Apparatus and method for treating substrate
A method for treating a substrate includes a substrate treating step of treating the substrate by dispensing a treating liquid onto the substrate supported on a support plate in a processing space of a processing vessel and a vessel cleaning step of cleaning the processing vessel by dispensing a cleaning solution onto a jig supported on the rotating support plate. In the vessel cleaning step, the jig is located such that the center of the jig is offset from the center of the support plate.
1. A method for treating a substrate, the method comprising:
a substrate treating step of treating the substrate by dispensing a treating liquid onto the substrate supported on a support plate in a processing space of a processing vessel; and
a vessel cleaning step of cleaning the processing vessel by dispensing a cleaning solution onto a jig supported on the rotating support plate,
wherein in the vessel cleaning step, the jig is located such that the center of the jig is offset from the center of the support plate.
2. The method of claim 1 , wherein a relative height between the support plate and the processing vessel is varied in the vessel cleaning step.
3. The method of claim 2 , wherein the height of the processing vessel is varied by a motor.
4. The method of claim 1 , wherein the jig has the same size as the substrate.
