Beschreibung
Zusammenfassung:	An apparatus for processing wafer-shaped articles comprises a rotary chuck adapted to hold a wafer shaped article of a predetermined diameter in a predetermined orientation. The chuck includes a heater comprising a plurality of gas nozzles directed toward a surface of a wafer shaped article when held by the chuck. The heater comprises a gas inlet and at least one heating element for heating gas to be discharged through the plurality of gas nozzles. The heater is configured to heat a wafer shaped article principally by convective heat transfer from heated gas discharged through the plurality of gas nozzles.
