Abstract:
A method for drying wafer-shaped articles comprises rotating a wafer-shaped article of a predetermined diameter on a rotary chuck, and dispensing a drying liquid onto one side of the wafer-shaped article. The drying liquid comprises greater than 50 mass % of an organic solvent. During at least part of the dispensing step, the wafer-shaped article is heated with a heating assembly. During at least part of the dispensing step a fluorine-containing compound is present in the drying liquid or in a gas that surrounds the drying liquid as the drying liquid contacts the wafer-shaped article.
