High-precision positioning of wafers in inspection systems


The current standard wafer has a diameter of 8“. The industry is moving towards manufacturing larger wafers.  Technologies for production processes such as stealth dicing, lithography, doping, implanting, planarization makes precise positioning of the bigger substrates a must. Thin film technology places great demands on the substrates and their structures.

The piezosystem jena GmbH now offers a positioning system for the inspection of the new larger wafers (PZ250 CAP WL). This system is designed to position wafers with a diameter up to 12” using precise hold and repeat positioning with the same precise precision. The system can be used as an automated inline controller or as a stand-alone positioner. The highly precise positioning system allows steady processes in production and process control. The new system will also shorten cycle times in quality control. Piezosystem jena’s new system offers positioning in microseconds with steps of a few microns with repeatability in nanometers. Your crucial data will be obtained quickly with excellent performance and value.

Applications:

  • semi conductor and solar producing
  • lithography
  • display production
  • surface structuring
  • Surface inspection
  • measurement chips
  • measurement of conductor tracks
  • measurement systems
  • quality control
  • bonding-technology

 

Requirements:

  •  measuring range < 300 µm
  • small, repeatable steps
  • movement free of displacement
  • short rise time
  • controlled positioning
