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

Without the insulating 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

Detection of sulfur dimers in Sulfr hexafluoride and Sulfr hexafluoride/O2 plasma-etching

Sulfur dimers were detected in sulfur‐hexafluoride plasma‐etching discharges using optical emission spectroscopy and laser‐induced fluorescence spectroscopy. Dimer densities were estimated to be on the order of 1013/cm3 and appear to decrease rapidly with increasing oxygen content in the discharge.Get price

SF Maintenance Equipment Fundamentals

Oil-based compressors rely heavily on oil traps, scrubbers and filters to remove compressor oil from the SF 6. Arguably, some oil will remain in the gas and transfer to the GIE. Oil-free compressors contain oil in the crankcase, but provisions are made to keep the oil from seeping into the compression chamber.Get price

VALIDATION METHODS OF gaz sf6 ALTERNATIVE GAS

Additionally, as sf 6 has a very low boiling point (-64°C at 1 bar), it is possible to use it alone for medium voltage applications where the minimal temperature of use is generally comprised between -25°C and -5°C and where the filling pressure does not exceed 2 bars. As it is not possible to perform tests on the whole rangeGet price
