Chinese AI Chip Startup Leverages 3D Stacking to Navigate US Export Controls
A Chinese AI chip startup has exited stealth mode with a focus on 3D stacking technology as a potential workaround to US export controls on advanced semiconductors.
The company is betting that 3D stacking—which involves vertically layering chip components—could allow it to achieve high-performance AI computing capabilities while potentially using components that fall outside current restricted categories. This approach represents one of several strategies Chinese firms are exploring to develop competitive AI hardware amid tightening US export restrictions on advanced chips and chipmaking equipment.
3D stacking technology enables manufacturers to increase chip density and performance by vertically integrating multiple chip layers, potentially achieving efficiency gains without relying on the most advanced single-layer fabrication processes that are subject to export controls.
The emergence of this startup reflects the broader push by Chinese companies to build self-sufficient semiconductor capabilities in response to US restrictions that have limited access to cutting-edge chips and the equipment needed to produce them.
