China's Push for Domestic Silicon Wafers: Q&A on the 2026 Target
China is accelerating its drive for semiconductor self-sufficiency by setting an ambitious target: by 2026, over 70% of silicon wafers used by its chipmakers must be produced domestically. This goal comes with an unspoken mandate for manufacturers to prioritize local 12-inch wafers, reshaping supply chains and competitive dynamics. Below are key questions and answers exploring the implications of this policy.
What is China’s target for domestic silicon wafer usage?
According to sources cited by Nikkei Asia, China aims for more than 70% of silicon wafers used by its chipmakers to be produced domestically by 2026. This target applies specifically to 12-inch (300mm) wafers, which are the industry standard for advanced semiconductor manufacturing. The directive is part of a broader strategy to reduce reliance on imports from countries like Japan, South Korea, and the United States. Currently, domestic production meets only a fraction of demand, but the new goal signals a determined push toward self-reliance amid ongoing technology restrictions and geopolitical tensions.
Why is China focusing on silicon wafers?
Silicon wafers are the fundamental substrate for nearly all chips, making them a critical component in the semiconductor supply chain. China’s focus stems from several factors: first, national security concerns – reliance on foreign wafers exposes domestic chipmakers to supply disruptions and export controls. Second, cost and scale – the country already invests heavily in chip fabrication, so controlling upstream materials can lower costs and improve integration. Third, technological sovereignty – mastering wafer production (especially 12-inch, used for nodes below 28nm) is seen as essential for advancing domestic chip manufacturing capabilities, especially for AI and high-performance computing.
What does the “unspoken mandate” for local 12-inch wafers mean?
While no formal decree has been published, chipmakers in China perceive a strong, unstated requirement to source 12-inch silicon wafers from domestic producers. This “unspoken mandate” is conveyed through government guidance, industrial policy signals, and informal expectations during meetings. Companies that fail to comply may face difficulties in obtaining permits, subsidies, or favorable treatment. The mandate effectively pressures fab operators—both local giants like SMIC and foreign-owned factories in China—to shift procurement from established foreign suppliers (such as Shin-Etsu, Sumco, and GlobalWafers) to emerging Chinese players like Zhonghuan Semiconductor and NSIG. The goal is to create a guaranteed domestic demand that accelerates local capacity expansion.
How does the 2026 target compare to current domestic production?
As of 2024, China’s domestic production of 12-inch silicon wafers meets less than 20% of its chipmakers’ demand. The vast majority of wafers are imported, primarily from Japan and Taiwan. To reach the 70%+ target by 2026, the country needs to more than triple its domestic output within three years. This requires massive investments in new wafer fabs, technology upgrades, and supply chain infrastructure. Key domestic players are racing to expand capacity—for example, Zhonghuan Semiconductor has announced plans to build a new 12-inch wafer factory with monthly capacity of 600,000 pieces. Even with these efforts, analysts question whether the timeline is achievable given the complexity of wafer manufacturing and the need to certify products with leading-edge chip fabs.
What challenges does China face in achieving this goal?
Several hurdles stand in the way. Technical challenges include mastering high-purity silicon crystal growth, defect-free polishing, and precise doping for advanced 12-inch wafers—a process dominated by Japanese and German firms for decades. Equipment and materials for wafer production are also subject to export controls; China must develop its own furnaces, slicers, and chemicals. Qualification cycles are lengthy: a new wafer supplier must pass rigorous testing by chip fabs, which can take 12–24 months. Market dynamics add friction: foreign wafer suppliers hold long-term contracts with Chinese fabs, and unilaterally shifting to local producers risks quality issues and supply instability. Finally, the goal may face pushback from chipmakers who worry about performance trade-offs or higher costs of domestic wafers.
How might this affect global semiconductor supply chains?
If China succeeds, the global wafer market—worth over $14 billion—will see a major rebalancing. Established suppliers like Shin-Etsu, Sumco, and GlobalWafers could lose a significant portion of their Chinese revenue, forcing them to seek alternatives elsewhere. Conversely, Chinese wafer producers will gain market share, potentially leading to lower global wafer prices due to oversupply in the near term. However, the push may also accelerate technology decoupling: foreign chip fabs in China (e.g., those owned by Samsung, SK Hynix, or TSMC) might be compelled to use domestic wafers, complicating their global quality standards. Long-term, the move could fragment supply chains into two blocs—one centered on China, the other on the rest of the world—raising geopolitical tensions.
Which companies are most impacted?
The policy directly affects three groups. Chinese chipmakers (e.g., SMIC, Hua Hong, YMTC) must adjust procurement strategies and qualify new domestic wafer suppliers. Foreign wafer producers with sales to China (Shin-Etsu, Sumco, GlobalWafers, Siltronic) face potential revenue drops of 30–50% in that market. Domestic wafer manufacturers (Zhonghuan Semiconductor, NSIG, Hangzhou Lion Micro) will see a surge in demand but must ramp up quality and capacity. Also impacted are equipment makers (e.g., for crystal pullers) that supply these new fabs, and materials suppliers—especially those producing polycrystalline silicon, crucibles, and polishing pads. Over time, even downstream electronics brands that source chips from China may feel price or availability effects.
