  • Mechanism of silicon etching by a CF4 plasma: Journal of

    Jun 04, 1998The mechanisms for the reactive ion etching of silicon by CF 4 plasma are investigated. A model is proposed whereby silicon is etched by chemical reaction with free fluorine to produce a volatile species, and also by physical sputtering. The chemical etching is shown to be enhanced by ion bombardment of the reacting surface. This etching process, together with a model for cracking CF 4 in

  • Method of etching anti-reflection coating. - AMERICAN

    Plasma etching of polyimides is discussed by Scott et al. in Journal of Vacuum Science and Technology, A8, May/June 1990, pp. 2382-2387. Scott used a mixture of CF4 and O2 and found that the addition of CF4 increased the etch rate of the polyimide as compared to the rate obtained with only O2.
