    摘要: Embodiments disclosed herein include an abatement system for abating compounds produced in semiconductor processes. The abatement system includes an exhaust cooling apparatus located downstream of a plasma source. The exhaust cooling apparatus includes at least one cooling plate a device for introducing turbulence to the exhaust flowing within the exhaust cooling apparatus. The device may be a plurality of fins, a cylinder with a curved top portion, or a diffuser with angled blades. The turbulent flow of the exhaust within the exhaust cooling apparatus causes particles to drop out of the exhaust, minimizing particles forming in equipment downstream of the exhaust cooling apparatus.

    摘要: An apparatus and method for sequential application of cleaning fluids for improved maintenance of chemical mechanical polishing (CMP) systems is disclosed. A method includes transferring a first substrate to a first polishing station of a plurality of polishing stations, polishing the first substrate at the first polishing station, transferring the first substrate to a second polishing station, and transferring a second substrate to the first polishing station. The method includes cleaning a first surface of a plurality of surfaces of the polishing system by dispensing a first cleaning fluid from a first one or more nozzles of a plurality of nozzles to direct the first cleaning fluid onto the first surface and dispensing a second cleaning fluid from the first one or more nozzles to direct the second cleaning fluid onto the first surface, where the second cleaning fluid is different from the first cleaning fluid.
