Taiwan Semiconductor Manufacturing Company (TSMC) Board of Directors held a special meeting on February 29 and approved the appointment of Senior Vice President of R&D Y.J. Mii and Senior Vice President of Operations Y.P. Chyn as Executive Vice Presidents and Co-Chief Operating Officers of TSMC.
The last time TSMC appointed Co-COOs were Shang-yi Chiang, C.C. Wei, and Mark Liu from March 2012 to 2013. After Chiang's retirement in October 2013, Liu and Wei were promoted to be co-CEOs. Therefore, this latest promotion has signified that Mii and Chyn have been chosen to become potential candidates for TSMC's future helmsmen.
Y.J. Mii is the Senior Vice President of Research and Development (R&D) at TSMC. Mii joined TSMC in 1994 as a manager at Fab 3 and then joined the company's R&D organization in 2001. In 2011, he was appointed Vice President of Research and Development and was later promoted to Senior Vice President in November 2016.
In more than two decades of services at TSMC, Mii made significant contributions to developing and manufacturing advanced CMOS technologies in both Fab Operations and R&D. He successfully managed the development of 90nm, 40nm, and 28nm technologies. By spearheading the research and development of 16nm, 7nm, 5nm, and beyond, he has helped maintain TSMC's technology leadership in the foundry segment of the global semiconductor industry.
Mii received the National Manager Excellence Award in 2008, recognizing his innovative "half-node" concept for 40nm process technology that improved performance and reduced die size. He also received the National Engineering Excellence Award in 2004. Before joining TSMC, Dr. Mii was a research staff member at IBM Research Center.
Mii has 34 patents globally, including 25 US patents, and holds a B.S. in electrical engineering from National Taiwan University, and an M.S. and Ph.D. in Electrical Engineering from the University of California, Los Angeles (UCLA).
Y.P. Chyn is the Senior Vice President of Operations at TSMC. He is responsible for operating and manufacturing all fabs in Taiwan and overseas. He also co-leads TSMC's Overseas Operations Office, which is responsible for supporting the company's global expansion and accelerating the organizational effectiveness of overseas operations. Before his promotion to Senior Vice President in 2016, he served as Vice President of Operations for Product Development. Before assuming that post, he was Vice President of Advanced Technology Business at TSMC, sharing responsibility for TSMC's advanced technology and 300mm fab operations.
Chyn joined TSMC when it was founded in 1987 and made significant contributions to the Company's product engineering capabilities throughout his career. He was Director of Fab 1 from 1997 to 1998, and in later positions supported yield improvement in all new generations of advanced technology, including the 28nm, 16nm, and 7nm nodes. Chyn also manages sub-nodes including N22 and N12, and the development of specialty technologies such as radio frequency, high voltage, and image sensors. Chyn pioneered the development of TSMC's Golden Spice Modeling methodology and Design for Manufacturing program.
Before joining TSMC, Chyn served as an engineer with the Industrial Technology Research Institute's Electronics Research and Service Organization (ERSO-ITRI).
The press release stated that following these appointments, the two Executive VPs and Co-COOs, as well as TSMC's HR, Finance,
Legal and Corporate Planning organizations will report directly to C.C. Wei, the company's CEO.
All other organizations will report to the two Executive VPs and Co-COOs. The new organizational structure will take effect on March 1, 2024.
