Abstract: An apparatus for extracting inorganic ionic contaminants from a front surface of a silicon wafer for chemical analysis. The apparatus includes a container adapted to receive the wafer and inhibit air circulation over the front surface of the wafer. The container has a support for holding the wafer in a generally level orientation with the front surface of the wafer facing upwardly, an inlet orifice for introducing a layer of extraction fluid to the front surface of the wafer, and a sampling device for taking a sample from the layer of extraction fluid on the front surface of the wafer.
