TSMC chairman Morris Chang, 86, who will retire in June 2018, predicts the facility may cost upwards of $20 billion:
“By the time we’re through, by the time we’ve built all the necessary capacity, I think we would have spent upwards of $15 billion,” said Chang, who’s calling it quits in June and handing the reins of his $190 billion-plus company to lieutenants Mark Liu and C.C. Wei. “That’s a conservative estimate. Maybe it’s safer to say upwards of $20 billion."
