PVD Pysical Vapour Deposition
Physical Vapor Deposition (PVD) is a family of processes that is used to deposit layers of atoms or molecules from the vapor phase onto a solid substrate in a vacuum chamber. Two very common types of processes used are Sputtering and Electron Beam Evaporation.
PVD Sputter Deposition
Sputtering process involves ejecting material from a “target” that is a source onto a “substrate” (such as a silicon wafer) in a vacuum chamber. This effect is caused by the bombardment of the target by ionized gas which often is an inert gas such as argon. Sputtering is used extensively in the semiconductor industry to deposit thin films of various materials in integrated circuit processing. Anti-reflection coatings on glass for optical applications are also deposited by sputtering. Because of the low substrate temperatures used, sputtering is an ideal method to deposit metals for thin-film transistors. Perhaps the most familiar products of sputtering are low-emissivity coatings on glass, used in double-pane window assemblies. An important advantage of sputtering is that even materials with very high melting points are easily sputtered while evaporation of these materials in a resistance evaporator or Knudsen cell is difficult and problematic.
PVD is an environmentally friendly vacuum coating process with no hazardous by products resulting brilliant decorative finishes with excellent wear and corrosion resistance.
PVD - sputtering coatings can be used in all possible areas:
automotive components, , nautical accessories, handle and locks, medical equipment, glass and ceramics objects, mobile telephone accessories, engineering components, fashion accessories, sports accessories, kitchen accessories, …
Sputtering is preferred for industrial application because of versatility, its widespread use to sputter many materials. The deposition conditions can be controlled by the plasma power and gas pressure, but they are reasonably independent of the substrate geometry.
