Vacuum deposition

Vacuum deposition is a group of processes used to deposit layers of material atom-by-atom or molecule-by-molecule on a solid surface. These processes operate at pressures well below atmospheric pressu

Physical vapor deposition, sometimes called physical vapor transport, describes a variety of vacuum deposition methods which can be used to produce thin films and coatings on substrates including meta

…structures. Multiple layers of different materials can be used, for example to form optical coatings. The process can be qualified by the vapor source; physical vapor deposition uses a liquid or solid source and chemical vapor deposition uses a chemical vapor. The vacuum environment may serve one or more purposes…
Inside the plasma-spray physical vapor deposition (PS-PVD) chamber ceramic powder is introduced into the plasma flame, which vaporizes it and then condenses it on the (cooler) workpiece to form the ceramic coating.
This figure gives a simple illustration of the process of PVD where the desired deposited gas molecules enter the chamber after being condensed, and then are condensed once again onto a thin film, such as the anisotropic glass.
