摘要:
Methods and apparatus for treating effluents in process systems are provided In some embodiments, a system for treating effluent includes a process chamber having a processing volume; an exhaust conduit coupled to the process chamber to remove an effluent from the processing volume; and a reactive species generator coupled to the exhaust conduit to inject a reactive species into the exhaust conduit to treat the effluent, wherein the reactive species generator generates a reactive species comprising at least one of singlet hydrogen, hydrogen ions or hydrogen radicals. In some embodiments, a method for treating effluent includes flowing an effluent from a processing volume of a process system through an exhaust conduit fluidly coupled to the processing volume; treating the effluent in the exhaust conduit with a reactive species comprising at least one of singlet hydrogen, hydrogen ions, or hydrogen radicals; and flowing the treated effluent to an abatement system.

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.

A thermal abatement system is provided, including: a thermal abatement reactor; an inlet in fluid communication with the reactor; a process chamber in fluid communication with the inlet; a first sheathing fluid source in fluid communication with the inlet; a first flow control device, adapted to regulate a flow of a first sheathing fluid from the first sheathing fluid source; and a controller, in signal communication with the first flow control device, adapted to regulate the sheathing fluid by operating the first flow control device; wherein the inlet is adapted to receive an effluent stream from the process chamber and the first sheathing fluid from the first sheathing fluid source, to sheathe the effluent stream with the first sheathing fluid to form a sheathed effluent stream, and to introduce the sheathed effluent stream into the reactor.
摘要:
Methods and substrate processing systems are provided for controlling substrate heating efficiency and generating a desired temperature profile on the surface of a substrate when the substrate is disposed on a substrate support surface of a substrate support assembly. The substrate support assembly is provided with minimum software control and hardware requirement and includes a heating element comprised of multiple heating elements sections. The heating element is connected to a power source for adjusting the temperature outputs of the multiple heating element sections and providing adjustable multi-heating zones and desired temperature distribution over the substrate support surface of the substrate support assembly within a process chamber.
摘要:
A substrate processing system with independent substrate placement capability to two or more substrate support assemblies is provided. Two different sets of fixed-length lift pins are disposed on two or more substrate support lift pin assemblies of two or more process chambers, where the length of each lift pin in one process chamber is different from the length of each lift pin in another process chamber. The substrate processing system includes simplified mechanical substrate support lift pin mechanisms and minimum accessory parts cooperating with a substrate transfer mechanism (e.g., a transfer robot) for efficient and independent loading, unloading, and transfer of one or more substrates between two or more processing regions in a twin chamber or between two or more process chambers. A method for positioning one or more substrates to be loaded, unloaded, or processed independently or simultaneously in two or more processing regions or process chambers is provided.
