Semiconductors

Semiconductors are crucial to many of China’s strategic goals: digitalizing the economy, boosting high-tech exports such as electric vehicles (EVs) and solar panels, and developing modern weapons. With its state-led “Big Fund,” China has invested more than CNY 686 billion (EUR 87.5 billion) into the industry since 2014, in addition to local government support and private investment. 

Indigenizing the semiconductor industry has gained urgency, as US sanctions and export controls have cut off access to advanced semiconductors critical for development in AI, military and other fields. 

Since the US sanctioned the telecoms giant Huawei in 2019, Huawei has quietly become the central force in the state’s effort to develop homegrown chips, alongside other companies. China is a major producer of semiconductors using older manufacturing technology and is a leader in backend processes – chip assembling, testing, and packaging. But it lags in making advanced semiconductors and lacks the tools to manufacture them. US export controls have cut off access to critical foreign-made equipment.

Nevertheless, leading manufacturer SMIC has produced an advanced 7nm smartphone chip and a line of AI chips, both for Huawei. Taiwan’s TSMC, the world’s leading semiconductor contract manufacturer, first pioneered a 7nm process in 2018 (has since produced several rounds of further innovations), suggesting SMIC lags by roughly five years. However, China’s lack of access to Extreme Ultraviolet Lithography (EUV) machines, essential for making advanced semiconductors and exclusively produced by the Netherlands’ ASML, may hamper further progress.

In push for self-reliance, Chinese chipmakers up R&D investments
In push for self-reliance, Chinese chipmakers up R&D investments

Chinese chipmakers are actively increasing their R&D expenditure. This is driven by the AI boom, rising demand for computing power, and China’s drive for self-sufficiency in advanced semiconductors. The chips are critical for artificial intelligence (AI) infrastructure, where the country lags behind foreign rivals. China’s leading chipmakers are investing a growing share of their revenue in R&D, on par with global leaders. However, their total investment remains lower in absolute terms. Subsidies by the Chinese government may also inflate their ability to invest in R&D.

China’s footprint in memory chips grows slowly

China gains ground in DRAM global market, competing with Samsung, SK hynix, and Micron. Its share of the global memory chip market has climbed from 0.6 percent to 5 percent in just four years, driven largely by ChangXin Memory Technologies (CXMT), now the world’s fourth-largest DRAM maker by capacity. CXMT mainly produces mature products like DDR4 and LPDDR4 chips but is signaling ambition toward DDR5 and HBM which are important for AI chips. In the last two years, CXMT has expanded to three 12-inch wafer fabs in Beijing and Hefei and is planning new plants in Shanghai with two to three times the Hefei capacity. CXMT’s gain in the memory market is a milestone for China in challenging the dominance of South Korean and US memory chip makers, but it still has a long way to go to compete at scale.

Producing advanced semiconductors: A highly complex process with many dependencies

China faces the daunting task of trying to own the entire manufacturing process for semiconductors, which is highly complex with many steps. This is even more so with advanced semiconductors, which requires specialized equipment from other countries.

Recent developments
  • Huawei announced a new „breakthrough” in vertically stacking semiconductors to increase transistor density without the most advanced machinery. The so-called Tau Scaling law is supposed to allow Huawei to produce 1.4nm-class chips by 2031, although experts point to many problems that need to be conquered and the low yield of Huawei’s current AI chips as hurdles. For reference, TSMC is planning to mass-produce 1.4nm-class chips in 2028 (Source (CN): Huawei, May 25, 2026)
  • China’s second-largest chipmaker, Hua Hong Group, is preparing to produce 7nm chips to strengthen the self-sufficiency of China’s AI stack. The company hopes to join China’s number one chipmaker Semiconductor Manufacturing International Corporation (SMIC), currently the only domestic company able to produce AI accelerator chips. (Source (EN): Reuters, March 16, 2026)
  • The US has ordered multiple chip equipment companies to halt shipment of tools to Hua Hong, China's second-largest chipmaker, after the company announced it had produced 7nm AI chips. (Source (EN): Reuters, April 28, 2026)
  • China's largest LED chipmaker, Sanan Optoelectronics, has abandoned its USD 239-million bid to acquire Dutch lighting firm Lumileds after the US Committee on Foreign Investment (CFIUS) ruled that the deal posed a major national security risk. This is the second time the US has blocked an acquisition of the company by a Chinese player. (Source (EN): SCMP, April 17, 2026)
  • Nexperia China announced domestic small-batch production of 12-inch wafers for bipolar discretes, key semiconductors for autonomous driving based on a self-developed platform, after supply disruptions in October last year due to the Dutch court case on Nexperia. (Source (CN): EET, March 16, 2026)
  • Wingtech Technology, Chinese owner of chipmaker Nexperia, is at risk of being delisted from the Shanghai Stock Exchange after failing an audit because it could no longer access Nexperia's overseas business and financial data. The company's shares and bonds were already suspended for one day on April 30 following a sell-off and are set to be terminated if the dispute isn't solved this year.

Huawei: From telecommunications provider to technology manufacturing leader

Huawei has emerged as the leader for semiconductors  in China.  It designed the first domestically-produced 5G-capable smartphone chip, the Kirin 9000S and is invested in 97 companies through its Hubble Investment arm. In the global technology competition between China and the US, Huawei thus now plays a key role in two of the most critical technologies, mobile internet and semiconductors.
