稀土反制立竿见影！ASML对我们销售额跌20%，国产光刻机撑起半条生产线

Core Viewpoint - The global semiconductor industry is undergoing significant adjustments due to intensified U.S. export controls aimed at limiting China's access to advanced lithography machines, which poses a direct threat to the production stability of Chinese companies [2][4]. Group 1: U.S. Export Controls - The U.S. government has updated regulations multiple times, prohibiting the export of EUV machines and extending restrictions to maintenance services and spare parts, creating potential risks for installed equipment [2]. - ASML, the primary supplier of high-end lithography machines, has acknowledged the challenges posed by these restrictions, particularly regarding the maintenance of EUV systems that rely on rare earth elements [8][10]. Group 2: China's Response and Self-Reliance - Chinese technology companies are making steady progress in independent research and development of lithography machines, with firms like Shanghai Micro Electronics achieving testing applications for 28nm DUV technology [4]. - The Chinese government is investing heavily in semiconductor R&D, with funding expected to exceed previous levels by 2025, focusing on talent development and ensuring production continuity under external pressures [4][12]. Group 3: Rare Earth Elements as a Leverage - China has implemented new regulations on rare earth elements, requiring export licenses for 12 types and extending to products containing Chinese rare earths, directly responding to U.S. rules [6][10]. - The global supply chain for rare earths is heavily reliant on China, which accounts for 70% of mining and 90% of processing, prompting international companies to reassess supply chain security [6][12]. Group 4: Impact on Global Supply Chains - ASML has stockpiled rare earth inventories to mitigate short-term impacts but acknowledges potential long-term delays in production due to reliance on these materials [8]. - Major companies like Intel and Samsung are auditing their product components to avoid compliance risks, while Chinese firms are accelerating domestic replacements, leading to significant improvements in production yields [8][22]. Group 5: Strategic Industry Comparisons - The U.S. focus on technology controls contrasts with China's resource-based strategy, creating a complementary response to the ongoing trade tensions [14]. - Chinese companies are expected to achieve breakthroughs in EUV technology by 2025, with collaborative efforts from academic institutions enhancing the development process [14][20]. Group 6: Global Industry Dynamics - The semiconductor conflict highlights the limitations of unilateralism, as the U.S. attempts to coordinate with allies have not fully anticipated the repercussions of China's resource management [20]. - China's recent regulatory adjustments are seen as a rational response, with a focus on maintaining domestic production while pushing for fair global supply chains [22].
