Zusammenfassung: | A system includes a plurality of spindle arms located above a plurality of stations in a processing chamber to transport a semiconductor substrate between the stations. The spindle arms reside in the processing chamber during processing of the semiconductor substrate. The system comprises first gas lines arranged below the stations to supply a purge gas. The system comprises second gas lines extending upwards from the first gas lines to supply the purge gas to the spindle arms during the processing of the semiconductor substrate in the processing chamber. |
