TSMC Founder Says Breaking Up Chip Supply Chain Will Be Costly

(Bloomberg) -- Taiwan Semiconductor Manufacturing Co. founder Morris Chang warned that efforts by governments around the world to build domestic chip supply chains could push up costs and yet still fail to achieve self-sufficiency.

Speaking as Taiwan’s envoy to the Asia-Pacific Economic Cooperation leaders’ virtual meeting, Chang’s comments come as Taiwan’s dominant position in the semiconductor business has come under pressure, amid a widespread global chip shortage and calls in Tokyo to Washington and Beijing for domestic chipmakers to increase self-reliance.

“Free trade over the past few decades has significantly boosted the development of semiconductor technology,” Chang told reporters Friday night in Taipei. “More complex technology has led to the supply chain going offshore,” he said. “If we try to turn back the time, costs will go up, technology development will slow down.”

While not naming any specific country, Chang said governments may still not be able to build a self-sufficient supply chain after spending hundreds of billions of dollars and many years on it.

The administration of U.S. President Joe Biden is proposing a $52 billion bill to boost chip production and bolster semiconductor research and development on U.S. soil, and the European Union plans to double chip production to at least 20% of world supply by 2030. Chinese President Xi Jinping has appointed his economic czar Liu He to oversee the country’s efforts to reduce reliance on TSMC and other foreign chip companies.

Chang continued to champion the foundry business model he pioneered, which has led to global chip production to be highly concentrated in Taiwan, particularly for cutting-edge semiconductors that are used in smartphones and servers. But TSMC is now gradually departing from that path with various overseas projects. The company is building a $12 billion factory in Arizona, planning expansion in the eastern Chinese city of Nanjing, and mulling over a specialty technology plant in Japan.

Still, Chang said the old way is still the best for fulfilling global consumer demand.

“It is prudent to have a domestic, self-sufficient chip supply chain for some national-security applications. However, for the massive demand in the private sector, it is best to maintain a chip supply chain based on the free-trade system,” he said.
