A filter is operably disposed to filter the wash fluid recirculated by the main pump. A backflush line has an outlet disposed downstream of the filter, and a backflush pump is configured to supply backflush fluid through the backflush line against the filter. A reservoir separate from the sump is provided and sized to hold a measured amount of fluid. The backflush pump draws the backflush fluid from the reservoir at a defined time.

  • Publication number: 20150047674
    Abstract: Techniques disclosed herein include a method and apparatus for stripping resist from a substrate without using high concentrations of toxic chemicals and without needing frequent bath replacement. Techniques include using a chemistry that lifts-off the resist, without substantially dissolving the resist, coupled with mechanically breaking removed resist into small particles using mechanical agitation and high fluid flow. Resist particles can then be removed from the vicinity of the wafer by a high-flow circulation out of a processing tank. Circulating flow can then be filtered to remove the resist particles from the circulating fluid and reintroduced into the processing tank. A filtering system can also remove particles from filters either during circulation or with circulation stopped.

  • Patent number: 8950690
    Abstract: An anti entrapment fail safe drain having a drain cover for partially covering an influent opening; a pressurized supply line; and a nozzle assembly in communication with the pressurized supply line and mounted within a drain sump. The nozzle assembly is for directing a pressurized liquid in a pattern over a surface of the drain cover when the drain cover and the nozzle are immersed in the liquid such that a portion of the liquid above the pattern or objects suspended in standing liquid can not be pulled directly toward the drain cover through a drain inlet opening. The drain also has an effluent opening for connecting to the drain sump arranged such that the liquid flows into a pipe in a first direction. The pressurized supply line is arranged inside the pipe for returning the liquid to the nozzle assembly in a second direction opposite the first direction.
