C. C. Wei: Born 1953, from NCTU Electronics to Yale PhD to TSMC Chairman and President

30-second overview: C. C. Wei was born in 1953. He studied at National Chiao Tung University (NCTU), earning both his bachelor's and master's degrees in Electronics Engineering, then went to the United States to obtain a Ph.D. in Electrical Engineering from Yale University.¹ His career spans Texas Instruments, STMicroelectronics, and Chartered Semiconductor Manufacturing in Singapore before he joined TSMC in 1998.¹ In 2012, he was appointed co-Chief Operating Officer of TSMC alongside Mark Liu.² On June 5, 2018, following the retirement of founder Morris Chang, Wei assumed the role of Vice Chairman and President of TSMC.² On June 4, 2024, after Mark Liu's retirement, Wei officially became Chairman of TSMC, and currently serves as both Chairman and President.³

Born 1953, NCTU Electronics Engineering

C. C. Wei was born in 1953 and studied Electronics Engineering at National Chiao Tung University, completing both his bachelor's and master's degrees there.¹ He then went to the United States to pursue a Ph.D. in Electrical Engineering at Yale University, after which he entered the semiconductor industry.¹

(Note: Some sources incorrectly list his birth year as 1955 and his education as a degree in Materials Science from National Taiwan University plus a Stanford Ph.D. Neither claim is consistent with P0-verified records. The correct credentials are NCTU Electronics + Yale Ph.D. in Electrical Engineering.)

Career Path Before Joining TSMC: TI, ST, Chartered

Before joining TSMC in 1998, Wei held positions at Texas Instruments, STMicroelectronics, and Chartered Semiconductor Manufacturing in Singapore, accumulating diverse experience in semiconductor design, process development, and corporate operations.¹

The significance of these pre-TSMC years is often underestimated. Texas Instruments is a godfather of the global semiconductor industry; STMicroelectronics spans Europe and Asia; Chartered Semiconductor Manufacturing was a major player in Asia-Pacific foundry services. Wei was shaped across three companies of different scales and cultures, and it was with this global perspective that he entered TSMC.

Upon joining TSMC in 1998, he took on R&D-related roles and gradually led the development of advanced process technologies across multiple critical nodes, from 90 nm down to 3 nm.

The historical significance of this process leadership lies in the fact that TSMC's ability to ramp mass production ahead of schedule at every key node was underpinned by the R&D team's mastery of engineering decision-making. Within that system, Wei was a technology decision-maker, not merely a manager; this distinction shaped both his leadership style and the external trust placed in him when he later assumed the presidency.

Appointed Co-COO of TSMC Alongside Mark Liu

In 2012, Wei and Mark Liu were jointly promoted to co-Chief Operating Officers of TSMC, establishing the collaborative foundation of a dual-leadership structure.²

Common narrative → More precise reading: TSMC's "dual-leadership model" is often interpreted as a power-sharing or transitional arrangement. But in hindsight, it was a carefully designed succession mechanism by Morris Chang: two candidates working within the same framework, complementing each other, with the organization itself determining who was better suited for the chairmanship.

Assuming Vice Chairman and President: The Dual-Leadership Structure After Morris Chang's Retirement

On June 5, 2018, TSMC founder Morris Chang retired, and Wei assumed the role of Vice Chairman and President, co-leading the company with Chairman Mark Liu.² Their division of responsibilities was clear: Liu focused on the board of directors and external strategy, while Wei led technology development and day-to-day operations.

This period of shared leadership (2018–2024) was a critical test for TSMC entering the "post-Morris Chang era": external geopolitical pressures escalated sharply, and the customer landscape became politically more complex than ever before. Against this backdrop, Wei drove the technology roadmap and process-related capital expenditure, serving as the core executor enabling TSMC's continued advancement in leading-edge process technology.

Assuming the Chairmanship: 26 Years of Accumulation and the New Challenge of Three-Continent Fabs

On June 4, 2024, Mark Liu formally retired, and Wei succeeded him as Chairman of TSMC while retaining the title of President, now serving as both Chairman and President.³ This was the position he reached after 26 years at TSMC, and at the most geopolitically complex moment in the company's history, with TSMC simultaneously advancing fab construction projects in the United States, Japan, and Germany.

Since assuming the chairmanship, Wei has repeatedly emphasized TSMC's technology leadership and the importance of maintaining existing customer trust in public appearances, continuing the "technology without political alignment" operational framework established by his predecessor.⁴

After 2024, TSMC's fab construction plans in Arizona (USA), Kumamoto (Japan), and Dresden (Germany) advanced in parallel. For a leader rooted in "technology culture," this presented an entirely new external challenge: managing political expectations across multiple geographies alongside engineering execution standards. This was the most immediate test Wei faced upon taking the chairmanship.

🎙️ Curator's note: C. C. Wei is a product of TSMC's "technology culture," not its "diplomacy culture." Mark Liu excelled at external communication; Wei's foundation is that of an engineer, which suggests that TSMC's next chapter of leadership may lean more toward internal convergence on technology decisions rather than external narrative output.

From NCTU's Electronics Department to a Yale Ph.D., and from formative years at Texas Instruments to 26 years at TSMC, Wei's path is one of accumulation without shortcuts: each title was a natural extension of the one before, ultimately leading him to the top of the world's most important semiconductor company.
