The EVG NIL is a system for imprinting in polymers (Hot embossing), and for bonding on wafer scale. 3 different types of [[Specific Process Knowledge/Bonding|bonding]] can be done: Anodic, Eutectic and Fusion. Furthermore it is possible to align the wafers one wishes to bond. In principle it is also possible to align the substrate and stamp before imprint, but it is much more difficult.


It is possible to fill bonded cavities with a desired gas. At the moment we have SF<sub>6</sub> on the system, but if you would like another one, please contact Rune Christiansen.

Wafer Bonder 02: Positioned in cleanroom E-4

The Wafer bonder 02 is a system for bonding. 3 different types of bonding can be done: Anodic, Eutectic and Fusion. Furthermore it is possible to align the wafers one wishes to bond. It is also possible to process and align pieces.

The user manual, quality control procedure and results, user APV(s), and contact information can be found in LabManager: Equipment info in LabManager
