  • Method for detecting a location of contaminant entry in a processing fluid production and distribution system
    Patent number: 6037182
    Abstract: A method is used to detect a location of contaminant entry in a processing fluid production and distribution system. A wafer is placed in a clean container. The clean container is connected to a test point within the processing fluid production and distribution system. Processing fluid from the test point of the processing fluid production and distribution system is allowed to flow through the clean container. The wafer is dried. The wafer is then tested for the existence of contaminants.
