sf6 gas 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

The primary workhorse for these industrial applications is our low pressure liquefaction carts for large volumes of gaz sf6 gas, (greater than 100 lbs.). These carts find use in chambers, gas insulated pipelines and large circuit breakers transformers. The carts are completely self-contained skid-mounted units and are able to fully evacuate, liquefy, vaporize, purify and send gas back to the enclosure. They are available for stationary service or for mobile trailer applications.Get price

Oxidation of sulfur hexafluoride - ScienceDirect

Clearly, the gaz sf6 oxidation must be intrinsically very much slower than the methane pyrolysis. It would appear that the lower rates of Sulfr hexafluoride-O2 reactions, even at very high temperatures, drastically influence the product profiles and the extent of per- manent energy abstraction. This does not appear to be related to the small mass of the explodedGet price

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Aug 02, 2017 · Abstract. Cycles of inductively coupled Sulfr hexafluoride/O2plasma with low (9%) and high (90%) oxygen content etch segments are used to produce up to 46.6 µm-deep trenches with 5.5 µm-wide openings in single-crystalline 4H-SiC substrates. The low oxygen content segment serves to etch deep in SiC whereas the high oxygen content segment serves to etch SiC at a slower rate, targeting carbon-rich residues on the surface as the combination of carbon-rich and fluorinated residues impact sidewall profile.Get price
