Sputtering

Sputtering is a physical vapor deposition (PVD) process which uses a material target and a source of energy that can be either a dc or rf (radio frequency) discharge to create a vapor, releasing layers of material onto a substrate. This process is used to deposit thin films of metals, nitrides, and oxides and it is widely used in applications such as optical coatings, and microelectronics. Sputtering also provides benefits such as low deposition rates, excellent surface coverage, and uniform material depositions, making it an ideal choice for creating thin films. Additionally, it is an environmentally friendly process due to its low temperature and low pressure requirements. Sputtering is therefore a major industrial process which can be utilized for a wide range of applications.
