Customised 5-Axis Manipulator for cleanroom class 6 operation

Positioning stability, dynamics and precision are crucial in the field of in-line wafer inspection to

maximise throughput. PM was requested to deliver a multi-axis positioning solution for smooth

high-speed scanning and reliable operation.Our system engineers worked closely together with

the customer to understand their project needs and achieve critical project goals.

The application

For next-generation wafer inspection, the customer developed a

non-contact, non-destructive measurement for inline front-end

processes. The benefits range from stand-alone applications to

fully automated inline measurements where every single wafer

can be measured in production.

Results

• The first prototype was delivered within the time budget after

     the start of the project. This was a result of the fact that all

     company competences were combined. This allowed for

     great collaboration of the design, manufacturing and

     assembly processes;

• The box frame was optimised for stiffness to get a high as

     possible system bandwidth to make sure that settling times

     and accuracies were according to specification;

• The modular design allows for various configurations of the

     system. The system can either be equipped with 5 or 7

     motion axis. Also, if desired, a vibration isolation system

     can be integrated.
