Application of SF4:
carbon tetrafluoride is the largest amount of plasma etching gas in the microelectronics industry at present. It is a mixture of high purity gas and high purity oxygen of carbon tetrafluoride. It can be widely used in the etching of silicon, silicon dioxide, silicon nitride, phosphorous silicon glass and tungsten film materials.
For silicon and silicon dioxide systems, the selectivity of 45:1 can be obtained by adjusting the ratio of the two gases when using the reactive ion etching of cf4-h2, which is very useful for etching the silicon dioxide film on the polycrystalline silicon gate.

It is also widely used in surface cleaning of electronic devices, production of solar cells, laser technology, gas phase insulation, cryogenic refrigeration, leakage testing agent, control of space rocket attitude, and detergent in printing circuit production.
