The localization of special gases is the general trend. Since the introduction of special gases into the Chinese market in the mid-1980s, China's special gas industry has undergone 30 years of development and precipitation. With the continuous accumulation of experience and technological progress, leading enterprises in the industry have achieved breakthroughs in some products, reached the international standard, and gradually realized import substitution, and the localization of special gases has objective conditions. At the demand level, in recent years, China has continuously built a number of 8-inch, 12-inch large-scale integrated circuit production lines, high-generation panel production lines, etc., in order to ensure stable supply, timely service, and cost control, there is an urgent need for the localization of special gases. In addition, in recent years, the state has issued guiding documents such as the "13th Five-Year Plan for the Development of National Strategic Emerging Industries" and the "New Materials Industry Guide", aiming to promote the localization of key materials, including special gases. Therefore, under the influence of multiple factors such as technological progress, demand pull and policy stimulus, the localization of special gases is imperative.
