  • Gas-insulated Switchgear (GIS) Testing - OMICRON

    The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (SF6) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS. The characteristics of the SF6 gas also allow the extinction of arcs which can occur during disconnection of live contacts.

  • Low temperature etching of Si in high density plasma

    1995-2-1Low temperature etching of Si with SF 6 has been studied, using a DECR system and a special Helicon type plasma source. In contrast to the current understanding of low temperature etching, we did not observe a “freezing” of the lateral etching reaction, but obtained isotropic etch profiles, even at temperatures below −120& C. Anisotropic etch profiles are obtained by an addition of O 2.
