    摘要: Methods and systems of diagnosing an arcing problem in a semiconductor wafer processing chamber are described. The methods may include coupling a voltage probe to a process-gas distribution faceplate in the processing chamber, and activating an RF power source to generate a plasma between the faceplate and a substrate wafer. The methods may also include measuring the DC bias voltage of the faceplate as a function of time during the activation of the RF power source, where a spike in the measured voltage at the faceplate indicates an arcing event has occurred in the processing chamber. Methods and systems to reduce arcing in a semiconductor wafer processing chamber are also described.

    摘要: A filter for filtering a fluid in a substrate processing apparatus comprises first and second stages that are connected to one another. A delivery system provides a vaporized liquid to the filter. The first stage of the filter comprises a basic compound, and the second stage of the filter comprises a desiccant. A second filter comprises a permeation filter with permeable membrane to filter the fluid. Methods of filtering the fluid to reduce formation of undesirable process residues using the filter(s) are also described.
