ALIO Industries: Leading-Edge 6-D Nano Positioning® Air Bearing Systems for manufacturing, inspection/repair, and metrology applications.
ALIO Industries has developed patented designs for Planar and Nano Z® air bearing motion systems, well-positioned for TRUE NANO® precision demands in photovoltaic, semiconductor, ink jet deposition, lithography, and optical inspection applications. Contact us to learn more about our advanced air bearing systems.
ALIO’s patented 2-axis planar XY air bearing system has set the bar in the world of 6-D Nano Positioning®. As both axes use the same highly precise granite base as reference, advanced flatness of just a single micron over several hundreds of mm (or even meters) of travel ranges can be achieved.
Thanks to ALIO’s patented design and the proprietary 6-D Nano Precision test methods, this highly stiff family of planar xy air bearing motion systems delivers sub-micron accuracy, and a +/- 100nm bi-directional repeatability even in higher quantities for serial machine production. With 200 mm to 800mm standard versions, and possible customizations to over 3 meters of X and Y travel, this product family has no equal for True Nano® precision in any kind of measurement / metrology applications and in the semiconductor industry.
Powerful linear direct drives and air bearings make these motion systems perfectly suited to high precision, high throughput applications that require smooth continuous scanning or a fast step-and-settle process over very long distances.
For more information on the planar xy air bearing stages, and the numerous customization options available, contact ALIO or have a brief look at following data sheet:
For many high-precision applications such as photonics, precision scanning in semiconductor or flat panel display manufacturing, or metrology, Linear Air Bearing stages (that float on a thin film of air) are a perfect solution.
Because the motion Is frictionless, no particles are formed, and the planar guideways they float upon are much more precise than mechanical bearings.
ALIO’s linear X Air Bearing stages are characterized by being very smooth and accurate, and provide extremely straight and flat motion. Out extremely high motion fidelity Motion Systems are based on a planar air bearing design driven by linear motors. Our Air bearing stages are used where ultra-precision is needed such in applications like wafer inspection, scribing, and flat panel inspection.

ALIO’s family of linear motor driven, vertical Z-lift stages with Air Bearing counterbalance are characterized by their low profile and extremely long travel ranges. Using high precision crossed roller bearings and linear encoders, the stages are equipped with a frictionless air bearing pneumatic cylinder. Similar to the GeoSymmetric series of stages, these long travel Z stages have counterbalance, motor, bearings, and encoder all placed on an approximate centerline of the stage. Payloads may be mounted directly to the face of the stage.
The Z-ABCB series — with its frictionless air bearing pneumatic cylinder counterbalance — can carry payloads of up to 25kg over 200mm or more.
Details:
NANO Z® patented Z-lift air bearing stages overcome the legacy design issues associated with z-wedges and other vertical stages. They use a novel combination of air-bearings plus two voice coil motors in a compact footprint with up to 50mm travel.
Using air bearings means negligible friction which enables unparalleled accuracy and repeatability down to low double-digit nanometers. Variable counterbalancing easily handles heavy weights like wafer chucks, while still achieving nano-level precision over the full travel range.
The Nano Z® design places vertical force in line with the payload, and this makes it possible to place the stage directly below the payload instead of beside it, avoiding inevitable cantilever inaccuracies and nearly eliminating pitch, yaw and roll.
Dimensions and specification can be found in following data sheet:
When the highest rotational precision is required, manufacturers can choose from ALIO’s line of air bearing rotary stages. Air bearings allow the stage to move without mechanical contact and therefore movement is frictionless and without wear. Errors like wobble, eccentricity, or runout can be minimized to get close to a perfect, smooth 360 degree movement even at high speeds or when the rotational stage is mounted vertically. Thanks to powerful torque motors, both constant continuous rotation as well as step-and-settle processes can be performed in an equally precise and reliable way.
It is no surprise that ALIO’s rotational air bearing stages can therefore be found in the most precise applications within the semiconductor, metrology, and photonics industries.
