The HybrYX® single plane XY hybrid stages offers the advantages of a single plane air bearing stage at a much lower cost than previously possible. HybrYX is well suited for semiconductor wafer inspection systems as well as being an excellent choice for use in large substrate (flat panel display and photovoltaic panel) inspection and processing tools.
HybrYX® stages blend the cost-effectiveness of mechanical bearings with the precision of a single plane air bearing carriage to deliver a powerful combination of throughput, precision and value. During motion, a ceramic carriage freely slides in X and Y on a precision lapped granite reference plane using a proprietary pressure-vacuum air bearing design. This XY carriage is pressure-vacuum preloaded to, and guided along the Y-axis by a rigid and lightweight ceramic beam. The beam is supported (and guided) at each end by recirculating ball bearing carriages resulting in a low-profile design that is extremely rigid, well-damped, and capable of quick & precise point-to-point moves and exceptional high-speed scanning performance. For large payloads, such as Generation-5 LCD display or Photovoltaic panels, the HybrYX-G5 offers an oversized carriage with higher air bearing load capacity on both the horizontal and vertical reference surfaces.
HybrYX® was developed to overcome the disadvantages found in conventional stacked XY stage systems. Truck-and-rail based stages have limited performance capabilities, long-travel crossed roller bearing designs are hindered by large footprints and may not have adequate life-time or MTBF characteristics, and a (pure) dual axis air bearing is often cost prohibitive.
