Abstract
A method and apparatus capable of eliminating occurrence of a development failure when a DI water discharge nozzleis scanned to dry a substrate by spinning. A substrate is held in a horizontal posture by a spin chuck and rotated about a vertical axis by a rotation motor, and when an outlet of the nozzle is scanned from a position opposed to a center of the substrate W to a position opposed to a circumferential edge while a cleaning solution being discharged, immediately after the nozzle has started to move, only one dried core is produced in the vicinity of the center of the substrate, and thus production of not less than two dried cores in the vicinity of the center of the substrate is prevented. The dried region is spread all over the surface of the substrate.
