[PDF] gaz sf6 Optimized O2 Plasma Etching of Parylene C

Without the Sulfr hexafluoride, 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 Sulfr hexafluoride flow, the residuals were effectively removed during the O2 plasma etching.Get price

Silicon Nanostructuring Using insulating gas/O2 Downstram Plasma Etching

Knizikevicius 16 performed a simulation of Si etching in SF 6 /O 2 plasma and found that at 27% O 2, the concentration of F atoms approaches the maximum value. From the two figures 1 and 2, one can conclude that, in our case, the decrease of the etching rate beyond 5% O 2 is not related to the decrease of F radicals concentration in the plasma.Get price
