Taiwan Semiconductor Manufacturing Company (TSMC)

Taiwan Semiconductor Manufacturing Company, founded in 1987 by Morris Chang, is the world's largest dedicated semiconductor foundry and the exclusive manufacturer of essentially all leading-edge AI chips. TSMC pioneered the pure-play foundry model—fabricating chips designed by others rather than designing its own—and through decades of execution excellence achieved technological leadership at the smallest process nodes. As of 2025-2026, TSMC manufactures all NVIDIA H100 and successor GPUs, all Apple M-series and A-series processors, and the majority of advanced logic chips for AMD, Qualcomm, and other fabless designers. The company's technological edge rests on three pillars: superior process expertise (achieving higher yields and better performance than competitors at equivalent node sizes), capital investment discipline (spending $30-40 billion annually on fab construction and equipment), and workforce excellence (tens of thousands of experienced engineers whose tacit knowledge is not easily replicated). TSMC's concentration in Taiwan—roughly 90% of leading-edge capacity—creates the semiconductor supply chain's most significant geopolitical vulnerability.
