[PDF] Cryogenic etching of silicon with Sulfr hexafluoride/O2/SiF4 plasmas

Cyrogenic etching of silicon is envisaged to enable better control over plasma processing in microelectronics and to limit plasma induced damage for features beyond the 14 nm technology node. We here present results of plasma modelling for a gaz sf6/O2/SiF4 plasma and of molecular dynamics (MD) simulations for predicting surface interactions, together with results of etch experiments for validation.Get price

gaz sf6/oil dielectric for power transformers - NASA/ADS

The potential for providing a superior gas-oil insulating and cooling system for liquid filled transformers was evaluated. The potential benefits of using the electronegative gases, sulfur hexafluoride, sf 6, or hexafluorethane, C2F6, in place of nitrogen gas normally used in gas-oil filled transformers were examined. It is shown that the gaz sf6 oil combination appeared satisfactory as anGet price

Sulfr hexafluoride Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of gaz sf6Chemical Properties of sf6 gas GasElectrical Properties of sf 6 GasSulfr hexafluoride or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that Sulfr hexafluoride gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very r...Get price
