EB Source for Metal Film

EGL Series



EGL-80M electron beam evaporation source is designed to improve performance and reliability based on ULVAC's many years of technical experience and achievements.
This evaporation source has a four-point switching hearth with a maximum input power of 16kW.
The crucible has a large capacity of 110 cc per piece , which enables the high-speed deposition of thick films.


  • Large-capacity multi-layer deposition is possible by adopting a large capacity 110cc 4-point switching hearth.
  • The electron beam is deflected by the electromagnetic field, the effect of secondary electrons on the deposition target is extremely small.
  • By scanning the beam spot on the X-axis and Y-axis even with a purifying substance, it is possible to eliminate the pitting phenomenon and evaporate smoothly. (Japan patern 831485, 843447)
  • The electron beam is deflected 270°, so it is not exposed to the above from the vaporized material and the filament has a long life.
  • Since the emitter assembly can be easily attached and detached, it is easy to replace the filament, insulator, etc.
  • Adopting a water-cooled magnet coil allows continuous operation in high temperature atmosphere.
  • The hearth position detection mechanism is installed as an option and hearth rotation can be automated.
