Wafer Bonding System

Versatile manual wafer bonding system for academia and industrial research

The EVG501 is a highly flexible wafer bonding system that can handle substrate sizes from single chips to 150 mm (200 mm in case of a 200 mm bond chamber). This tool supports all common wafer bonding processes such as anodic, glass frit, solder, eutectic, transient liquid phase, and direct. The easy access bond chamber and tooling design allows for quick and easy retooling for different wafer sizes and processes with a conversion time of less than 5 minutes. This versatility is ideal for universities, R&D facilities, or low-volume production. The basic design of the bond chambers is the same on the EVG HVM tools, such as the GEMINI, and the bonding recipes are easily transferable; this allows for easy scale up of production volumes.


  • Bond chambers with 150 mm or 200 mm heaters
  • Unique pressure and temperature uniformity
  • Compatible with EVG mechanical and optical aligners
  • Flexible design and configurations for research
    • From single chips to wafers
    • Various processes (eutectic, solder, TLP, direct bonding)
    • Optional turbopump (<1E-5mbar)
    • Upgradeable for anodic bonding
    • Open chamber design for easy conversion and maintenance
  • Pilot production compatible
    • Optimum cost of ownership in its class
    • Open chamber design for easy conversion and maintenance
    • Smallest footprint for a 200 mm bonding system: 0.8 m2
    • Recipes are fully compatible with EVG HVM bonding systems
