Abstract:
1. A substrate processing method comprising the steps of: rotating a substrate; reserving a process liquid in a process liquid reservoir in a predetermined amount sufficient to form a liquid film covering the whole area of a principal face of the substrate; forming the liquid film covering the whole area of the principal face of the substrate by supplying process liquid reserved by the process liquid reservoir toward the principal face of the substrate being rotated; wherein the liquid film forming step includes the steps of supplying pressurized gas to pressurize said process liquid reservoir and then using said pressurized gas to push out the process liquid reserved in the process liquid reservoir, and thereby supply said process liquid to said substrate in a single burst; and after the liquid film forming step, dispensing the process liquid from a process liquid nozzle toward the principal face of the substrate being rotated.
