Reason 2: The end of semiconductor scaling
Reasonable projections (Hu, Mead)
- We will engineer devices down to a 0.03µm channel length
- ~10 more year of scaling
Projected transistor density at a 0.03µm: 5 million / mm2
- A chip will have ~ 1billion transistors
- The limitations?
- Zero error tolerance
- Energy losses
- Interconnect
