TSMC says U.S. plant construction 'more costly' than expected

TAIPEI -- Taiwan Semiconductor Manufacturing Co. on Wednesday said the cost of building its U.S. chip plant is higher than previously estimated, and again called for Washington to extend planned support for the chip industry to foreign as well as domestic companies.

TSMC Chairman Mark Liu told shareholders at the company's annual meeting that the facility in Arizona -- its first advanced chip plant in America in more than two decades -- is turning out to be "more costly" than expected, though the increase will be "manageable."
