The design stacks and staggers transistors vertically in two bonded layers, using an ultra-thin dielectric material to separate them.<\/p>\n<p>That approach differs fundamentally from the nanosheet technology IBM pioneered and the broader industry adopted. Nanosheets compressed features in two dimensions. Nanostack adds density in a third.<\/p>\n<p>\u201cWe\u2019re not just making smaller transistors, we\u2019re reinventing how chips are built to deliver dramatically more power and energy efficiency,\u201d said Jay Gambetta, Director of IBM Research and IBM Fellow.<\/p>\n<h2>What the Numbers Show<\/h2>\n<p>IBM\u2019s published technical results, presented at VLSI 2026, report the following compared to IBM\u2019s 2 nm chip from 2021:<\/p>\n<ul>\n<li aria-level=\"1\">Nearly 2x transistor density<\/li>\n<li aria-level=\"1\">Up to 50% more performance<\/li>\n<li aria-level=\"1\">Up to 70% greater energy efficiency<\/li>\n<li aria-level=\"1\">40% improvement in SRAM scaling<\/li>\n<\/ul>\n<p>The SRAM gain matters specifically for <a href=\"http:\/\/news.bitcoin.com\/14-ai-models-including-claude-chatgpt-and-grok-predict-bitcoins-price-outlook\/\">AI<\/a> workloads. On-chip memory bandwidth is a limiting factor for AI accelerators, and better SRAM scaling lets chip designers fit more memory closer to the processor without adding area or power draw.<\/p>\n<h2>Why the 0.7 nm Label Needs Context<\/h2>\n<p>Modern process <span>node<\/span> numbers no longer correspond to literal physical dimensions. The transistor channel layers in IBM\u2019s nanostack design measure roughly 5 nanometers thick, or about 15 silicon atoms. The 0.7 nm designation reflects the density and performance generation, not a direct measurement of every feature on the chip.<\/p>\n<p><a href=\"http:\/\/news.bitcoin.com\/ibm-quantum-hardware-cracks-15-bit-ecc-key-but-bitcoin-devs-say-random-bits-match-the-result\/\">IBM<\/a> acknowledged this directly. The company\u2019s position is that the nanostack method delivers the effective gains expected from sub-1 nm scaling by going vertical rather than by shrinking every dimension closer to atomic limits.<\/p>\n<h2>A Path Forward for Moore\u2019s Law<\/h2>\n<p>The semiconductor industry has faced mounting pressure as traditional two-dimensional shrinking hits physical constraints, including quantum tunneling, heat dissipation, and manufacturing cost. The pace of gains from pure lithography improvements has slowed.<\/p>\n<p>IBM\u2019s approach addresses this by adding density through 3D sequential integration. The company projects the nanostack architecture can support at least a decade of continued scaling from this point.<\/p>\n<p>Dan Hutcheson of Techinsights <a href=\"https:\/\/www.technologyreview.com\/2026\/06\/25\/1139696\/ibm-unveils-sub1nm-chip\/\" target=\"_blank\" rel=\"noopener noreferrer\">said<\/a> the development puts \u201canother 10, 15 years on the roadmap.\u201d<\/p>\n<p>Major competitors like Intel, Samsung, and TSMC are pursuing related three-dimensional transistor strategies, including complementary FET designs. IBM\u2019s announcement represents a working demonstration of a verified path at the sub-1 nm threshold.<\/p>\n<h2>The Albany Research Ecosystem<\/h2>\n<p>IBM conducts this work alongside partners including Lam Research, Tokyo Electron, and SCREEN Semiconductor Solutions. The Albany facility will also house a High Numerical Aperture Extreme Ultraviolet lithography tool from ASML, a system required for the next phase of logic scaling.<\/p>\n<p>IBM separately announced plans to form Anderon, a standalone quantum foundry intended to manufacture quantum wafers at commercial scale.<\/p>\n<h2>Timeline to Production<\/h2>\n<p>The nanostack chip remains a research prototype, though IBM confirmed it has demonstrated functional CMOS inverter operation with expected switching performance. IBM sees a path to production adoption in as early as five years, or roughly 2031.<\/p>\n<p>The announcement does not signal an imminent product release. It signals that the industry\u2019s next generation of hardware has a viable structural foundation.<\/p>\n<\/div>\n<p><a href=\"https:\/\/news.bitcoin.com\/ibm-unveils-sub-1-nanometer-chip-with-100-billion-transistors-extending-moores-law-37856\/\" class=\"button purchase\" rel=\"nofollow noopener\" target=\"_blank\">Read More<\/a><br \/>\n Jamie Redman<\/p>\n","protected":false},"excerpt":{"rendered":"<p>IBM on Thursday unveiled the world\u2019s first sub-1 nanometer chip technology, a research prototype at the 0.7 nanometer node that packs nearly 100 billion transistors onto a chip the size of a fingernail.
