Octafluoropropane
八氟丙烷(C3F8)是一種無色、無味、不可燃的惰性氣體。八氟丙烷熔點為-183.0℃，沸點為-36.7℃，難溶于水。電子級高純八氟丙烷應用在半導體器件制造過程中，與氧氣的混合氣可用作等離子蝕刻氣體。
Octafluoropropane (C3F8) is a kind of colorless, odorless, non-flammable inert gas. Its melting point is 183.0 ℃, boiling point is 36.7 ℃, poorly soluble in water. Electronic grade octafluoropropane is used in semiconductor materials and semiconductor device manufacturing. The mixture of octafluoropropane and oxygen is used as plasma etching material, which can selectively interact with the metal matrix of silicon wafer.
