[PDF] Sulfr hexafluoride Optimized O2 Plasma Etching of Parylene C

Without the sf6 gas, noticeable nanoforest residuals were found on the O2 plasma etched Parylene C film, which was supposed to arise from the micro-masking effect of the sputtered titanium metal mask. By introducing a 5-sccm insulating gas flow, the residuals were effectively removed during the O2 plasma etching.Get price
