ABSTRACT:
A non-vacuum semiconductor pick-up and transfer apparatus for handling semiconductor wafers. A flat tapered blade, with front and rear arcuate abutment surfaces adapted to hold a wafer, is provided. In use the blade is thrust between spaced wafers supported in a holder, lifted to retain the wafer between the abutment surfaces, and removed from the holder. The thin and tapered blade shape minimizes damage to the associated wafers in the event of a misalignment of the blade with the wafers.
