Claims
- IBM has announced a 0.7nm chip technology, marking the world's first sub-1 nanometer chip.
- A 0.7nm scale is approximately 100,000 times thinner than a human hair, representing only a few atoms across.
- The new chip architecture shifts from treating miniaturization as a flat-layout problem to a vertical stacking approach.
Key quotes
IBM debuts world's first sub-1 nanometer chip.
0.7nm is about 100,000 times thinner than a human hair, only a few atoms across as a technology marker.
It stops treating smaller chips as a flat-layout problem and starts stacking.
