电子气体行业深度报告：电子气体：半导体需求有望加速扩张，国产替代或重塑供给格局

Investment Rating - The report rates the industry as "Outperforming the Market" [6] Core Insights - The electronic gas industry is crucial for semiconductor manufacturing, with high product certification barriers. It is divided into bulk gases and specialty gases, with the latter being more technically intensive and having over 110 types used in semiconductor processes [1][3] - Demand for electronic gases is expected to accelerate due to the expansion of wafer manufacturing capacity and technological iterations, particularly driven by the increasing need for AI chips in data centers and edge devices. The Chinese electronic specialty gas market is projected to reach 42 billion yuan by 2030, while the bulk gas market is expected to reach 28.8 billion yuan [2][3] - The supply chain is being reshaped by domestic substitution, with local manufacturers currently covering only 20%-30% of the required types for integrated circuit manufacturing. The domestic production rate for electronic specialty gases is expected to reach 25% by 2025 [3] Summary by Sections 1. Electronic Gases: Key Materials in Wafer Manufacturing - The electronic gas industry has significant entry barriers due to the high purity requirements and complex production processes. The industry is categorized into bulk gases and specialty gases, with specialty gases being high-value and requiring stringent purity controls [1][15] - The purity standards for electronic gases start at 5N (99.999%) and can go up to 6N (99.9999%) or higher, with strict control over impurities [17][46] 2. Demand Side: Capacity Expansion and Technological Iteration - The Chinese semiconductor materials market is projected to grow, with electronic specialty gases accounting for approximately 13% of the wafer manufacturing materials. The market size is expected to increase from 9.2 billion yuan in 2016 to 19.5 billion yuan in 2024 [48][54] - The global wafer manufacturing equipment spending is expected to reach 374 billion USD from 2026 to 2028, with China leading in investment [62][68] 3. Supply Side: Domestic Substitution Reshaping Supply Chain - The global electronic gas market is dominated by a few major players, with local manufacturers still in the early stages of achieving self-sufficiency. The potential for domestic suppliers to accelerate their validation processes is increasing due to external supply chain pressures [3][4] - The report emphasizes the long-term value of the electronic gas sector, driven by demand-side growth and supply-side restructuring [3] 4. Investment Recommendations - The report suggests focusing on leading companies in the electronic bulk gas and specialty gas sectors that have core competitive advantages [3][4]
