process, either CF-containing FFCs are used or simply Sulfr hexafluoride. In etch processes, on average, more of the FFCs is utilized, so less of the original FFC exits the chamber unreacted and is emitted into the atmosphere. Of the total FFC emissions from semiconductor manufacturing, roughly <40 percent (MMTCE basis) result from plasma etching steps.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
