Abstract

The wafer transport apparatus prevents contaminant deposited on an unprocessed wafer from adhering to a processed wafer. Carrying-in load portA is loaded with a FOUPstoring an unprocessed wafer W. Carrying-in chamberA has a transport robotA which takes out the unprocessed wafer Wfrom the FOUP. Carrying-in load lockA is accessed by the transport robotA from the carrying-in chamberA side. Carrying-out load portB is loaded with the FOUPthat can store a processed wafer W. Carrying-out chamberB has a transport robotB which passes the processed wafer Wto the FOUP. Carrying-out load lockB is accessed by the transport robotB from the carrying-out chamberB side. The carrying-in chamberA and carrying-out chamberB are separated from each other. The carrying-in load lockA and carrying-out load lockB are arranged on different stages.
