The rapid development of the electronic information industry has brought broad market space for materials such as electronic gases, and China has also given special attention to their research and industrialization. In the 2008 National Electronic Information Industry Development Fund projects released by the Ministry of Industry and Information Technology, the nitrogen trifluoride special gas project of the internationally leading 718 Institute's Peric Technology Park received support from this fund.
High-purity nitrogen trifluoride is a special gas used in the microelectronics industry, which can "etch" grooves as small as tens of nanometers on integrated circuit boards, making the core components of electronic products smaller and smaller, and allowing various digital products such as mobile phones, computers, and MP3s to become more compact. At the same time, it can also be used as a cleaning gas. During the production of liquid crystal displays, since there are some impurities in the surrounding environment that are difficult to clean by conventional methods, nitrogen trifluoride can play a significant role, creating an almost zero-pollution environment for the production of liquid crystal displays. In addition, because high-purity nitrogen trifluoride has minimal harm to the Earth's ozone layer, it is used by many countries and regions to replace greenhouse gases such as sulfur hexafluoride (SF6), hexafluoroethane (C2F6), and carbon tetrafluoride (CF4) listed in the Montreal Protocol and the Kyoto Protocol.
With the development of the microelectronics industry, the demand for high-purity nitrogen trifluoride gas will increase worldwide. It is predicted that in the next ten years, the demand for nitrogen trifluoride in the semiconductor and chip industries will increase at an annual rate of 25%, and the requirements for the purity of nitrogen trifluoride will also become higher and higher, which means that this product will have broader development space in the future.
The purity of nitrogen trifluoride gas produced by Feiyuan Technology has reached 99.995%. Compared with the nitrogen trifluoride gas production technology of the United States and Japan, Feiyuan Technology's nitrogen trifluoride technology is superior in terms of safety and economy. The production of high-purity nitrogen trifluoride gas has formed an industrial scale, with an annual production capacity of 1,000 tons, and the products are exported to the United States, Japan, and other countries and regions.
