Measuring Thin High Bow Wafers
FRT Metrology Tool with integrated Bernoulli and vacuum chuck (developed by FRT) can handle extremely thin high bow wafers for measurement purposes, where the wafer needs to be flattened.
To effectively handle different sizes and types of wafers, different kinds of end effectors are required. To facilitate this, a specially designed dual end effector changing station with eight slots is integrated in the tool.
