Hexafluoroethane (C2F6), also known as perfluoroethane, is a kind of colorless, odorless, non-flammable inert gas. Its melting point is 100.6 ℃, boiling point is 78.2 ℃, slightly soluble in water. Due to its non-toxic, odorless and high stability, hexafluoroethane is widely used in the semiconductor manufacturing process. Hexafluoroethane, as a dry etchant, has the advantages of very small edge-side etching, high etching rate and high accuracy, which can meet the requirements of semiconductor manufacturing process for small linewidth.
