Abstract:
A method for detecting a location of contaminant entry in a processing fluid production and distribution system, the method comprising the steps of:(a) placing a wafer in a clean container;(b) connecting the clean container to a test point within the processing fluid production and distribution system;(c) allowing processing fluid from the test point of the processing fluid production and distribution system to flow through the clean container;(d) drying the wafer, including the following substeps:(d.1) shutting off processing fluid flow through the clean container,(d.2) transporting the clean container to a clean environment without emptying processing fluid within the clean container,(d.3) in the clean environment emptying the processing fluid from the clean container, and(d.4) completely drying the wafer using an isopropyl alcohol dryer; and,(e) testing the wafer for existence of contaminants.
