[PDF] Anisotrapic Reactive Ion Etching of Silicon Using SF 6

Reactive ion etching of silicon in an RF parallel plate system, using sf6 gas/O2/CHF3, plasmas has been studied. Etching behavior was found to be a function of loading, the cathode material, and the mask material. Good results with respect to reproducibility and uniformity have been obtained by using silicon as the cathode material and silicon dioxide as the masking material for mask designs where most of the surface is etched.Get price
