6) Advanced design concept for a better performance to enhance production efficiency and qualified rate.
7) Ion source device for plasma cleaning and surface activity treatment to improve adhesion.
8) High-vacuum pumping time cut by 25% to 75% by Polycold – water vapor cryopump.

Polycold also named as Water Vapor Cryopump, effectively captures water vapor which comprises 65% to 95% of the residual gas in Hi-vac systems. Water vapor is typically the most reactive contamination present With Polycold, you can expect to increase product throughput in your existing system 20% to 100% and improve quality of deposition.

1. High-vacuum pumping time cut by 25% to 75%
2. Increased product throughput of 20% to 100%;
3. Typical payback times of less than one year;
4. Lower water vapor partial pressure during processing for higher film quality, better adhesion and more reproducible deposition.
