Can Taiwan's Silicon Shield Protect It against China's Aggression? Joyce Huang TAIPEI - The global shortage of semiconductors, or microchips -- the "brains" in all electronic devices, has heightened the geopolitical significance of Taiwan and its chip-making sector. The island is home to the world's largest contract chipmaker: Taiwan Semiconductor Manufacturing Co (TSMC). Many describe Taiwan's strength in microchips as its "silicon shield," which can protect it against Chinese aggression. But others suspect the sector, coveted by China, may also trigger China to accelerate its efforts to take advantage of Taiwan's tech prowess. 'Not let war happen' When asked to explain the shield, TSMC chairman Mark Liu told CBS News' "60 Minutes" program last week that it means "the world all needs Taiwan's high-tech industry support. So, they will not let the war happen in this region because it goes against interest of every country in the world." While refusing to comment on whether the industry will keep Taiwan safe, Liu added that he hoped no war would occur in Taiwan. It is widely believed that any war fought in Taiwan could disrupt the global supply chains of microchips. More than 1 trillion chips are currently being produced annually. Industry watchers, including the National Bank of Canada estimated earlier that TSMC alone accounts for one-fifth of the world's chip production and up to 90% of the supply of the most advanced chips. In an "extremely hypothetical scenario," such a disruption in Taiwan's chip production could cause $490 billion in annual losses for electronic device makers worldwide, according to estimates by the U.S.-based Semiconductor Industry Association last month. All shut down American tech giants including Apple, major European auto makers and even Chinese companies would have to halt production in the event of a TSMC collapse, said Frank Huang, chairman of Taiwan's third-largest chipmaker Powerchip Semiconductor Manufacturing Corp. That, he said, will make China think twice about using force against Taiwan, the self-ruled island Beijing views as a renegade province.
