Chinese AI chip start-up Dongfang Suanxin has exited stealth mode, launching a focus on 3D stacking technology as a strategy to circumvent U.S. export controls. These controls, reaffirmed by the U.S. Department of Commerce in June, require licensing for advanced AI chip exports to companies based in China and their foreign subsidiaries. This move aligns with a broader trend among major Chinese tech firms like Huawei, which are also adopting 3D stacking and advanced packaging methods to enhance AI chip performance while avoiding reliance on restricted semiconductor manufacturing resources.

Dongfang Suanxin: Dongfang Suanxin is a Shanghai-based Chinese AI chip startup led by industry veteran Wei Shaojun, who also serves as vice-president of the China Semiconductor Industry Association. The company recently exited stealth mode by launching its official website and social media accounts, positioning itself as a player in China’s AI computing sector. It develops high-performance AI accelerators using technologies such as 3D stacked near-memory computing and software-defined chips to address domestic needs amid international trade restrictions.

Export Controls: The United States Department of Commerce issued guidance in June affirming that licensing requirements for advanced AI chip exports apply to businesses with headquarters or parent companies in China, including their overseas subsidiaries.
Industry Approach: Major Chinese technology firms such as Huawei are pursuing 3D stacking and advanced packaging methods to improve AI chip capabilities without depending on restricted semiconductor manufacturing equipment or processes.
