  • An XPS study of photoresist surfaces in SF6 O2 r.f

    Jul 01, 1991In the standard conditions used with a tungsten cathode, actinometry measurements show that the relative concentration of the fluorine atoms is quite constant over a wide range of SF6-O2 mixtures from 0 to 80% of oxygen in SF6. As a result, the surface of the photoresists is largely fluorinated in such conditions.Cited by: 4

  • Infrared spectroscopic parameters of COF2, SF6, ClO, N2

    Nov 01, 1992Experimental measurements of SF6 air broadening are also needed, but it may be difficult to determine reliable values because of the high density of lines in the spectrum. Tejwani and Fox 6 presented calculated self-broadened linewidths of SF6 FZ rotational species as a function of m at temperatures of 100, 200, and 300 K.Cited by: 13

  • Fourier transform infrared spectroscopy quantitative

    Feb 05, 2015Sulfur hexafluoride (SF 6) gas is widely applied as an electrical insulator as well as an arc-quenching medium in gas-insulated switchgear (GIS).Pure SF 6 is a colorless, tasteless, non-poisonous, and non-combustible inert gas, the dielectric strength of which is thrice that of air at atmospheric pressure .SF 6 gas produces minimal decomposition components under normal operation circumstances.

  • Atmospheric SF6: Trends, Sources, and Prospects

    Sulfur hexafluoride (SF6) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, SF6 will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought SF6 into the climatic impact discussion aimed at reduction
