As Taiwanese chip maker TSMC ramps up production bases in the US and Japan to hedge against rising geopolitical risks, it has sparked worries back home about Taiwan’s position as the global semiconductor bastion.
But observers say it is necessary for Taiwan Semiconductor Manufacturing Co (TSMC) to move some of its operations overseas, to secure global supply chains in the face of a potential cross-strait conflict and the spillover effect of the US-China tech war.

This week, the world’s largest contract chip maker will hold a tool-in ceremony for its US$12 billion plant in Phoenix, Arizona.
