TSMC is the world’s largest dedicated semiconductor foundry, providing advanced logic, specialty technologies, advanced packaging, testing, and design support to fabless chip designers, IDMs, and system companies. It is central to leading process nodes such as 3nm, 5nm, and 7nm, the N2 roadmap, and CoWoS advanced packaging used in AI accelerators, mobile processors, high-performance computing, and automotive chips. TSMC is expanding capacity in Taiwan, the United States, Japan, and Europe to meet AI and advanced-node demand, while key risks include geopolitics, energy availability, export controls, and customer concentration.
