Who are TSMC's decision-makers?

Dr. C.C. Wei is the apex decision-maker at TSMC, serving as both Chairman and CEO — a dual role he assumed fully in June 2024 following Mark Liu's retirement from the chairmanship. Wei joined TSMC in 1998 and has spent his career advancing process technology; under his CEO tenure (2018–present) revenue has grown from ~US$34B to US$122B and market capitalization peaked above US$2 trillion. His academic background is in electrical engineering (PhD, Yale), and he is widely credited with steering TSMC's aggressive expansion into AI-era nodes and advanced packaging.

Morris Chang, the founder who retired in 2018 at age 86, remains the intellectual architect of TSMC's strategy. Chang spent 25 years at Texas Instruments before persuading the Taiwan government that a dedicated foundry — one that manufactured for others and competed with no one — was viable. His 1987 bet created an entirely new industry structure that today represents approximately 70% of global foundry capacity at the leading edge. The two Co-COOs (Y.P. Chyn and Dr. Y.J. Mii) jointly manage TSMC's 11+ global fabs, splitting manufacturing operations and technology development responsibilities respectively, with Dr. Kevin Zhang leading global customer relationships and Dr. Cliff Hou overseeing cybersecurity as CISO and Deputy Co-COO.

TSMC's procurement structure reflects its engineering culture: technology roadmap decisions (EDA tools, process equipment, IP licensing) are made by process engineering and technology development executives reporting to the Co-COOs. IT and enterprise software purchases — SAP S/4HANA, HR systems, analytics platforms — are owned by IT leadership and the operations finance function, with budget authority typically sitting at the VP or Director level within the relevant business unit.

For new vendors, the path into TSMC typically runs through: (1) the relevant business-unit VP or Director for functional software; (2) central IT / CIO office for infrastructure and enterprise applications; (3) procurement / supply-chain leadership for materials and services. Regional CEOs have budget authority over regional operations including staffing, facilities, and vendor contracts for their geographies — David Keller for North America (Phoenix), Paul de Bot for Europe (Dresden / Munich), and Makoto Onodera for Japan (Kumamoto / Tokyo).

TSMC operates a functional org structure dominated by technology and manufacturing operations, with geographic overlays for its expanding international footprint. The three regions — TSMC North America (Phoenix HQ), TSMC Europe (Dresden/Munich), and TSMC Japan (Kumamoto) — each have dedicated regional presidents with responsibility for their fab campuses and customer service operations. The Japan subsidiary JASM (a joint venture with Sony and Denso) posted its first quarterly profit in Q1 2026, reflecting the Kumamoto fab's successful ramp to high-volume production.

At the Taiwan parent, the Technology Development organization (under Dr. Y.J. Mii) drives process node roadmap from N2 through the A14 (1.4nm) generation targeted for 2028 HVM, while Manufacturing Operations (under Y.P. Chyn) runs yield improvement and fab capacity planning across 24 fabs under construction worldwide. The Open Innovation Platform (OIP) team, which manages EDA and IP partner ecosystems, sits within Business Development under Dr. Kevin Zhang. HR (Lora Ho) and Legal (Sylvia Fang) are increasingly prominent organizational functions as TSMC navigates CHIPS Act compliance, multi-country joint venture governance, and aggressive annual headcount growth of 8–10%.
