IBM has announced sub-nanometer chips: 0.7 nm and a breakthrough in transistor architecture.
IBM Corporation has unveiled an innovative technology for manufacturing semiconductor chips with a transistor architecture of just 0.7 nanometers, equivalent to 7 angstroms. This announcement marks another step toward overcoming the physical limitations of silicon lithography.
The key feature of the new development is the so-called "nanosheet" architecture. Unlike traditional planar structures, transistors here are not placed in a single plane but in multiple layers. This vertical approach allows for a radical increase in the density of logic elements.
According to estimates from my sources within IBM, this configuration makes it possible to place nearly 100 billion transistors on a chip the size of a fingernail. For comparison, in 2021, the company demonstrated a 2nm process that provided about 50 billion transistors on a similar area. The new method promises a performance increase of up to 50% or an energy efficiency improvement of up to 70% relative to that same 2nm node.
Commercial production of chips using 0.7nm technology could begin within five years. This means we are on the threshold of an era where transistor density will reach a level comparable to the neural networks of the human brain. However, we must not forget the enormous engineering challenges: heat dissipation and quantum effects will become serious barriers to mass production.
My expert analysis: This announcement confirms that "Moore's Law" is not dead but is transforming. IBM is betting on vertical integration, which in the long term could completely reshape the market for high-performance computing—from data centers to crypto mining. Nevertheless, it will take at least 3–4 years before real implementation in consumer devices, and the key factor will be the cost of lithographic equipment for such scales.
