Electronic Special Gas Development Trend

  With the development of the electronic industry, China's special gas rose gradually in the 1980s. Although it developed rapidly, the special gas products of domestic manufacturers are still single compared with those of foreign countries, and the level is not high. In China's high-end fields such as integrated circuits, display panels, photovoltaic energy, optical fiber and fiber optic cable, large overseas gas companies have occupied more than 80% of the market share, especially in cutting-edge applications such as extremely large scale integrated circuits and new display panels, there is a large space for import substitution.

  In recent years, with the experience accumulation, nate gas industry technology progress and policy influence, has gradually realize some products of import substitution, estimated in the future in the domestic industrial upgrading process requires extensive use of special gas, and its raw materials in domestic is readily available, so the traditional foreign company production and import sales model has failed to keep pace with the pace of domestic special gas mass production, is expected to China's special gas will be a lot of localization. In terms of data, Air Product accounts for 25 percent, while Praxair and Linde together account for 25 percent and Air Liquid for 23 percent.

  Electronic gas is an indispensable raw material in the production of microelectronics and optronics, such as vlsi, LCD, LED, solar cell, optical fiber, etc. It is widely used in thin film, etching, doping, vapor deposition, diffusion and other processes. For example, nearly 50 different types of electron gases are used in the manufacture of vlsi wafers.

  In recent years, with the rapid development of China's vlsi, LCD, LED, photovoltaic power generation and other industries, the annual growth rate of electronic gas demand has always remained above 30%, and the huge market potential makes the international electronic gas giants full of confidence in China's electronic gas market.
