WebApr 1, 1993 · Abstract. Tungsten etching has been studied in audio frequent plasmas with NF 3 -O 2 and SF 6 -O 2 mixtures. The influence of etch mode, gas flows, pressure and power has been investigated. It is possible to etch tungsten chemically but large concentrations of free fluorine are needed. These are supplied more easily by NF 3 than by SF 6. WebReactive ion etching (RIE) is a type of plasma etch technology used in specialty semiconductor markets for device manufacturing.

Etching Silicon with Plasma - Reactive Ion Etching (RIE)

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… WebReactive ion etching (RIE) is a plasma etching process that adds a charge to the part being etched which induces a directional component to the etching process.
