Introduction To Vacuum Coating Machine

The substrate to be coated is called the substrate, and the material to be coated is called the target. The substrate and the target are in the same vacuum chamber.
Evaporation coating generally heats the target so that the surface components are evaporated in the form of atomic groups or ions. And it settles on the surface of the substrate, and forms a thin film through the film forming process (scattered points-island structure-vagal structure-layered growth). For sputtering coating, it can be simply understood as bombarding the target with electrons or high-energy lasers, and sputtering the surface components in the form of atomic groups or ions, and finally depositing on the surface of the substrate, undergoing the film forming process, and finally forming a thin film.
