Frequently Asked Questions

What is current semiconductor fab utilization?
TSMC fab utilization recovered to approximately 90% by Q1 2025, up from the cyclical trough of roughly 70% in Q2 2023. Advanced nodes (3nm, 5nm) run at near-100% utilization while mature nodes (28nm+) remain around 60–70%.
Why did fab utilization drop in 2023?
The 2023 utilization downturn was caused by post-COVID inventory correction in consumer electronics (PCs, smartphones), coinciding with the DRAM/NAND price crash. AI demand partially offset this at leading-edge nodes, but mature nodes saw severe underutilization.
