Abstract:
A substrate treating apparatus of a multi-nozzle type, comprising:an outer tube nozzle having at a distal end thereof a wafer top for the to-be-treated substrate, the wafer top extending parallel to the to-be-treated substrate from the distal end and being adapted so as not to be in contact with the to-be-treated substrate during treatment; an inner tube nozzle being provided in the outer tube nozzle to form a multi-nozzle structure; a supporting stage which supports the to-be-treated substrate and is located below the multi-nozzle structure; a moving apparatus configured to move the supporting stage up and down to create a space between the to-be-treated substrate and the wafer top of the outer tube nozzle; and a supply device including at least one chemical fluid supply and a pure water supply, the supply device being configured to supply chemical fluids to the inner and outer nozzles so as to discharge the chemical fluids from the multi-nozzle structure to fill up the space created by the moving apparatus with a solution containing the chemical fluids, and supply pure water to the inner and outer nozzles so as to discharge the pure water from the multi-nozzle structure to fill up the space created by the moving apparatus with a solution containing the pure water.
