The AJA ATC-ORION 8000 E-beam evaporator is a performance UHV thin film deposition system. The system contains four material pockets for deposition of single and multi-layer films without breaking vacuum. The substrate holder can handle substrates up to 4 inches in diameter and allow simultaneous rotation. It also can be heated up to 850 °C in suitable environment. A load-lock chamber allows quick removal and insertion of samples without venting the chamber. The quartz crystal thickness monitor ensures the precise control of the deposited film thickness.
