[0002] PVD technology involves using physical methods under vacuum conditions to vaporize the surface of a material source (solid or liquid) into gaseous atoms or molecules, or partially ionize it into ions. Through a low-pressure gas (or plasma) process, a thin film with specialized properties is deposited on the substrate surface. PVD is a major surface treatment technique. PVD coating technologies are primarily categorized into three types: vacuum evaporation, vacuum sputtering, and vacuum ion plating. The main methods of physical vapor deposition include vacuum evaporation, sputtering, arc plasma, ion plating, and molecular beam epitaxy. Corresponding vacuum coating equipment includes vacuum evaporation, sputtering, and vacuum ion plating machines. With advancements in deposition methods and technologies, physical vapor deposition can deposit not only metal and alloy films, but also compounds, ceramics, semiconductors, and polymer films.
