Exclusive: TSMC SoIC deepens AI chipmaker lock-in while Huawei hits process wall - digitimes

The global semiconductor industry stands at a critical inflection point, divided between those who can still shrink transistors and those who cannot. US export controls and the denial of EUV lithograp... Read original →

U.S. export controls on EUV tools have erected a de facto 'technological Berlin Wall,' halting Chinese foundries at the 3nm node. TSMC (Taiwan, China) leverages SoIC and advanced packaging not only to offset Moore's Law deceleration but to lock AI chipmakers like NVIDIA into its manufacturing ecosystem. This 'front-end blockade, back-end breakthrough' dynamic pushes Chinese firms toward chiplet-based designs, yet they lack the interconnect density and yield control for competitive performance. Huawei’s architectural prowess is nullified without access to leading-edge fabrication. Over the next 12–24 months, the AI chip supply chain will bifurcate: one track led by TSMC’s high-end coalition, the other a localized but lagging Chinese alternative. Technological sovereignty is no longer strategic—it’s existential.
