Abstract:
A method of handling a semiconductor wafer comprising the steps of:providing a wafer carrier having a plurality of spaced support elements defining a wafer support plane and configured to receive spaced peripheral portions of a wafer, said carrier having a frame spaced below said plane connecting the support elements;inserting an end effector carrying a wafer between the plane and the frame to transfer a wafer to said carrier;inserting an arm of a wafer handler beneath said carrier;lifting said carrier without contacting the wafer;rotating said handler, with said carrier and wafer supported by said arm, to a second station;lowering said handler arm to transfer the carrier and wafer onto a plurality of spacers at said second station; androtating said wafer handler arm without said carrier and wafer to a position out from beneath the carrier.
