Sputtering process. Factors on which sputtering process depends.

Sputtering process. Sputtering is a phenomenon of ejecting microscopic particles from a solid surface by energetic particles of a plasma or gas. The sputtering process begins inside a vacuum chamber, where the target material, typically referred to as the “sputtering target,” is placed. In a typical sputtering deposition process, a chamber is first evacuated to high vacuum to minimize the partial pressures of all background gases and potential contaminants. The substrate, which will receive the thin film coating, is positioned facing the target. Another process option is Reactive Sputtering, which utilizes a non inert gas, such as oxygen, in combination with an elemental target material, such as silicon. ion-beam sputtering, reactive sput- tering - but all these are variants of the same physi- cal phenomenon. 2. , the exact working point in the reactive gas partial pressure – sputter deposition rate plane depends on the history of the target.
