Features
- Any multi-layer film deposition is possible by adopting a 4-point switchable hearth with a crucible capacity of 2.9 cc.
- The electron beam is deflected 225°, so it is not exposed to the vapor from the vaporized material and the filament has a long life.
- Since the electron beam is deflected by the electromagnetic field, the influence of secondary electrons on the deposition target is extremely small.
- By scanning the beam spot in the X-axis and Y-axis directions even with a sublimable substance, the partial digging phenomenon can be eliminated and the entire crucible can be evaporated smoothly.
- Since the emitter assembly can be easily attached and detached, it is easy to replace consumable parts such as filaments and insulators.
