    Abstract: The present disclosure relates to methods and apparatus for treating vacuum processing system exhaust gases. In addition, methods and apparatus for maintenance of foreline plasma reactor subsystems are disclosed. In some embodiments, an apparatus for treating an exhaust gas in a foreline of a vacuum processing system includes a plasma source coupled with a foreline of a process chamber, a treatment agent source coupled with the plasma source, and a downstream trap to cool an exhaust stream and trap particles in the exhaust stream. In some embodiments, multiple foreline plasma reactor subsystems are used with a vacuum processing system, and one foreline plasma reactor subsystem can be isolated and maintained (e.g., cleaned) while exhaust gas treatment continues in another foreline plasma reactor subsystem and processing continues in the vacuum processing system.

    Abstract: Implementations of the present disclosure relate to systems and techniques for abating F-gases present in the effluent of semiconductor manufacturing processes. In one implementation, a water and oxygen delivery system for a plasma abatement system is provided. The water and oxygen delivery system comprises a housing that includes a floor and a plurality of sidewalls that define an enclosed region. The water and oxygen delivery system further comprises a cylindrical water tank positioned on the floor, wherein a longitudinal axis of the cylindrical water tank is parallel to a plane defined by the floor and a length of the water tank is 1.5 times or greater than the diameter of the cylindrical water tank. The water and oxygen delivery system further comprises a flow control system positioned within the housing above the cylindrical water tank.

    Abstract: Embodiments disclosed herein include a plasma source for abating compounds produced in semiconductor processes. The plasma source has a first plate and a second plate parallel to the first plate. An electrode is disposed between the first and second plates and an outer wall is disposed between the first and second plates surrounding the cylindrical electrode. The plasma source has a first plurality of magnets disposed on the first plate and a second plurality of magnets disposed on the second plate. The magnetic field created by the first and second plurality of magnets is substantially perpendicular to the electric field created between the electrode and the outer wall. In this configuration, a dense plasma is created.
