TSMC’s long-rumored 1nm fab now appears to be gravitating toward Shalun in Tainan. Taiwanese officials are pointing to the new Shalun science park, near the Southern Taiwan Science Park (Nanke), as the most likely home for TSMC’s A10-era production.
TSMC still hasn’t confirmed the exact site, but this no longer looks like loose speculation. According to Taiwanese officials, feasibility work and resource planning are finished, phase two of the environmental review is in progress, and the plant is expected to take shape as a large giga-fab tied to Taiwan’s Greater Southern New Silicon Valley Promotion Plan and its southern semiconductor corridor.
If you follow CPUs, GPUs, consoles, or laptops, this matters. The Shalun park is being planned for more than just 1nm, and it lines up with TSMC’s roadmap: TSMC’s A14 is 1.4nm, TSMC’s A10 is 1nm, A14 mass production is targeted for around 2028, sub-1nm trials could follow in 2029, and A12 adds backside power delivery.
As an early sign of where future hardware is headed, this is a big one. A move to 1nm should bring faster, more efficient chips, even with scaling limits closing in, new materials and transistor designs still in play, and fab costs of roughly $32 billion making the whole thing brutally hard.
You can also expect the Shalun site to draw in robotics, optoelectronics, precision machinery, biotech, and aerospace suppliers, while Samsung, Rapidus, and governments in the US, Japan, and South Korea race toward the same frontier.
