Nl. Ovchinnikov et al., USE OF CL-2-DISCHARGE CONDITIONS(AR MIXTURES IN ETCHING SILICON ON THE CATHODE UNDER DC GLOW), Inorganic materials, 34(5), 1998, pp. 417-418
Dry etching of silicon was studied in chlorine + argon mixtures under
de glow-discharge conditions, with the sample to be etched placed on t
he cathode. The etching rate depends on the composition of the plasma
gas and peaks at 40 vol % Ar.
