TSMC Uses AI to Build 1.4nm A14 Chip Plants

TSMC is investing $49 billion into four plants dedicated to its 1.4nm process node, officially designated as A14. To meet a mid-2028 production target, the company is deploying AI tools to analyze heavy equipment maneuvers, structural assembly, and cleanroom infrastructure in real time. These AI systems also manage heat hazards generated by EUV machines during trial runs. High-temperature sensors monitor thermal and humidity levels, while an AI thermal management system regulates liquid-cooling channels to prevent thermal expansion from distorting sensitive 1.4nm wafers. Reports suggest each A14 wafer could cost $45,000. Apple is expected to utilize this technology for its A22 Pro chip in the 2028 iPhone lineup.
