Summary: E-beam technology possesses all the tools and characteristics that a quality deposition method requires.
This guide will break down all the essentials that you need to know to understand how e-beam evaporation works and how it’s applied in today’s industries.
Understanding Ebeams
E-beam evaporation is a physical vapor deposition technique that utilizes a centralized electron beam generated from a filament that contains numerous electric and magnetic fields. The ebeam itself is an intense.
Once it strikes a source material, it will then vaporize it within a specially designed vacuum chamber. Note that a vacuum environment is crucial to the entire process. The source material that is placed inside will then be heated through an energy transfer process. At this point, it will then travel throughout the vacuum chamber and then coated on the substrate above the evaporating material. Much of the working distances are 300mm to 1 meter.
Applications
Since e-beam technology has been utilized in a variety of industries, you can only imagine the flexibility and versatility that this process has. PVD thermal evaporation is one of the most widely used technologies out there for deposition processes. Anything from the microchip industry to solar panels, e-beam evaporation can perform it all and do it at temperatures that some technologies would deem too unstable. One the most beneficial aspects of utilizing e-beam technology over others is that it creates a vortex of electron beams that strike the target at high speeds. This creates such a force that the substrate always obtains a high adhesion rate and high quality surface characteristics, as opposed to other methods.
