Title:
METHOD FOR DRYING SUBSTRATE
Document Type and Number:
Japanese Patent JP2004228203
Kind Code:
A
Abstract:

To provide a method for drying a substrate that can prevent the occurrence of a water mark and has satisfactory throughput even in the substrate having a surface, where the strength of hydrophilic properties is different.

In a substrate treating method for removing a liquid DIW adhering onto the surface of a substrate W, the surface of the substrate W has portions 10, 11 where the strength of hydrophilic properties is different each other. Rotating the substrate W removes the liquid DIW from the portion 10 whose hydrophilic properties are weak. Increasing a rotational speed for rotating the substrate W removes the liquid DIW from the portion 11 whose hydrophilic properties are strong.
