TSMC controls over 90% of advanced sub-7nm chip manufacturing. A deep dive into its $70.6 billion revenue engine, Arizona fab construction, Morris Chang's foundry model, and the geopolitical risk that places global tech infrastructure directly in the Taiwan Strait.

TSMC captures over 60% of global contract semiconductor fabrication and over 90% of advanced sub-7nm production. It manufactures chips for Apple, Nvidia, AMD, and Qualcomm — companies that collectively define the digital economy.
FY2023: Revenue $70.60B, gross margin 54.4%, operating margin 42.6%, net income $26.88B, CapEx $32.45B. Advanced nodes (7nm and below) = 59% of wafer revenue. 3nm alone reached 15% of revenue within quarters of commercial launch.
Founded 1987 in Hsinchu, Taiwan, by Morris Chang (Texas Instruments veteran, Stanford Ph.D.). Revolutionary thesis: be a pure-play foundry that never competes with customers. This enabled the fabless revolution — Nvidia, Broadcom, Qualcomm could focus entirely on chip design, leaving manufacturing to TSMC. TSMC achieved superior yields through higher fab utilization across hundreds of clients.
Committed $65B+ for three Phoenix fabs: Fab 1 (4/5nm), Fab 2 (3nm), Fab 3 (2nm). Structural headwinds: US fab costs 4-5x more than Taiwan (permits, wages, supply chain fragmentation), labor shortages, management friction. And TSMC maintains a policy of keeping absolute leading-edge nodes in Taiwan.
Most advanced capacity is in western Taiwan. A Chinese blockade or invasion would halt the global supply of advanced chips within months. No alternative manufacturer can replicate TSMC's yields at sub-7nm. This is why the US CHIPS Act ($52.7B) was passed — but Arizona fabs are years from parity. See ASML.
