Embodiments of an abatement apparatus are disclosed herein. In some embodiments, an abatement apparatus may include a scrubber configured to receive an effluent stream from a process chamber and further configured to remove first particles from the effluent stream; a scrubber conduit coupled to the scrubber to receive the effluent stream therefrom and configured to remove second particles from the effluent stream, the scrubber conduit having one or more inlets configured to provide a fluid to sufficiently wet an interior surface of the scrubber conduit to trap the second particles thereon and to wash the second particles therealong; and a central scrubber coupled to the scrubber via the scrubber conduit. In some embodiments, the scrubber conduit is downward sloping from the scrubber to the central scrubber. In some embodiments, a plurality of scrubbers may be coupled to the central scrubber via a plurality of scrubber conduits.

Methods and apparatus for controlling a processing system are provided herein. In some embodiments, a method of controlling a processing system may include operating a vacuum pump coupled to a process chamber at a first baseline pump idle speed selected to maintain the process chamber at a pressure equal to a first baseline pump idle pressure; monitoring the pressure in the process chamber while operating the vacuum pump at the first baseline pump idle speed; and determining whether the first baseline pump idle pressure can be maintained in the process chamber when the vacuum pump is operating at the first baseline pump idle speed.

A system for treating flammable effluent gas is provided. The system includes an exhaust conduit to carry the flammable effluent gas to an abatement unit, a control system coupled to the abatement unit to determine an operating parameter of the abatement unit, a bypass valve coupled to the exhaust conduit which is an operative responsive to the monitoring system, and a source of second gas to be mixed with the effluent gas diverted from the abatement unit when the bypass valve is operating in a bypass mode to provide a mixed gas having a flammability lower than the effluent gas. Methods of the invention as well as numerous other aspects are provided.

A method of developing an integrated abatement system is provided, including the steps: a) determining whether an integrated abatement system meets a destruction removal efficiency standard wherein the determination includes the steps: i) operating an electronic device manufacturing process tool using a best known method, whereby effluent containing a target species is produced; ii) abating the target species to form abated effluent, using an abatement system which is coupled to the process tool; and iii) calculating a destruction removal efficiency for the target species; and b) modifying the abatement system by altering at least one of a design parameter and an operating parameter of the abatement system to improve the destruction removal efficiency. Numerous other aspects are provided.

An effluent abatement system 200 that may be used to abate F2 gas content of effluent exhausted from a process chamber 35, such as effluent from a CVD chamber cleaning process includes a catalytic reactor 250 to reduce the content of F2 in the effluent 100. The system may further include a prescrubber 230 to add reactive gases to the effluent 100 and/or to treat the effluent 100 prior to treatment in the catalytic reactor 250. Alternatively reactive gases can be added to the effluent 100 by a gas source 220.
