Chinese AI semiconductor companies face production constraints amidst ongoing US export controls. To circumvent these limitations, companies have adjusted their chip designs to meet requirements that do not trigger American sanctions, subsequently outsourcing production to foreign foundries like Taiwan Semiconductor Manufacturing Company (TSMC).
Despite these efforts, there is growing concern over China’s potential dominance in the legacy semiconductor market, which could tighten the global supply chain. TSMC, which uses US equipment and therefore is subject to the same restrictions, has received downgraded semiconductor designs from leading AI firms in China such as MetaX and Enflame.
MetaX, founded by former AMD executives in 2020, and Enflame, backed by IT giant Tencent, have traditionally compared their chips to Nvidia’s GPUs and have sold to both government and commercial companies in China. However, due to the scarcity of foundries capable of high-end GPU production within China, they have turned to TSMC for manufacturing assistance.
For China, this pivot to TSMC was necessary as domestic chip production capabilities are limited. Among China’s approximately 44 foundries, only SMIC had the capacity to produce advanced GPUs, but its resources are fully allocated to Huawei, leaving other AI semiconductor startups at a standstill.
Ironically, while struggling to produce cutting-edge chips, China may gain influence in the legacy semiconductor arena. Legacy chips remain in high demand for a variety of technology applications, including self-driving vehicles and smartphones, signifying a potential risk to the global supply chain if China monopolizes this market.
Nevertheless, global entities such as TSMC are not yielding control of the legacy semiconductor market. TSMC’s affiliate, Vanguard International Semiconductor Corporation (VIS), and Dutch semiconductor firm NXP have announced a joint venture to construct a $7.8 billion semiconductor wafer manufacturing plant in Singapore, focusing on producing wafers for legacy semiconductor fabrication.
Key Challenges and Controversies
– Technological Competition: A key challenge for China’s AI semiconductor firms is keeping up with the technological advances while navigating US export controls. These controls can hinder their ability to obtain leading-edge semiconductor manufacturing equipment and design tools, which are necessary for developing high-end chips.
– Dependence on Foreign Production: Chinese firms’ dependence on foreign foundries like TSMC to produce their chips makes them vulnerable to international geopolitical dynamics and changes in trade policies.
– Supply Chain Security: There is a potential risk to global supply chain security if China dominates the legacy semiconductor market since it can impact the availability and price of these crucial components for numerous industries worldwide.
– IP and Security Concerns: There are controversies surrounding the intellectual property rights, as well as security concerns, over potential backdoors in chips that could be used for espionage or cyberwarfare by state actors.
Advantages and Disadvantages
– Advantages: For China, becoming a dominant player in the legacy semiconductor market could foster economic growth and lead to greater self-sufficiency in this critical technology sector.
– Disadvantages: The major disadvantage of the current situation is the potential stagnation of China’s progress in advanced semiconductor technology due to export controls, limiting the global technological advancement pace and possibly causing a technology decoupling between China and the US.
