Science popularization an electronic gas industry, known as the "blood" of the electronic industry, especially in the semiconductor field, its demand share is second only to large silicon chips.
1) Rapid growth of downstream demand for electronic gas
The downstream applications of electronic gas are mainly in the fields of integrated circuit, panel, photovoltaic, etc., and the demand accounts for more than 90%. The electron gas penetrates the processes of thin film, etching, doping, vapor deposition and diffusion.
In the field of integrated circuits, the sales volume of Chinese mainland is 20.27% faster than that of the rest of the world.
In terms of panel manufacturing, China's panel production capacity has increased rapidly in the world.
With the continuous expansion of downstream demand, the scale of China's E-Gas has increased from 3.9 billion in 2010 to 12.1 billion in 18 years, and is expected to reach 23 billion in 2024. Superimposed on the process of domestic substitution, the growth rate of domestic enterprises will be faster.
2) Acceleration of domestic substitution
In the domestic market, air chemical, Linde Group, liquefied air and Dayang Riyan acid control 88% of the market, while domestic enterprises only own 12% of the market.
Special gas as a key material, under the support of national policy, domestic Yake technology, China Shipbuilding Industry 718
The Institute, Huate gas, Haohua technology and other enterprises have made breakthroughs and gradually realized import substitution.
3) Sorting out individual stocks of industrial chain
Huate gas: take the lead in import substitution of nearly 20 products such as high-purity carbon tetrafluoride, high-purity hexafluoroethane, photolithography gas and high-purity carbon dioxide, and enter the supply chain of SMIC international, Huahong and Changcun.
Haohua Technology: as a leading supplier of nitrogen trifluoride in China, self-developed hydrogen selenide and green nitrogen tetroxide realize import substitution, and have a leading advantage in the field of military products.
Jinhong gas: an important supplier of special gas and bulk gas in East China, and has established cooperative relations with Lianxin integration, China Resources Microelectronics, Huali microelectronics, silicon technology, and Shilan micro.
Heyuan gas: a well-known private professional gas enterprise in Central China, whose products cover industrial gas, food grade liquid nitrogen, medical oxygen, etc.
Yak Technology: the subsidiary company KEMET is the leader of domestic fluorine-containing electronic gas, and its customers cover Xidian group, Pinggao group, Shandong taikai, xindongbei, Siyuan electric, abb, etc.
Nanda optoelectronics: the acquired feiyuan gas is a major supplier of nitrogen trifluoride and sulfur hexafluoride from TSMC, SMIC international and BOE.
