TSMC targets 50x computing boost by 2029 with advanced packaging

TSMC Taiwan Semiconductor Manufacturing Company Limited ↗ 6.33% outlined an aggressive technology roadmap on Monday at SEMICON Taiwan 2026, projecting that its SoIC and CoWoS advanced packaging technologies will deliver a 50-fold increase in system computing performance over 2024 levels by 2029, as the chipmaker positions itself at the center of what it calls the "true industrialization of AI."

Integrated Systems Over Individual Chips

April Li, TSMC's global head of AI and high-performance computing business development, said in a keynote at the event's IC Forum that AI computing demand is growing fivefold annually, creating mounting pressure across the semiconductor supply chain. Rather than relying on advances in individual chips or models, she argued, future AI infrastructure must integrate computing, memory, interconnects, storage, and power management across chips, server racks, and entire data centers.trendforce+1

"In this new era, market leaders will not be the ones who simply make better models, but those who build the most integrated systems," Li said.focustaiwan

Li pointed to soaring inference demand as a key driver, noting that global inference token volume has increased nearly 500-fold since 2022, while agentic AI systems consume far more tokens than conventional queries. Data movement alone can account for up to 60 percent of system activity in typical workloads, she said, leaving expensive accelerators operating at below 40 percent utilization.focustaiwan

Packaging Roadmap and Silicon Photonics Push

To meet these demands, TSMC is advancing its 3DFabric platform, which combines SoIC 3D stacking and CoWoS advanced packaging. The company plans N2P-on-N3P 3D integration in 2026, followed by A14-on-A14 in 2029, with interconnect pitch shrinking to 4.5 microns. TSMC is already mass-producing CoWoS at 5.5-reticle size, with a 14-reticle package fitting roughly 10 compute dies and 20 HBM stacks planned for 2028.xenospectrum+2

Separately, TSMC Vice President K.C. Hsu said silicon photonics is expected to account for more than 50 percent of the optical transceiver market by 2027, with some suppliers set to begin mass production of co-packaged optics in the second half of 2026. TSMC's COUPE platform integrates electronic and photonic circuits, targeting bandwidth scaling from 3.2 Tbps to more than 12.8 Tbps.trendforce

CoWoS Capacity Still a Bottleneck

Despite a roughly ninefold expansion in CoWoS capacity over three years — from around 13,000–16,000 units per month at the end of 2023 to a projected 120,000–140,000 by the end of 2026 — a supply-demand gap of approximately 10 percent is expected to persist. Nvidia ↗ 2.78% alone is estimated to control 60 percent of global CoWoS demand, leaving AMD Advanced Micro Devices, Inc. ↗ 11.04%, Broadcom ↗ 0.74%, and cloud providers to compete for the remainder.xenospectrum

"Gone are the days when we can just ship wafers across the fence," Li said, describing how TSMC's role now extends from silicon to the data center.focustaiwan
