Beyond the Silicon Wall
Chasing the next substrate: Carbon nanotubes and light-speed logic.
- Physical Limit
The Silicon Ceiling
Silicon transistors are reaching the size of atoms. When barriers are too thin, electrons simply teleport across them via quantum tunneling.
- Bottleneck
The Heat Death of Logic
We aren't just limited by size, but by heat. Current chips generate so much thermal energy they risk melting if pushed to higher speeds.
- Architecture Shift
Going Vertical
If we can't make transistors smaller, we stack them. 3D packaging turns flat chips into 'logic skyscrapers' to save precious surface area.
