What's Happening?
Chris Miller, a nonresident senior fellow at the American Enterprise Institute, has co-authored a report titled 'No Gas, No Chips: Mapping the Choke Points Behind Chip Manufacturing.' The report reveals that the $1 trillion semiconductor industry relies
on a $5 billion specialty gases and chemicals sector, which has received insufficient attention. A significant portion of the production capacity for fluorinated gases, crucial for advanced chip manufacturing, is concentrated in East Asia, with China holding roughly half to three-quarters of the global capacity. This concentration extends to the mineral roots of these gases, such as fluorspar, tungsten, and germanium, where China also dominates production and refining. The report identifies six key risks arising from this dependency: potential capacity shortfalls, single-node fragility in production lines, export bans on finished gases or upstream feedstocks, purity and qualification lock-ins, and regulatory pressures on these gases. Despite the U.S. CHIPS Act allocating substantial funds to fabrication incentives, only a much smaller investment has been directed towards materials and supply-chain projects, leading to increased U.S. reliance on imported materials as domestic chip production grows.
Why It's Important?
The U.S. semiconductor industry's heavy reliance on China for specialty gases and their raw materials poses a significant national security and economic risk. As U.S. demand for these gases is projected to rise by 30% to 65% by 2030 due to new fab constructions, the existing dependency could be exacerbated. China's state-directed financing and industrial policies have enabled it to build substantial production capacity, often exceeding global demand, which drives down prices and deters Western investment in new production. This market distortion makes it structurally unprofitable for Western producers to expand, further entrenching China's leverage. Should China impose export controls or experience production disruptions, U.S. chip manufacturing could face severe delays, price spikes, and even shutdowns, impacting various sectors from defense to consumer electronics. The report underscores that while the U.S. has focused on chip manufacturing, the critical chemical inputs have been largely overlooked, creating a strategic vulnerability.
What's Next?
The report suggests several policy options for the U.S. to mitigate these dependencies. These include mapping dependencies down to the mineral root to gain better visibility into the supply chain, securing the tier below the gases by focusing on minerals like fluorspar, tungsten, and germanium, and prequalifying allied 'second sources' for critical gases to ensure alternative suppliers are ready in a crisis. Additionally, establishing a strategic reserve of critical minerals, implementing trade measures to counter subsidized overcapacity from China, and deepening sourcing interdependence with allies like Canada, Europe, Japan, and Mexico are recommended. These steps aim to reduce China's influence on the specialty gases essential for chip manufacturing, moving towards a more resilient and diversified supply chain. Without these interventions, the U.S. risks continued and potentially increasing vulnerability to geopolitical shifts and supply disruptions.
Beyond the Headlines
The issue extends beyond immediate supply chain concerns to broader geopolitical and economic implications. The concentration of specialty gas and mineral production in China highlights a fundamental challenge in globalized manufacturing: the trade-off between efficiency and resilience. While economic factors historically favored outsourcing to lower-cost regions, the current situation reveals the strategic risks associated with such dependencies. The report implicitly calls for a re-evaluation of industrial policy, suggesting that national security and economic stability may necessitate interventions that go against purely market-driven decisions. The 'purity and qualification' aspect of specialty gases also points to the intricate and specialized nature of semiconductor manufacturing, where even minor disruptions in highly specific inputs can have cascading effects across the entire industry. This situation underscores the need for a holistic approach to supply chain security, considering not just the final product but every critical component and raw material.
