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 (or RIE) is a simple operation and an economical solution for general plasma etching. A single RF plasma source determines both ion density and energy. Our …
