ABSTRACT:
An ion sampling method for wafer provides a wafer in a sampling chamber, wherein the wafer surface that is going to be sampled faces upward; spraying an extraction liquid continuously on the wafer surface to form a liquid film thereon; keeping the thickness of the film constant for dissolving the ion contaminants in the extraction liquid; and collecting the extract solution at the bottom of the sampling chamber.
