TSMC Approves Record $45B Budget for AI Chip Capacity

Why it matters

- A significant portion of the budget is expected to fund the expansion of TSMC's advanced packaging capacity, particularly for its Chip-on-Wafer-on-Substrate (CoWoS) technology. Demand for CoWoS is surging from major clients like NVIDIA, AMD, Google, and Amazon for their AI and HPC chips. TSMC projects its CoWoS capacity will see a compound annual growth rate of over 50% from 2022 to 2026. - This investment will bolster production of TSMC's next-generation 2-nanometer and 3-nanometer nodes. Major tech companies, including Apple, NVIDIA, AMD, and MediaTek, are reportedly the first customers lined up for the 2nm process, which is seeing higher demand than the 3nm node at a similar stage. - The build-out supports the production of upcoming high-performance chips like NVIDIA's Blackwell B200 GPU, which is built on TSMC's 4nm process and has demand that already exceeds supply. TSMC is also in talks with NVIDIA to potentially produce some Blackwell GPUs at its new fab in Arizona, though advanced packaging would still need to be done in Taiwan. - This capital expenditure aims to maintain TSMC's lead over competitors Samsung and Intel. While Intel's forthcoming 18A process may offer competitive performance, TSMC is expected to maintain an edge in transistor density and manufacturing yields. Meanwhile, some of Samsung Foundry's AI chip customers have reportedly been moving to TSMC for their next-generation products. - The investment addresses the broader "build vs. buy" dilemma faced by hyperscalers like Amazon, Microsoft, and Google. These companies are increasingly designing their own custom AI ASICs (like Google's TPU and Amazon's Trainium) to optimize for specific workloads and reduce reliance on third-party chips, with ASIC shipments projected to triple between 2024 and 2027. - A portion of the funds will be allocated to TSMC's new fabrication plants, including its facilities in Arizona. This global diversification strategy helps mitigate geopolitical risks and secures supply chains for key customers in the United States.
