Linear e beam sources are also available.
Electron beam evaporation system.
Pvd products complete thermal and electron beam evaporation systems are designed to meet the customer s specific deposition needs.
Pellets of au and vaporize it within a vacuum environment.
Electron beam evaporation or e beam evaporation is a powerful physical vapor deposition process that allows the user to evaporate materials that are difficult or even impossible to process using standard resistive thermal evaporation.
Four pockets 4cc for electron beam evaporation no sweep.
Some of these materials include high temperature materials such as gold used as an electrical contact in solar cell applications or ceramics like silicon dioxide for optical films among many others.
E beam electron beam evaporation is a thermal evaporation process and along with with sputtering is one of the two most common types of physical vapor deposition pvd.
E beam evaporation provides for the direct transfer of a larger amount of energy into the source material enabling the evaporation of metal and dielectric materials with very high melting temperatures such as gold and silicon dioxide respectively.
Atc e and atc orion 8e cylindrical uhv style chambers and atc 2030 and atc 2036 hv style box coaters.
High voltage is applied between the filament and the hearth to accelerate these liberated electrons towards the crucible containing the material to be deposited.
During an e beam evaporation process current is first passed through a tungsten filament which leads to joule heating and electron emission.
The e beam system has the following features.
These systems can contain single or multiple thermal sources multi pocket e beam sources and multi gun sources as required.
Our evaporation systems come complete with power supplies sweep controls and quartz crystal deposition rate monitors for closed loop feedback control.
The electron beam evaporation system is available in two different configurations.
This configuration can be provided with a gate valve between the two chambers to be used as a load lock to keep the e beam source and the evaporation pockets in vacuum while substrates are loaded and unloaded.
Electron beam e beam evaporation is a time tested deposition technology for producing dense high purity coatings.
E beam evaporation is a physical vapor deposition pvd technique whereby an intense electron beam is generated from a filament and steered via electric and magnetic fields to strike source material e g.
Ferrotec offers a complete line of electron beam evaporation components ranging from the temescal e beam guns with a rich history that goes back to the first e gun design patents to our unique center mount guns with an integrated feedthrough that puts all connections outside of the vacuum.
Aja international atc e series electron beam evaporation systems are available in the following versions.
Upon striking the evaporation material the electrons will lose their energy very rapidly.
The generated electron beam is accelerated to a high kinetic energy and directed towards the evaporation material.
