Patent ID: 8133327

Claim:
A substrate processing method that processes substrates, wherein said method employs a common substrate processing apparatus having a function of supplying a substrate with a plurality of kinds of chemical liquids, said substrate processing method comprising: processing a substrate with a chemical liquid selected from the plurality of kinds of chemical liquids in the substrate processing apparatus; and drying a substrate, having been processed with the selected chemical liquid, wherein in a case where the processing of the substrate with the selected chemical liquid does not result in increasing of hydrophobicity of the substrate, the drying of the substrate is performed with a first gas being supplied into a processing space around the substrate thereby establishing an atmosphere in the processing space having a first humidity, while in a case where the processing of the substrate with the selected chemical liquid results in increasing of the hydrophobicity of the substrate, the drying of the substrate is performed with a second gas being supplied into the processing space around the substrate thereby establishing an atmosphere in the processing space having a second humidity, and wherein the second humidity is lower than the first humidity.
