Abstract:
Methods and apparatus for recovery and reuse of reagents are provided herein. In some embodiments, a system for processing substrates may include a process chamber for processing a substrate; a reagent source coupled to the process chamber to provide a reagent to the process chamber; and a reagent recovery system to collect, and at least one of purify or concentrate the reagent recovered from an effluent exhausted from the process chamber. In some embodiments, a method for recovering unreacted reagent may include providing reagent from a reagent source to a process chamber; exposing a substrate disposed in the process chamber to the reagent, forming an effluent; exhausting the effluent from the process chamber; and recovering unreacted reagent from the effluent in a reagent recovery system.
Abstract:
A method for operating an electronic device manufacturing system is provided, including: introducing an inert gas into a process tool vacuum pump at a first flow rate while the process tool is operating in a process mode; and introducing the inert gas into the process tool vacuum pump at a second flow rate while the process tool is operating in a clean mode. Numerous other embodiments are provided.
Abstract:
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.
Abstract:
A method for operating one or more electronic device manufacturing systems is provided, including the steps 1) performing a series of electronic device manufacturing process steps with a process tool, wherein the process tool produces effluent as a byproduct of performing the series of process steps; 2) abating the effluent with an abatement tool; 3) supplying an abatement resource to the abatement tool from a first abatement resource supply; 4) changing an abatement resource supply from the first abatement resource supply to a second abatement resource supply, wherein changing the abatement resource supply comprises: i) interrupting a flow of the abatement resource from the first abatement resource supply; and ii) beginning a flow of the abatement resource from the second abatement resource supply; and 5) continuing to perform the series of process steps with the process tool, while changing, and after changing, the abatement resource supply.

Abstract:
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.
Abstract:
Exhaust condensate removal apparatuses for abatement systems and methods of removing exhaust condensate from abatement systems are described. An exhaust condensate removal apparatus includes a cabinet exhaust and a process gas exhaust, the process exhaust openly cross-exchanged with the cabinet exhaust. Another exhaust condensate removal apparatus includes a cabinet exhaust and a process gas exhaust, the process exhaust closedly cross-exchanged with the cabinet exhaust.
