US Sharpens Restrictions on China’s Chip Industry, Fueling Tech Rivalry
The United States has once again escalated its stance on China’s semiconductor industry, imposing a new wave of restrictions designed to limit Beijing’s access to advanced chip technology. These measures, inaugurated on Monday, mark the third significant crackdown in three years and encompass a wide array of controls targeting semiconductor manufacturing equipment, software tools, and high-bandwidth memory (HBM) chips critical for artificial intelligence (AI). The initiative also adds 140 more Chinese companies to the Commerce Department’s Entity List. This blog examines the key measures enacted and their potential implications for global players and the U.S.-China tech rivalry.
Stricter Controls on Semiconductor Equipment
One of the central aspects of the crackdown is the restriction on specific semiconductor manufacturing equipment necessary for producing advanced-node integrated circuits. These tools include etching, deposition, lithography, ion implantation, annealing, metrology, inspection, and cleaning equipment.
These controls are poised to affect both U.S. and non-U.S. companies operating in the sector, from Lam Research, KLA Corp, and Applied Materials to Dutch equipment maker ASM International. The broad scope of these restrictions aims to inhibit China’s capabilities in producing state-of-the-art chips essential for applications like AI and high-performance computing.
Software Tools Face New Scrutiny
The new restrictions extend to advanced software tools that aid in the development or production of integrated circuits. Software that enhances the efficiency of cutting-edge machinery—or even enables older machines to produce more sophisticated chips—is now firmly in the crosshairs.
This could impact global players such as Siemens, the parent company of Mentor Graphics, which specialises in creating design software for semiconductor production. The U.S. government plans to stifle the development of advanced chip manufacturing processes by restricting critical software advancements from being accessible to Chinese firms.
High-Bandwidth Memory Restrictions
High-bandwidth memory (HBM), used predominantly in AI chips, is another focus area. The newly imposed rules restrict the export of technology akin to HBM2 and higher, a product primarily manufactured by companies like South Korea’s Samsung and SK Hynix, as well as U.S.-based Micron Technology.
Samsung is expected to be hit the hardest since analysts estimate that 30% of its HBM chip revenue currently comes from China. This move will not only challenge Chinese firms relying on HBM for their AI training models but could also create significant ripple effects across global supply chains for AI-driven industries.
Expansion of the Entity List
A substantial portion of the new strategy involves adding 140 Chinese companies to the Commerce Department’s Entity List. This list blocks access for named entities to U.S. technology unless explicit licences are issued. Companies newly restricted include semiconductor fabrication plants, semiconductor tool manufacturers, and private equity investment firms aligned with Beijing’s chip agenda.
Firms such as Wise Road Capital, Wingtech Technology, and JAC Capital have now been placed on this list. The U.S. government asserts that these companies contribute to China’s advanced chip development goals, posing risks to U.S. and allied national security.
Foreign Direct Product Rule Expansion
A critical and somewhat unprecedented measure is the extension of the Foreign Direct Product (FDP) rule. This expansion affects chipmaking equipment produced by international manufacturers such as those in Israel, Malaysia, South Korea, and Taiwan, limiting their exports to Chinese entities.
The United States has exempted its key allies, Japan and the Netherlands, from this rule to support their role in limiting China’s access to advanced semiconductor technology. The U.S. is also tightening thresholds regarding U.S.-originated content, further broadening its jurisdiction over foreign products shipped to Chinese companies.
The FDP rule will apply to the 16 companies on the Entity List deemed most critical to China’s semiconductor ambitions, further complicating China’s access to foundational chipmaking equipment from overseas.
Semiconductor Industry and Geopolitical Shifts
The latest measures signify an aggressive escalation in Washington’s efforts to maintain technological supremacy over Beijing. By targeting critical tools, software, and key components like HBM chips, the U.S. seeks to stall China’s AI advancements and overall tech capabilities.
For the global semiconductor industry, these restrictions add to an already strained supply chain. International equipment manufacturers caught in the crossfire could see dwindling sales in one of their largest markets. Additionally, countries like South Korea, which heavily depend on Chinese revenues, may face economic setbacks.
A Technology Cold War?
This new wave of restrictions underscores a deepening rift in technological ties between the U.S. and China. By crippling China’s ability to access advanced semiconductors, Washington is not just seeking a competitive edge but acting to safeguard national security. Simultaneously, these moves could accelerate China’s resolve to achieve self-sufficiency in chip manufacturing, propelling its investment in homegrown technologies.
Heightened geopolitical tensions are now reshaping the semiconductor industry, with ripple effects impacting nations and enterprises well beyond the immediate U.S.-China conflict.
