Abstract Etch rates of Kapton H polyimide film in SF6- O2plasmas (0.25 torr) were studied as a function of the input gas mixture, the excitation frequency (25 kHz -450 kHz; 13.56 MHz) and the biasing mode.The treated surface was examined by X P S, SEM and contact angle measurement.

  • Oxidation of sulfur hexafluoride - ScienceDirect

    Abstract Although SF 6 is extraordinarily inert toward oxygen, reaction can be initiated by the electrical explosion of extremely small masses of platinum into SF 6 O 2 mixtures. It is shown that chemically trivial amounts of exploding metal can be effective initiators of the SF 6 oxidation.

    History of SF6Chemical Properties of SF6 GasElectrical Properties of SF6 GasSF6 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 SF6 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...
