It is the equipment to provide the electron beam vertically to the evaporate surface using the electron beam gun, and it is used in the process of optical multi-layer films

This is the process micro electro mechanical system (MEMS) known as the electron beam evaporation process Physical Vapor Deposition (PVD)

The deposition process is used to open the data in the source and send those data to the basal board and also to form thin films or coating.

Because this is inexpensive regarding the material cost and exhibits rather low process risk, PVD process is the chemical vapor deposition generally used for metal eposition.

The process applying the deposition of thin films conducts modification with various kinds of surfaces wanted by the industry in order to provide data to the electronic industry for semicon doctor growth, reflection needing properties to the aerospace, environment to the permeability optics, surface protection from the board corrosion, and also thermal and chemical barrier coating.
