TSMC's Second Kumamoto Fab (JASM) Starts 3nm Volume Production
ESTIMATED12 months late71% CONFIDENCEOnly a year is given: Taiwan's MOEA says the fab is "scheduled to start installing equipment and come online in 2028", and C.C. Wei said on the 16 April 2026 call that "commercial production is scheduled to begin in 2028" - so the year's last day, estimated.[1]
JASM's second fab in Kikuyo, Kumamoto - switched from 6nm-class chips to TSMC's 3nm process - is due to start volume production in 2028 at 15,000 12-inch wafers a month, making Japan's first 3nm chips about a year after the end-2027 start TSMC first promised.
