Taiwan to keep best TSMC tech despite US push

The Executive Yuan on Thursday said it would work to ensure that Taiwan Semiconductor Manufacturing Co’s (TSMC) most advanced technology remains in Taiwan after the chipmaker announced plans to invest an additional US$100 billion in the US.TSMC chairman C.C. Wei (魏哲家) announced earlier on Thursday that the company would invest an additional US$100 billion in Arizona to build four more advanced wafer and packaging facilities, on top of a previous US$165 billion investment commitment in the state.The pledge compounded concerns in Taiwan that its edge in advanced semiconductors would be eroded as it invested more abroad, especially as Washington insists that more of the world’s semiconductors be manufactured in the US.
