Zusammenfassung:The harmful effects of accumulating droplets of process liquid on the outer surface of a dispense nozzle are prevented by equipping an apparatus for process wafer-shaped articles with a blow-off block that blows the droplets off the nozzle outer surface before they can coalesce and drop in an uncontrolled manner onto the work piece. The nozzle preferably has a polished and tapered outer surface to aid in blowing off any accumulated droplets of process liquid from the outer surface.
