Sulfr hexafluoride Optimized O2 Plasma Etching of Parylene C

Here, we proposed an SF 6 optimized O 2 plasma etching (SOOE) of Parylene C, with titanium as the etching mask. Without the SF 6, noticeable nanoforest residuals were found on the O 2 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 SF 6 flow, the residuals were effectively removed during the O 2 plasma etching.Get price

Surface interactions of SO2 and passivation chemistry during

Jan 04, 2011 · Here, the fate of SO 2 at Si and SiO 2 surfaces during etching in SF 6 / O 2 plasmas has been explored using the imaging of radicals interacting with surfaces method. The scattering of SO 2 at Si and SiO 2 surfaces was measured as a function of both the applied rf power and O 2 addition to the plasma. For both surfaces, the surface scattering coefficient ( S) of SO 2 during etching is near unity and is largely unaffected by changing plasma parameters such as power and O 2 addition.Get price
