WebNov 22, 2005 · Reactive sputtering is the sputtering of an elemental target in the presence of a gas that will react with the target material to form a compound. In one sense all sputtering is reactive because there are always residual gases in the chamber that will react with the sputtered species. Removing atoms by sputtering with an inert gas is called ion milling or ion etching. Sputtering can also play a role in reactive-ion etching (RIE), a plasma process carried out with chemically active ions and radicals, for which the sputtering yield may be enhanced significantly compared to pure physical sputtering. Reactive ions are frequently used in secondary ion mass spectrometry (SIMS) equipment to enhance the sputter rates. The mechanisms causing the sputt…
