Lift-off Wet Bench
This bench is only for wafers with metal!
The user manual, and contact information can be found in LabManager
Process information
Here are the main rules for lift-off bench use:
- Place the wafers in a dedicated wafer holder.
- Put the holder in the acetone and start the ultrasound. The strip off time is depending of resist thickness.
- Rinse your wafers for 4-5 min. in running water after stripping.
