Pursuing the ultimate precision in linear guide stages!
In addition to repeatability better than 1μm,
dynamic motion control has been enhanced,
which is ideal for speed stability
and multi-axis synchronized accuracies!
As semiconductor manufacturing processes become increasingly miniaturized, the demands for securing yield rates and achieving high throughput are becoming ever more stringent.
To contribute to the increasingly complex semiconductor manufacturing process, YASDA has maximized the performance of its linear guides by thoroughly pursuing not only compensational technology but also mechanical precision.
At SEMICON JAPAN 2025, we will exhibit a stage suitable for 600mm panel sizes. Featuring XYZ axes with repeatability in the 0.1μm range, it is also equipped with our proprietary θ axis. This stage accommodates diverse applications within semiconductor manufacturing.
Three core technologies of YASDA
for achieving precision stages,
using designs and skills sophisticated longer than a half century

Pursuing precision in every process
Manufacturing
Technology
Mastering Straightness, Parallelism, and Perpendicularity, YASDA ensures uncompromised sub-micron assembly. With over 50 years of excellence, we provide a complete one-stop manufacturing service—from parts processing to inspection—under thorough quality control.

Accurate positioning and speed
High tracking control
Beyond repeatability, YASDA achieves high dynamic performance—including constant speed and multi-axis synchronization—via thorough servo tuning. Additionally, our units feature superior thermal rigidity and vibration resistance, enabling high-value manufacturing.

As flat and straight as possible
Hand scraping
that makes beyond
machining accuracies
Craftsmen use “hand scraping” and high-precision autocollimators to install linear guides with straightness exceeding machining limits. This precise alignment minimizes individual errors, ensuring consistent accuracy across all units.
Expanding the precision of high-rigidity linear guide stages
to the level of air slide stages
YASDA offers linear guide stages that combine precision and rigidity.
In the rapidly advancing semiconductor field of 2.5D/3D packaging, high alignment accuracy is required in the process of bonding chips together. In this context, YASDA meets these requirements by manufacturing stages that combine “sub-micron accuracy” and “rigidity” in the development of equipment for advanced processes. Linear guide ways avoid the pulsation that occurs with static pressure guide ways, and YASDA's outstanding assembly technology achieves low waving, high repeatability, and stable positioning. YASDA’s linear guide stages are suitable for equipment which are excellent for bonding and inspection processes where air slides are not perfectly suited for handling heavy loads. These need to be stable under conditions like high loads and high temperature.

Large XYZθ Stage for Semiconductor Manufacturing and Inspection Equipment
【Exhibited at SEMICON JAPAN 2025】
Even with large strokes, it achieves both high repeatability and
stable attitude stability
A stage equipped with two XY axes, a Z axis, and a θ axis for alignment, designed for manufacturing equipment used in panel-level packaging processes.
In addition to high positioning accuracy throughout the entire stroke range, the mechanical stage minimizes displacement during operation, contributing to enhanced production efficiency in advanced semiconductor manufacturing.
Customization is possible to meet your specifications and requirements, for example with high load capacity specifications or extended stroke.
※ This stage is a prototype.
