Semiconductor Hardware Roadmap
Process Node Evolution
Current and Future Nodes
| Node | Status | Key Players | Transistor Type |
|---|---|---|---|
| 5nm | Production | TSMC, Samsung | FinFET |
| 3nm | Production | TSMC, Samsung | FinFET/GAA |
| 2nm | Development | TSMC 2025, Intel 2024 | GAA |
| 1.4nm | R&D | TSMC 2027-2028 | GAA |
| Below 1nm | Research | Exploring CFET, 2D materials | TBD |
What "7nm", "5nm", "3nm" Mean Today Node names no longer correspond to physical transistor dimensions. They primarily indicate:
- Density: Transistors per mm²
- Performance: Speed improvements
- Power: Efficiency gains
Transistor Architecture Evolution
Planar → FinFET → Gate-All-Around (GAA) → CFET (future)
(16nm) (3nm/2nm) (sub-1nm)
