Nano Z® – Dual Voice Coil Stage with Air Bearings When Nanometer-Level Vertical Precision Is the Priority Some applications place ultimate Z-axis precision above almost every other consideration. ALIO's patented NANO Z® architecture combines air bearings with dual voice-coil motors to provide frictionless vertical motion in a compact platform. By aligning vertical force with the payload, the architecture reduces the cantilever effects that can translate into pitch, yaw and roll errors at the work point. The system offers up to 50 mm of travel, while variable counterbalancing enables demanding payloads such as wafer chucks to be managed without surrendering nano-level positioning performance. Air-bearing operation also eliminates mechanical contact and associated friction, supporting extremely smooth motion and repeatability into the low double-digit nanometer range. For semiconductor processing, advanced metrology and other applications where vertical motion can directly influence measurement or process integrity, NANO Z® provides precision by architecture rather than compensation.
