  • SAFE WORKING PRACTICES FOR SF6 GAS INSULATED

    1. SF6 gas is odorless, tasteless, colorless, nontoxic and extremely stable in its pure state. 2. SF6 gas is heavier than air and tends to collect in low places. While SF6 is nontoxic, it can exclude oxygen and hence can cause suffocation. When entering a pit area beneath equipment or a vessel that has previously contained SF6 an oxygen test

  • Si/SiO2 etching in high density SF6/CHF3/O2 plasma

    Mar 06, 1998The introduction of oxygen plasma increases the F-containing gas dissociation efficiency and thus increases the amount of F-containing active species in the plasma 13, 14. However, an excessive amount of oxygen may cause plasma dilution, oxygen adsorption, and Si oxidation, which will slow down the-etching .
