With the development of semiconductor industry technology and the refinement of component in integrated circuits, plasma etching technology has been widely used in semiconductor manufacturing process due to its advantages such as anisotropic etching, process compatibility and few etching residues. The etching gas manufactured by our company is usually fluoride gas, including nitrogen trifluoride, perfluorobutadiene, Hexafluoroethane, octafluoropropane, etc.
