Huawei Reportedly Used AMAT and LAM Tools to make 7 nm Chip in 2023

Before the U.S ban in October 2022, SMIC already had access to the American technology required for chip production.


China’s semiconductor ambitions stand as a testament to its aspirations for technological self-sufficiency and global competitiveness. At the forefront of this endeavor lies Huawei’s chip. The Chinese company, Semiconductor Manufacturing International Corporation (SMIC), was able to produce a 7nm chip for Huawei, a major milestone for domestic chip production in China.

Despite restrictions, SMIC reportedly used equipment from US companies Applied Materials and Lam Research to manufacture the chip. This raises questions about the effectiveness of the sanctions.

Huawei, a Chinese tech giant previously reliant on TSMC (Taiwan) for advanced chips, was able to secure a domestically produced alternative thanks to SMIC.

In this exploration, we delve into Huawei’s chip endeavors to unravel the multifaceted landscape of China’s semiconductor ambitions, offering insights into the forces shaping its pursuit of self-reliance in the crucial domain of semiconductor technology.

The Role of Foreign Technology in Huawei Chip

Despite China’s efforts to achieve technological self-sufficiency, the revelation that US technology played a crucial role in this chip production highlights the continued dependence of Chinese firms on foreign components and equipment.

While China has made strides in enhancing its domestic chip design and manufacturing capabilities, certain critical technologies remain sourced from abroad.

Before the U.S. Department of Commerce implemented restrictions in October 2022, sources informed Bloomberg that SMIC already had access to the American technology required for chip production. Subsequently, in November 2022, the U.S. further prohibited the approval of equipment from Huawei and other Chinese firms, citing concerns over national security risks.

While SMIC achieved a 7nm process, there are reports that the chip’s performance might not match those from leading manufacturers like TSMC. US officials believe SMIC might not be able to produce these chips in large enough quantities.

Geopolitical Implications and Trade Restrictions

MIC producing a 7nm chip for Huawei have multifaceted implications, impacting China, the US, and the global tech landscape. Here’s a breakdown of some key areas:

For China:

  • Technological advancement: This demonstrates progress in China’s domestic chip manufacturing, reducing reliance on foreign suppliers like TSMC. It could spur further investment and development in the Chinese semiconductor industry.
  • Geopolitical leverage: China’s chip independence strengthens its position in the ongoing tech war with the US. It lessens the impact of US sanctions on Huawei.

The US:

  • Efficacy of sanctions: The use of US equipment by SMIC raises questions about the effectiveness of US export controls on China’s chip sector. The US might tighten restrictions in response.
  • Geopolitical competition: China’s progress could accelerate the US effort to maintain its lead in chip technology. This could potentially restrict access to advanced technology for China.

For the global tech industry:

  • Supply chain diversification: This could lead to a more diversified global chip supply chain, potentially reducing dependence on a few major players.
  • Technological competition: Increased competition between the US and China could accelerate innovation in chip technology, benefiting the industry as a whole.

However, there are also some uncertainties:

  • Performance: SMIC’s 7nm chips might not match the performance of those from leading manufacturers.
  • Production capacity: SMIC might not be able to produce these chips in large enough quantities to meet Huawei’s full demand.

Overall, the implications are significant and will continue to unfold. It’s a story of technological advancement, geopolitical competition, and its impact on the global chip industry.
