Key Takeaways:
Semiconductor manufacturing needs nanometer-level motion stability. Hydrostatic rotary tables provide non-contact, vibration-isolated rotation for wafer dicing, grinding, and precision lithography stages.
Nanometer Stability for Wafers
In semiconductor manufacturing, even sub-micron vibration during wafer dicing or backside grinding can ruin yield. A hydrostatic rotary table isolates the rotating element on a pressurized oil film, removing contact friction and the micro-vibrations that mechanical bearings transmit.

Why Hydrostatic for Lithography and Dicing
The Marusaku rotary table reaches rotary positioning accuracy of ±0.001 mm with an oil film that delivers high stiffness (far above rolling bearings) and excellent damping. For wafer dicing and grinding, this means flat, chatter-free cuts and consistent die quality.
Clean and Stable Motion
Because the film is non-contact, there is no wear debris and no thermal growth from friction. The result is repeatable, nanometer-class motion stability suited to cleanroom-adjacent precision processes.
