Patent ID: 8529707

Claim:
A liquid processing method, comprising: supplying chemicals to a bottom surface of a target substrate while holding the target substrate horizontally on a substrate holding unit and rotating the target substrate around a vertical shaft of the substrate holding unit at a first rotation speed and allowing the chemicals to flow onto a top surface of the target substrate through a peripheral cross section of the target substrate; throwing off the chemicals by halting the supply of the chemicals and rotating the target substrate at a second rotation speed higher than the first rotation speed; and supplying a rinse liquid to the bottom surface of the target substrate while rotating the target substrate at a third rotation speed lower than the first rotation speed and allowing the rinse liquid to flow onto the top surface of the target substrate through the peripheral cross section of the target substrate, wherein the supplying of the rinse liquid to the target substrate includes a period of supplying the rinse liquid while rotating the target substrate at a fourth rotation speed higher than the second rotation speed before rotating the target substrate at the third rotation speed.
