Design Features
- HV magnetron sputter deposition system with combination of confocal and face to face sputter up configurations.
- Up to four 2″ magnetrons in confocal configuration.
- Two 2″ magnetrons with manual in situ tilting.
- Two 2″ magnetrons with fixed angle face to face setup.
- All magnetrons with easy changeable magnetic system for use with ferromagentic or non-ferromagnetic target materials.
