  • Systems and methods for detecting contaminants
    Publication number: 20050183490
    Abstract: The present invention relates to a system and method for sampling a gas flow to measure one or more contaminants within a semiconductor processing tool. The system includes a portable unit containing one or more dry traps, Tenax traps and, if desired, wet impingers. The unit is coupled to a gas flow in a clean room and the dry traps. Tenax traps and wet impingers measure contaminants contained in the gas supply for a determined sampling interval. When the sampling interval is done, the unit is sent to an analysis facility for processing.
    Type: Application
