TSMC reportedly cuts 28nm output by over 25% since early 2026 as advanced node push accelerates

As TSMC ramps up 2nm and 3nm production, it is also accelerating the phaseout of legacy nodes. Commercial Times, citing supply chain sources, reports that monthly wafer starts at Fab 15A, TSMC’s primary 28nm site, have dropped by more than 25% since the start of the year. The pullback in 28nm production also aligns with a broader transformation of Fab 15A.
