IBM presents a revolution: chips with 0.7nm transistors — a new frontier in microelectronics
IBM Corporation has achieved a breakthrough in the semiconductor industry by announcing a chip manufacturing technology with a transistor architecture of 0.7 nanometers, equivalent to 7 angstroms. This announcement marks a shift from traditional planar circuits to a three-dimensional layout — the so-called "nanostack."
Instead of placing transistors on a single plane, IBM proposes stacking them in multiple layers. This approach radically changes the physics of chip operation, allowing it to overcome the limitations faced by modern lithographic processes. According to developers, this solution will enable a density of up to 100 billion transistors on a chip the size of a fingernail.
Comparing the new technology with the 2-nanometer process introduced by IBM in 2021, the company promises impressive metrics: a performance increase of up to 50% or an energy efficiency improvement of up to 70%. This means future processors will be able to perform twice as many operations per watt of power consumed, which is critical for data centers, mobile devices, and artificial intelligence systems.
Commercialization Prospects
IBM predicts that commercial production of chips using the 0.7 nm technology could begin within the next five years. However, the path from a laboratory prototype to mass production involves enormous technical challenges — from controlling heat dissipation in multilayer structures to adapting manufacturing equipment.
Expert Opinion: IBM's achievement is not just another generation of process technology, but a paradigm shift. The transition to a nanostack could become as pivotal a moment as the introduction of FinFET transistors ten years ago. However, investors and market participants should consider that serial production of such chips will require billions of dollars in investment in new factories, and actual implementation may extend beyond the optimistic five-year timeline.
