While E-beam can be used for production where multiple substrates are coated simultaneously. Effusion cell is used for single substrate. In both cases, the target material is heated by either hot filament or an e-gun.

E-beam can go up to 3,000 degree Celsius . OUr beam is shaped and directed towards the target at exactly 90 incident angle. This is critical in the performance of an e-beam system.

When deposit metal onto substrate, DC power is used. When deposit dielectric material, F power and matching network is used.
