SUBSTRATE WASHING METHOD
Document Type and Number:
WIPO Patent Application WO/2010/104206
Kind Code:
A1
Abstract:
A substrate washing method which is able to be implemented by a simple apparatus configuration and washes a substrate, which has a fine pattern formed thereon, in a short period of time without having a detrimental effect on that fine pattern. The method comprises transporting the wafer (W) from a processing chamber, which processes the surface of the wafer (W) in a predetermined manner, to a washing chamber, which washes the wafer (W); cooling the wafer (W) inside the washing chamber to a predetermined temperature; feeding superfluid helium as a superfluid to the surface of the wafer (W); and washing away the contaminating components in the fine pattern by flushing out the superfluid from the surface of the wafer (W).
