Carbon Nanotube 'Sandpaper' Polishes Chips to Atomic Precision
Key Takeaways
- Engineers develop carbon nanotube-based polishing pads that achieve atomic-level surface flatness on semiconductor wafers
- The technique achieves sub-nanometer variation across entire wafers, exceeding what current industry methods can reliably deliver
- As chips approach 2nm and angstrom-era nodes, even a single misplaced atom can alter transistor electrical properties
