TSMC's Second Arizona Fab Starts Mass Production
ESTIMATED72% CONFIDENCETSMC[2] said it had "pushed up the mass production schedule for its second wafer fab in the U.S. state of Arizona to the second half of 2027 from the previously planned 2028," naming a half-year rather than a day.
The second fab on TSMC's north Phoenix campus, whose structure was finished in 2025, is due to begin high-volume manufacturing in the second half of 2027 - a year earlier than the schedule the company had previously given. Chairman C.C. Wei gave the pulled-forward date on 15 January 2026; the campus is the centrepiece of a $165 billion Arizona investment.
