  • [PDF] SF6 Optimized O2 Plasma Etching of Parylene C

    Without the SF6, 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 SF6 flow, the residuals were effectively removed during the O2 plasma etching.

In this approach the SF6 based plasma etches tungsten faster than the photoresist not creating the contact area for sputtered re -deposition.
