GE sf6 Evacuation

OES analysis was performed to analyze the first wafer effect in the gate etching by high density plasma etcher. The first wafer in a lot shows smaller CD gain as well as shorter endpoint time compared to the rest of the wafers in the lot when the lot was etched after long idle status of the high density plasma etcher. This effect should be cleared for the manufacturing of sub-100nm device. In ...

  • Green Gas for Grid - g3 - SF6 Free Solutions

    SF 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

    Dec 09, 2016 · The SF6 gas handling units are additionally equipped with an oil-free suction pump. Thus it is possible to recover the SF6 from the gas compartment down to a final vacuum of less than 1 mbar. A powerful vacuum pump allows the evacuation of air from the circuit breaker to less than 1 mbar to prevent mixing of air with SF6 gas during the refilling process.

  • Gas-Insulated Substations - GIS

    SF6 is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the SF6 will not condense into a liquid at the lowest temperatures the equipment experiences. SF6 has two to three times the insulating ability of air at the same pressure. SF6 is about 100 times better than air for interrupting arcs.
