Abstract:
1. A semiconductor wafer transport method for transporting a semiconductor wafer having a first surface and a second surface opposite said first surface, said method comprising: a supporting step for placing said semiconductor wafer with said second surface contacting a holding device, and supporting, with said holding device, said semiconductor wafer in a planar state with a warp thereof corrected by a pressing device having a plate defining a flat pressing surface for pressing said semiconductor wafer, and said pressing device pressing said semiconductor wafer, with said plate and said first surface of said semiconductor wafer in surface-to-surface contact with each other, the flat pressing surface entirely covering said first surface of said semiconductor wafer; and a transporting step for transporting to each processing stage said semiconductor wafer supported in the planar state with the warp corrected in said supporting step.
