Precision Motion Control Systems for Semiconductor Manufacturing

High-yield chip fabrication relies on specialized motion control systems for semiconductor manufacturing. We engineer our gear reducers and gearboxes to deliver smooth, highly accurate positioning. Semiconductor environments frequently require cleanroom operation alongside minimal particle generation. Our high precision gearbox systems provide the exact torque needed to move delicate wafer stages without inducing harmful vibrations.This focused mechanical control directly reduces positioning errors and increases throughput for high-speed automated environments.

Semiconductor wafers are produced in a vacuum. While motion components are most often located outside the vacuum chamber, we have experience engineering gearboxes to operate directly inside a vacuum. We accommodate these strict conditions by carefully specifying all materials throughout the unit, including the required grease.

Equipment and Systems Utilizing Our Zero-Backlash Gearboxes

We supply strain wave gearboxes for a variety of critical semiconductor manufacturing systems, including wafer handling robotics. Our engineering focuses on integrating seamlessly into machinery that demands exact positioning and continuous reliability.

GAM precision gearboxes support the four building block processes of semiconductor fabrication:

Deposition (PVD, CVD, ALD)
Patterning (lithography)
Dry and plasma etching
Electrical doping modification

For example, we supplied a modified EPL planetary gearbox to control the shutter in a plasma vapor deposition (PVD) process. Planetary gearboxes are inherently balanced, providing smooth motion with zero vibration. In this specific case, we customized the EPL gearbox to meet a strict requirement of less than 1 arcmin of backlash.

Systems utilizing our motion control technology include:

Testing equipment for quality assurance processes
Vision inspection systems requiring steady camera movement
Metrology systems for precise measurement operations
Lithography systems needing extreme micro-positioning accuracy
Pick and place gantry systems for rapid wafer transfer

Engineering Advantages for Semiconductor OEMs

Semiconductor OEMs face unique design constraints when developing compact and efficient machines. We partner directly with engineering teams to provide customized mechanical motion control solutions that fit specific spatial requirements. Our gearboxes and gear reducers are engineered to eliminate redundant components, which reduces the overall footprint of your equipment and streamlines assembly.

GAM gearboxes provide the performance that chip manufacturing requires:

Extremely high positioning accuracy with very low backlash of less than 1 arcmin
High torsional stiffness with low lost motion
High efficiency
Smooth motion with no vibration

For some applications with strict power draw limitations, integrating our gearboxes allows you to reduce the size of the motor to help meet those power specifications.

Key advantages of integrating our Gearboxes include:

Zero-backlash configurations for exact wafer positioning
Space-saving miniature designs to maximize machine real estate
Custom modifications to meet strict environmental requirements
High torque capacity within highly concentrated housings
