TSMC

TSMC (Taiwan Semiconductor Manufacturing Company) is the world's dominant dedicated semiconductor foundry, holding an estimated 80–90% share of the most advanced semiconductor manufacturing market as of mid-2025, per a Yunqi Capital analysis of Mary Meeker's AI trends report . The company's scale and process leadership have made it a central node in the U.S.-China technology competition: Washington has used export controls and the CHIPS Act to push for domestic chip manufacturing, while TSMC itself committed $65 billion to build factories in Arizona—described by FreeS Research as the largest foreign direct investment in U.S. history—though the project faced significant delays, with production still not fully operational four years after its 2020 announcement .

In the AI era, TSMC's role has only grown more critical. Its CEO wrote in IEEE Fellow that GPU transistor counts could reach 1 trillion within a decade, driven by advanced packaging and interconnect technologies—a shift 5Y Capital's Kai Liu cited as evidence that "Huang's Law" has supplanted Moore's Law in setting the pace of semiconductor progress . The company's manufacturing decisions ripple across the global supply chain: when U.S. restrictions tightened on advanced chips, Chinese imports of integrated circuits dropped 26.5% year-on-year in early 2023 as TSMC and other leading foundries navigated export control pressures . TSMC's capacity allocation also reflects broader industry shifts—Horizon Robotics' Kai Yu noted that TSMC directs its largest production volumes toward whichever智能终端 dominates each era, from PC chips to smartphone processors .
