Taiwan Semiconductor Manufacturing Co (TSMC) on May 15 announced that it would build an advanced semiconductor fab that would mainly deploy 4-nanometer process technology in Phoenix, Arizona.
Most Taiwanese are not aware that Phoenix has become an important chip manufacturing center in the US. Although South San Francisco in the Bay Area is known as Silicon Valley, the tech industry there today has little to do with silicon, or chip, production, except for a few old Intel fabs. Instead, it is more focused on upstream semiconductor industries, such as the Internet, biotech, green energy and artificial intelligence.
Apple, for example, designs its own mobile phones; Google designed a tensor processing unit for artificial intelligence (AI); Nvidia’s graphics processor has been widely adopted by AI, blockchain and bitcoin companies around the world in the past few years. These upstream companies own highly innovative technologies and they basically outsource all their manufacturing to companies like TSMC or United Microelectronics Corp (UMC).
TSMC, which has more than nine advanced IC fabs in Taiwan, is the world’s largest contract chipmaker with the most advanced manufacturing quality. However, in other US high-tech sectors, such as defense, space technology, medical equipment, 5G and self-driving vehicles, plants capable of supplying small batches of high-tech chips are still in demand.
TSMC’s decision to build a fab in the US is clearly based on the huge potential it sees for providing its professional services locally. Regardless of how much political pressure from the US and Taiwanese governments was behind TSMC’s decision, it is a milestone in the internationalization of Taiwan’s technology industry. Past governments have encouraged Taiwanese companies to make global deployments, but without the leading companies taking the lead, who would dare to go it alone?
TSMC aims to start detailed plans for its Phoenix facility next year and to complete construction in 2022-2023, with 4-nanometer chip production targeted to begin in early 2024.
TSMC has a fab in the Southern Taiwan Science Park that has started mass production of 5-nanometer chips. Its plan to set up a more advanced fab deploying 2 to 3-nanometer process technology in Kaohsiung’s Luzhu Science Park has already been approved by the government.
With the emergence of a large number of new technologies, demand for high-end applications is expected to focus on 4 to 7-nanometer chip technology within the next five to seven years. TSMC’s main competitors, such as Samsung and Intel, are doing their utmost to catch up, making 4 to 7-nanometer technology their focus for the next 10 years.
TSMC’s bold plan to build its second 4 to 5-nanometer fab on US soil to be closer to potentially huge new customers is a wise and timely move. Building an advanced fab in the US is based on several important strategic considerations.
First, separating production sites and capabilities is an attempt to reduce the risk of becoming involved in the intensifying US-China technology dispute.
Second, continuing to boost investment in high-end process technologies would help TSMC maintain its leading status in the industry in the long term.
Third, top US university laboratories are leading the world in the research and development of new materials, precision optics, communication technology and digital healthcare, providing geographical proximity for the TSMC US fab to develop next generation 1-nanometer technology.
Sustainable development of an enterprise requires continuous efforts by generations of talent. TSMC founder and former chief executive Morris Chang (張忠謀) achieved great things, and the two co-CEOs who took over are also doing a good job.
It has been said that TSMC is a black hole that sucks in Taiwan’s high-end talent as one of every two graduates from the master’s or doctoral programs of the nation’s four top technology universities end up working for TSMC.
However, this top talent, who are now over the age of 40 and have been trained by TSMC for more than 15 years, are not like their predecessors from the two previous generations, who studied in the US and had experience working in large global companies. The question now is how to better equip them to lead this world-leading enterprise. Transferring them to Phoenix would clearly be a feasible shortcut to giving them the training and experience they need.
From another perspective, building TSMC’s second 4-nanometer plant in Phoenix would release 3,000 to 4,000 graduates from Taiwan’s elite universities to the job market. This would boost the workforce needed by other enterprises with high potential. This group represents Taiwan’s top science and engineering talent, and they would be a great human resources asset to Taiwan and a positive force to transform and upgrade the nation’s industry and enhance its international competitiveness.

We are used to hearing that whenever something happens, it means Taiwan is about to fall to China. Chinese President Xi Jinping (習近平) cannot change the color of his socks without China experts claiming it means an invasion is imminent. So, it is no surprise that what happened in Venezuela over the weekend triggered the knee-jerk reaction of saying that Taiwan is next. That is not an opinion on whether US President Donald Trump was right to remove Venezuelan President Nicolas Maduro the way he did or if it is good for Venezuela and the world. There are other, more qualified
This should be the year in which the democracies, especially those in East Asia, lose their fear of the Chinese Communist Party’s (CCP) “one China principle” plus its nuclear “Cognitive Warfare” coercion strategies, all designed to achieve hegemony without fighting. For 2025, stoking regional and global fear was a major goal for the CCP and its People’s Liberation Army (PLA), following on Mao Zedong’s (毛澤東) Little Red Book admonition, “We must be ruthless to our enemies; we must overpower and annihilate them.” But on Dec. 17, 2025, the Trump Administration demonstrated direct defiance of CCP terror with its record US$11.1 billion arms
The immediate response in Taiwan to the extraction of Venezuelan President Nicolas Maduro by the US over the weekend was to say that it was an example of violence by a major power against a smaller nation and that, as such, it gave Chinese President Xi Jinping (習近平) carte blanche to invade Taiwan. That assessment is vastly oversimplistic and, on more sober reflection, likely incorrect. Generally speaking, there are three basic interpretations from commentators in Taiwan. The first is that the US is no longer interested in what is happening beyond its own backyard, and no longer preoccupied with regions in other
As technological change sweeps across the world, the focus of education has undergone an inevitable shift toward artificial intelligence (AI) and digital learning. However, the HundrED Global Collection 2026 report has a message that Taiwanese society and education policymakers would do well to reflect on. In the age of AI, the scarcest resource in education is not advanced computing power, but people; and the most urgent global educational crisis is not technological backwardness, but teacher well-being and retention. Covering 52 countries, the report from HundrED, a Finnish nonprofit that reviews and compiles innovative solutions in education from around the world, highlights a
