IBM Unveils World’s First Sub-1nm Chip Technology with ‘Block of Flats’ 3D Design
Core Summary
IBM has announced that its research team has successfully created the world’s first known working chip technology below one nanometre. The breakthrough uses an innovative three-dimensional stacking design that researchers have likened to a “block of flats” — stacking transistors vertically like apartment floors to pack more computing power into an incredibly tiny space. However, IBM cautioned that the technology is still some time away from mass production.
Event Details
According to BBC Technology, IBM’s published results mark the semiconductor industry’s entry into an entirely new technological era. One nanometre equals one-billionth of a metre — tens of thousands of times thinner than a human hair. Building functional transistors at this scale has long been considered a challenge at the limits of physics.
IBM’s team adopted a novel transistor architecture called Gate-All-Around (GAA), combined with carbon nanotube materials, to achieve stable electrical performance at the sub-1nm node. The team nicknamed the design the “block of flats” approach — just as cities build upward to house more residents, chip designers stack multiple layers of transistors vertically to fit more computing units onto a limited chip area.
In a technical statement, IBM said the achievement proves that precise material manipulation at the atomic scale is feasible, laying a scientific foundation for commercial chip manufacturing in the next five to ten years. However, a vast engineering gap remains between laboratory results and factory-scale production, requiring solutions for yield, cost, and scalable manufacturing challenges.
Panoramic Perspective
This breakthrough carries profound implications for the strategic landscape of the global semiconductor industry. Currently, TSMC, Samsung, and Intel are fiercely competing at the 3nm to 1.8nm process nodes, while IBM’s sub-1nm result pushes the technology frontier forward by a significant leap.
From a geo-technology standpoint, continued chip miniaturisation is essential for sustaining the global digital economy. The exponential growth in AI model parameters demands unprecedented computing power, and more advanced processes mean greater computational capability at the same power consumption — critical for nations maintaining their lead in the AI race.
Notably, this achievement also underscores the irreplaceable value of fundamental research in corporate R&D. In an era where the semiconductor industry increasingly relies on massive production investment, IBM’s research laboratories continue to demonstrate the ability to explore physical limits — a model combining basic research with engineering application that merits deep industry reflection.
Multiple Perspectives
Semiconductor industry analysts widely agree that while IBM’s breakthrough is encouraging, the translation from lab to mass production typically requires a three-to-five-year conversion cycle. Some experts point out that achieving large-scale consistency in carbon nanotube material fabrication remains a primary bottleneck.
On the other hand, technologically optimistic researchers believe this result proves Moore’s Law has not reached its end, and the possibility of atomic-scale precision manufacturing injects new confidence into the entire industry. IBM stated it will continue advancing the engineering of this technology with partners.
