Product Specifications

Technical details and manufacturing context for Precision Stage

Definition
The precision stage is a critical component of wafer prober systems that provides nanometer-level positioning accuracy for semiconductor wafers during electrical testing. It enables precise alignment of wafer pads with probe needles, facilitates step-and-repeat testing patterns across the wafer surface, and ensures consistent contact force during probing operations.
Working Principle
The precision stage operates using high-resolution linear motors or piezoelectric actuators combined with laser interferometers or optical encoders for position feedback. It receives coordinate commands from the prober's control system and moves the wafer in X, Y, and sometimes Z axes with sub-micron accuracy, compensating for thermal expansion, vibration, and mechanical drift.
