“However, as TSMC researchers acknowledge, the 1-nm process node is not likely to be used for years to come.”
The breakthrough is a bismuth contact on 2D materials from a lab at MIT and NTU. The headline turns that into a 1 nm chip. TSMC hasn’t shipped 3 nm in volume yet and 2 nm is a 2025 promise. Node names stopped meaning physical size years ago. This is a research paper wearing a roadmap costume.
