NF₃

Nitrogen Trifluoride

The chemical formula of nitrogen trifluoride is NF₃. It is a colorless, odorless and stable gas at normal temperature. It is a strong oxidant. High purity nitrogen trifluoride has excellent etch rate and selectivity, and it is also a very good cleaning agent. Jinhong can provide you with high-purity nitrogen trifluoride gas to improve your semiconductor process.

Process

Nitrogen trifluoride is prepared by the direct fluorination of ammonia. It may also be obtained by electrolysis of molten ammonium bifluoride or by direct combination of the elements nitrogen and fluorine using an electrical discharge at low temperatures.

Gas	Nitrogen trifluoride
CAS No.	7783-54-2
Purity	99.99%

Applications

Silicon Processing

Nitrogen trifluoride is used as a high speed, selective etchant in silicon processing. It has been used to etch silicon, polysilicon, silicon nitride and silicon oxide as well as refractory metals and silicides.

Industrial

Nitrogen trifluoride is sometimes used as the fluorine source in HF /DF chemical lasers. Nitrogen trifluoride is used as a fluorinating agent. Nitrogen trifluoride is also used for fibre treatment. F
