The method of electron beam evaporation is described as with deposition rates from 100 to some 1000 μm min-1. It is discussed the effects taking place at the high rates as well as the impact on the ongoing regime. There are major uses for a high rate e-beam evaporation. These are the coating of paper and plastic films with aluminium or magnetic layers. It will be given a specific attention to the thermal substrate load and its costs during the operating mode. Electron Beam is called a stream of electrons or physics a beam. It produced by a single source that travel at the same speed and in the same course. While evaporation is a process which a liquid becomes gas. Usually occur when a liquid exposed to heat.
The e-beam and evaporation can be used in the same manner. So what exactly is e-beam evaporation? E-beam (Electron Beam) evaporation is a process alike to thermal evaporation. The example of it is the source material when heated, the above its boiling temperature and evaporated that forms a film on the surfaces. It will be stroke by the evaporated atoms. It allows the operator to evaporate materials that are challenging during process by the use of standard resistive thermal evaporation. The e-beam evaporation makes the impossible possible. It includes high-temperature materials such as titanium and gold, and ceramics like alumina and silicon dioxide.
So here is the best e-beam evaporation techniques. The electron beam evaporation process will start with the foundation material placed in the crucible a filament under the crucible is heated. By applying a huge voltage, the electrons are drained from the filament and concentrated as a beam on the source material by some bending magnets. The beam will have swept across the surface of the source material to heat it all.
