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

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.

Sputter deposition

Sputter deposition is a physical vapor deposition method of thin film deposition by the phenomenon of sputtering. This involves ejecting material from a "target" that is a source onto a "substrate" su
Physical vapor deposition
…which the material transitions from a condensed phase to a vapor phase and then back to a thin-film condensed phase. The most common PVD processes are sputtering and evaporation. PVD is used in the manufacturing of items which require thin films for optical, mechanical, electrical, acoustic or chemical functions…
