Abstract
In a substrate processing apparatus, a cup part is moved in an up-down direction to cause a cup exhaust port to selectively overlap a first chamber exhaust port or a second chamber exhaust port. In the state in which the cup exhaust port overlaps the first chamber exhaust port, gas in the cup part is discharged through the cup exhaust port and the first chamber exhaust port by a first exhaust mechanism. In the state in which the cup exhaust port overlaps the second chamber exhaust port, the gas in the cup part is discharged through the cup exhaust port and the second chamber exhaust port by a second exhaust mechanism. In this way, an exhaust mechanism for exhausting gas from the cup part can be easily switched between the first exhaust mechanism and the second exhaust mechanism.
