1. Summary

  • The report explores China's strategic push to enhance its high-bandwidth memory (HBM) production capabilities. Key players like Huawei Technologies have been central to this effort, working under the umbrella of significant government support despite facing obstacles from US trade restrictions. Huawei's collaboration with domestic companies such as Fujian Jinhua Integrated Circuit highlights the collective initiative toward achieving semiconductor independence. Presently, the global HBM market is dominated by South Korean companies SK Hynix and Samsung Electronics. Although Chinese firms aspire to enter the market, they encounter technological barriers that challenge their progress. The report also examines the shifting landscape, recognizing the potential for future competitive dynamics if China achieves its production goals.

2. Background and Importance of HBM Technology

  • 2-1. Definition and use of High-Bandwidth Memory

  • High-Bandwidth Memory (HBM) is a type of memory used in computing systems that allows for the efficient processing of large amounts of data, particularly in applications related to artificial intelligence (AI). HBM is crucial for performance in high-demand sectors such as graphics processing, machine learning, and data centers. Companies like Huawei have been using HBM2E chips from Samsung to enhance the capabilities of their Ascend AI chips. This highlights the growing relevance of HBM technology in enabling advanced computing solutions.

  • 2-2. Global leaders in HBM production and market share

  • Currently, the global market for HBM is dominated by South Korean companies, with SK Hynix and Samsung holding approximately 47.5% of the market share each in 2023. Micron Technology holds a smaller share of roughly 5%. Reports indicate that the competitive landscape is somewhat shifting, with SK Hynix's market share expected to increase to 52.5% in 2024 while Samsung's might decrease to about 42.4%. While Chinese firms, including Huawei, are beginning efforts to enter the HBM space, they face significant challenges due to existing technological restrictions and established competition.

3. China's Strategic Push towards HBM Self-Sufficiency

  • 3-1. Huawei's role and strategic initiatives in HBM production

  • Huawei is actively establishing high-bandwidth memory (HBM) production lines and plans to initiate domestic production by 2026. The company's involvement is intensified by its collaboration with YMTC's subsidiary and other domestic semiconductor firms. Despite facing challenges from US regulations, Huawei's commitment to entering the HBM market indicates its determination to capitalize on the domestic demand for AI chips. Furthermore, the success of Huawei’s Ascend AI chips highlights the potential growth of its domestic HBM capabilities, despite current supply issues.

  • 3-2. Government support and policy measures

  • The Chinese government has significantly ramped up efforts to bolster domestic semiconductor production amidst strict trade restrictions imposed by the US. This support includes funding and collaborative initiatives aimed at producing high-bandwidth memory chips, which are essential for graphic processing units. The government's backing for the consortium led by Huawei demonstrates its strategic vision to achieve self-sufficiency in the semiconductor sector by 2026, although experts express skepticism regarding the ability of Chinese firms to bridge the technological gap with established players such as SK hynix and Samsung.

  • 3-3. Collaborative efforts among Chinese firms

  • Collaboration among Chinese semiconductor firms is critical for advancing the nation’s HBM production capabilities. Companies like Huawei, Fujian Jinhua Integrated Circuit, and CXMT are working together in what is being referred to as a 'Team China' approach. This partnership strategy facilitates the design and manufacturing of HBM chips, which is increasingly seen as a tangible path toward semiconductor independence. The cooperation also positions these firms to challenge the dominance of South Korean companies in the HBM market.

4. Challenges and Limitations

  • 4-1. Impact of US trade restrictions on China’s semiconductor industry

  • The U.S. is considering new restrictions on the export of high-bandwidth memory (HBM) produced by companies such as SK Hynix and Micron to China. HBM technology is crucial for enhancing data processing capabilities, notably for AI applications. Industry insiders assert that without access to advanced technologies such as GAA and HBM, China is unable to independently produce AI semiconductors. The Biden administration's policies have the potential to restrict South Korean companies like Samsung Electronics and SK Hynix from selling related products to China, amplifying the challenges faced by the Chinese semiconductor sector.

  • 4-2. Technological barriers and competitive landscape

  • China’s semiconductor industry is at a significant disadvantage due to limitations on obtaining advanced manufacturing equipment due to ongoing sanctions. For instance, Zhang Pingan, the CEO of Huawei Cloud, indicated that without access to advanced equipment, producing semiconductors using 3nm and 5nm processes is highly challenging, with achieving mass production on the 7nm process considered a notable success. Additionally, prominent Chinese firms such as Baidu and Huawei are reportedly stockpiling HBM chips from Samsung, fearing further U.S. restrictions. Companies like Huawei are also exploring collaborations to produce HBM2 chips with local partners by 2026, although they face ongoing pressures that threaten their production capabilities.

5. Future Prospects and Market Implications

  • 5-1. Potential market shifts and China’s position in global HBM production

  • The report indicates that China is currently in the early stages of high-bandwidth memory (HBM) development. Despite facing strict technological restrictions from the United States in the semiconductor and artificial intelligence sectors, Huawei's entry into HBM production has garnered significant attention. As of 2023, South Korean companies SK Hynix and Samsung Electronics dominated the global HBM market, with each holding approximately 47.5% market share, while Micron held around 5%. Projections for 2024 suggest that SK Hynix’s market share could increase to 52.5%, whereas Samsung’s may decrease to 42.4%. This competitive landscape underscores the challenges that Huawei and other Chinese firms must overcome to establish a substantial presence in the global HBM market.

  • 5-2. Predicted outcomes if China achieves its HBM goals

  • While the report does not provide specific predictions about outcomes, it suggests that if China successfully advances its HBM production capabilities, significant shifts in the global semiconductor market could occur. Achieving these goals could potentially redefine competitive dynamics within the industry, impacting supply chains and altering market shares among leading manufacturers. However, it is important to recognize that substantial technical barriers and ongoing trade tensions with the U.S. may impede these aspirations.

6. Conclusion

  • The report underscores the intense focus of China, led by major entities such as Huawei Technologies, on advancing high-bandwidth memory (HBM) production. Their efforts are a part of a broader strategy to reduce reliance on foreign technology and achieve semiconductor self-sufficiency. Despite the strategic collaboration involving companies like Fujian Jinhua Integrated Circuit, substantial hurdles persist, primarily due to the dominance of SK Hynix and Samsung Electronics in the HBM market and US-imposed technological restrictions. The Chinese government's backing indicates a long-term commitment, which, if successful, could shift competitive dynamics and influence global supply chains. However, achieving technological parity remains a daunting task, exacerbated by ongoing international tensions. Future progress in China's HBM sector may open new market opportunities but necessitates navigating complex geopolitical landscapes and advancing technological innovations to compete effectively on a global scale. The practical applicability of these developments extends into various AI applications and high-performance computing sectors, underscoring the strategic importance of these initiatives.
