Asian Tech Press (June 20) -- TSMC is preparing to build four more fabs in Taiwan in order to produce 3nm chips.

After the completion of four new facilities in the Tainan City Industrial Area, TSMC is starting construction of four more fabs in Taiwan as part of TSMC's manufacturing hub.

Each construction project will cost TSMC about $10 billion, part of a $120 billion investment by the world's largest chipmaker.

All four new projects feature production lines for 3-nanometer chips. Products that TSMC could produce at the plants in the future include Apple's SoCs, including Apple Silicon and A-series chips.

TSMC also said on Friday that it plans to achieve mass production of 2nm chips by 2025.

According to TSMC's plan, it will build at least 20 wafer fabs in Taiwan, some under construction and some already completed.
