured to supply a processing gas; a holder fixed to the injector; a windmill fixed to the holder; a first driving-gas supply part configured to supply a driving-gas that rotates the windmill in a first direction; a second driving-gas supply part configured to supply the driving-gas that rotates the windmill in a second direction opposite the first direction; and a driving-gas controller configured to control the supply of the driving-gas from the first driving-gas supply part and the second driving-gas supply part. The injector is rotated about the longitudinal direction corresponding to a rotational axis by rotating the windmill through the supply of the driving-gas from at least one of the first and second driving-gas supply parts under the control of the driving-gas controller.
