Packaging Bottleneck Rises
- AI demand is shifting chip scarcity from fabrication to advanced packaging, creating a new supply constraint. - Analysts say AI could soon account for roughly a third of TSMC’s business. - That makes throughput depend more on packaging capacity and cross‑site integration across the supply chain (nextplatform.com).
The chip shortage in artificial intelligence is moving to the back end: packaging, not fabrication, is emerging as the harder step to scale. (nextplatform.com) Taiwan Semiconductor Manufacturing Co. reported $35.9 billion in first-quarter 2026 revenue on April 16 and guided second-quarter revenue to $39.0 billion to $40.2 billion. Gross margin was 66.2% in the quarter. (investor.tsmc.com) TSMC said advanced chips made on 7-nanometer processes and below accounted for about 75% of wafer revenue in the quarter, a sign that demand remains concentrated in the most complex products used for AI systems. CNBC reported the company posted a 58% profit increase. (cnbc.com) Packaging is the step that turns separate pieces of silicon into a finished processor, linking logic chips and high-bandwidth memory in one module. For AI accelerators, that assembly work often uses TSMC’s CoWoS technology, short for chip-on-wafer-on-substrate. (cnbc.com) CNBC reported on April 8 that Nvidia had reserved most of TSMC’s most advanced packaging capacity. DigiTimes reported on April 10 that global advanced-packaging capacity remains in severe shortage and that CoWoS output has become a bottleneck for AI hardware shipments. (cnbc.com) (digitimes.com) The Next Platform estimated on April 20 that AI-related demand could soon represent roughly one-third of TSMC’s business. That calculation leans on TSMC’s high-performance computing category, which includes graphics processors, custom accelerators, networking chips and field-programmable gate arrays, not just AI chips. (nextplatform.com) That mix changes where delays show up. A chip can clear the front-end manufacturing line and still wait for packaging slots, memory stacks, substrates, testing and transport before it becomes a server-ready part. (cnbc.com) (nextplatform.com) TSMC has been expanding that back-end capacity while broadening its global footprint. Its 2025 annual report, filed April 16, said the company manufactured 12,682 products for 534 customers in 2025 and highlighted advanced packaging alongside leading-edge and specialty technologies. (investor.tsmc.com) The constraint is no longer only how many wafers TSMC can print each quarter. It is how many AI chips the supply chain can finish, package and move as one synchronized system.
