TSMC Plans Second 3nm Fab in Tainan, Evertiq Reports

TSMC will build another 3nm fabrication plant in Tainan, southern Taiwan, Evertiq reports. The plan extends the company's advanced-node capacity at the site where its first 3nm production lines already operate.

The decision places additional leading-edge capacity in Tainan rather than at other locations in TSMC's manufacturing network. The company runs its 3nm process, designated N3, at the Southern Taiwan Science Park, and the new fab would expand that cluster.

What does the additional fab mean?

Evertiq's report gives no construction schedule, investment figure or capacity target for the planned plant. The announcement itself carries weight: 3nm capacity remains the tightest segment of the foundry market, and Apple, as the first and largest N3 customer, absorbs the majority of current output.

Each additional 3nm fab concentrates more of the world's most advanced logic supply in a single metropolitan area. TSMC produces virtually all global 3nm output today.

In plain words: TSMC is doubling down on Tainan for its most advanced chips.
