Auto Centering System™ (ACS)
Speed achieving accurate wafer placement calibration, proper alignment and set-ups.
Product Video WaferSense® Auto Centring System (ACS)
Overview
Improve Yields
Improve yields and aids in predictive maintenance with accurate wafer handoff calibration.
- Capture offset (XY and Z) data quickly for center transfer positions as the wafer-like ACS moves through your semiconductor equipment.
- Improve the yield of your manufacturing process with properly calibrated equipment.
Repeatable & Reproducible
Achieve repeatable and reproducible semiconductor equipment setups.
Eliminate technician-to-technician variation with the ACS calibration which enables repeatable and reproducible setup and maintenance checks.
Reduces Equipment Downtime
From hours to minutes.
- Save time troubleshooting as the wireless and vacuum compatible ACS allows equipment to remain sealed during inspection.
- Increase equipment availability while reducing manpower and consumable expense.
Speed Trouble-shooting
Speed trouble-shooting and lower consumable expense with visual inspection.
- Receive real-time images as robots move the ACS through the tool. NordsonSpectrum™ software graphical user interface provides x, y and z offsets that eliminate guesswork.
- Inspect gap between focus ring and ESC chuck.
