TSMC Targets Sub-1nm Era, After Breakthrough 1.4nm Chip Industry Enters New Phase

Jakarta - Global chip miniaturization ambitions have not shown signs of slowing down. TSMC is now reportedly starting to focus on sub-1 nanometer technology, surpassing the 2nm roadmap that has been the industry's target.

According to a report by DigiTimes, the Taiwanese semiconductor giant is targeting trial production of sub-1nm chips around 2029. Previously, the 1.4nm fabrication process - known as A14 - was projected to enter mass production in 2028.

Node 1.4nm is claimed to be able to bring performance and efficiency improvements of around 30 percent. A figure that, in the context of modern computing, can be a big differentiator - especially in the era of artificial intelligence and high-performance computing explosions.

However, the sub-1nm phase won't go live on a large scale immediately. Initial production is said to be only around 5,000 wafers per month, more as a stage of testing the technology than full commercial production.

To support this ambition, TSMC will rely on its production facilities in Tainan, including the A10 plant and related manufacturing ecosystems. This infrastructure is an important foundation for overcoming the complexity of technologies below 1nm - a region that is technically increasingly challenging.

On the demand side, this development is in line with the needs of the industry, especially from the AI and high-performance computing sectors which continue to pursue energy efficiency as well as increased computing power.

Apple is expected to be one of the first customers for this latest node, given its track record of frequently adopting the most advanced fabrication technology from TSMC. It is not impossible that sub-1nm chips will debut in the MacBook line towards the end of the decade.

However, the road to sub-1nm is not without obstacles. TSMC still has to stabilize the 1.6nm and 1.4nm processes first. Technical challenges such as production yield, limitations of EUV lithography, to heat management are crucial factors that can affect the timeline.

In other words, this roadmap is ambitious - and as usual in the semiconductor industry, the realization in the field may shift. But one thing is clear: the race for smaller, faster, and more efficient chips is still far from the finish line.
