IBM unveils claimed 0.7 nm 'sub‑1 nm' chip tech with 3D 'nanostack' transistors

IBM has announced a claimed sub-1 nm chip technology at a 0.7 nm (7 Å) node using a new three-dimensional 'nanostack' transistor architecture. The company says the design can pack nearly 100 billion transistors onto a fingernail-sized chip. Industry observers note node names are not directly comparable between vendors and questions remain about manufacturability, costs and timelines.

• IBM claims 0.7 nm 'sub‑1 nm' node using a 3D 'nanostack' transistor design
• Company says ~100 billion transistors fit on a fingernail‑sized chip
• Node naming varies across vendors; direct comparisons are unreliable
• TSMC and Intel are advancing their own nodes while commercial GPUs currently use 4 nm‑class silicon
