Physical vapor deposition (PVD) is a thin film deposition process in which atoms or molecules of a material are vaporized from a solid source in high vacuum and condense on a substrate. The PVD processes can be used to deposit films of metals, alloys, metal oxides, and some composite materials on a variety of substrates.
