The pre-aligners provide alignment for 150 mm (6") up to 300 mm (12") wafers. They center the wafer, find the precise orientation of its notch or flat and align it exactly.
Due to “vacuum handshake” between end-effector and pre-aligner the wafer is always secure with a minimal touch at the wafer back side. Several mechatronic end-effectors can be used for loading and unloading of a pre-aligner.
