Classification: CPC H  B | IPC B  H

Claim 7:
8. The substrate processing apparatus of claim 5, wherein, when an angle formed between a straight line, which connects a foot of a perpendicular line drawn from the ejection port of the processing liquid nozzle to a surface of the substrate and the liquid arrival point, and a straight line connecting the ejection port of the processing liquid nozzle to the liquid arrival point is an angle φ,
the processing liquid nozzle is installed such that the angle φ becomes a first angle smaller than 90 degrees when the gas is not ejected from the gas nozzle, and
the gas nozzle is installed to change the direction of the processing liquid ejected from the processing liquid nozzle such that the angle φ becomes a second angle closer to 0 degrees than the first angle when the gas is ejected from the gas nozzle.
