Double XYZ wafer positioner for scanners, microscopes and wafers up to 12 inch / 300 mm (clean room ISO2) | Stroke 720 x 720 x 100 mm
Inspection and Mikroscopy

Double XYZ wafer positioner for scanners, microscopes and wafers up to 12 inch / 300 mm (clean room ISO2) | Stroke 720 x 720 x 100 mm - Inspection and Mikroscopy


High throughput screening of wafers up to 12"

The inspection system with travel ranges up to 720 mm provides simultaneous high dynamic inspection of multiple 300 mm / 6" wafers. The completely ready-to-use motion system, consisting of the axes, the granite base with gantry, the cable management and the motion controller can be individually configured according to the customer's requirements.

Automated inspection in 3-shift operation

  • Ideal for automated inspection of wafers with:
    - 2x X-axes each for scanners / microscopes up to 25 kg
    - 2x Y-axes each for chucks / sample carriers up to 23 kg
  • Highly dynamic positioning up to max. 1000 mm/s with travel ranges up to 720 mm
  • Designed for use in 3-shift operation up to clean room class ISO 2
  • Low maintenance due to fast system replacement on the granite structure

Optionally expandable:

  • Version for clean room ISO 14644-1 (up to class 1 on request)
  • Connections for exhaust and revolving belt covers
  • Available also as single portal
  • Ready-to-use control system with pre-configured controller incl. sample software
  • Individual solution development with 3D design for the positioning task

Individual extensions and customizations

Engineering services include the fitting of the systems to your structure and the desired motion control or the completely individual solution development with 3D design for the application-specific positioning task.

Furthermore, we develop prototypes and like to adapt the systems to the environmental requirements of your application particle emission, radiation, temperature, precision special parts manufacturing, working height, collision protection, safety concept, compensation factor and filter, sensor mounting, brake, decoupling, special lubrication, special colors, holders, adapters, special motors with pharmaceutical approval, comprehensive documentation, test protocoll, llife cycle tests.
