According to unconfirmed media reports, TSMC is planning to build a massive semiconductor manufacturing facility in southern Taiwan with 1-nanometer structure sizes. "Fab 25" is expected to operate up to six production facilities for 300-mm wafers.

The world's leading semiconductor contract manufacturer, Taiwan Semiconductor Manufacturing Co. (TSMC), is reportedly planning to build a 1-nm "Gigafab" for semiconductors near Tainan in Taiwan. This was reported by the Taiwanese newspaper United Daily News, citing unidentified insider sources. The Gigafab is said to be located in the Shalun Industrial Park in southern Taiwan.

According to the report, the planned Fab 25 is to house six production lines for 300-mm (approx. 12 inch) wafers. TSMC neither confirmed nor denied the decision to the newspaper. However, it seems likely that the construction of the 1-nm (approx. 0,04 inch) Gigafab in Taiwan is being firmly pursued, but the final decision on the choice of location is still pending. "The company uses Taiwan as the main location and does not rule out any possibility," the article states.

As the United Daily News reports, TSMC has proposed to the Southern Taiwan Science Park Administration in Shalun the construction of a 1.4-nm (approx. 0,05 inches) and 1-nm fab at the site. According to the report, the planned production lines P1, P2, and P3 will initially produce semiconductors using the 1.4-nanometer process. The production lines P4, P5, and P6 will subsequently be dedicated to the more advanced 1-nanometer technology. However, plans remain open depending on the advancement of technologies: it is conceivable that production lines P1 to P3 could already introduce the 1-nm technology, and the later lines P4 to P6 could already start a 0.7-nanometer (approx. 0,03 inch) manufacturing process.

A timeline for the construction of Fab 25 was not provided. The United Daily News reports that this plan would demonstrate TSMC's determination to remain in Taiwan and develop its cutting-edge processes there. Although the company has made several investments abroad in recent years, including in the USA, Japan and Germany, they remain committed to manufacturing cutting-edge technologies exclusively within Taiwan.
