In a method and apparatus for processing wafer-shaped articles, a spin chuck is positioned inside a process chamber. The spin chuck is configured to hold a wafer-shaped article at a predetermined process position. A cover covers the spin chuck and is affixed to or integral with the spin chuck for rotation therewith. The cover has a central opening. A stationary nozzle assembly extends into the process chamber such that a discharge end of the stationary nozzle assembly passes through the central opening of the cover. The nozzle assembly comprises a rinse nozzle configured to direct rinse liquid radially outwardly of the nozzle assembly onto a downwardly-facing surface of the cover.
