Study Notes
Moore's Law: The Journey Ahead
- Moore's Law, initially focused on transistor count reduction, is now viewed as focusing on increasing computational rate rather than density.
- Transistor scaling has slowed due to issues with smaller transistors functioning effectively at shorter channel lengths, leading to quantum tunneling effects and degradation of performance metrics (on-current should be high, off-current low).
- Current transistor platforms leverage improvements to reduce off-current and leakage (e.g., strained silicon, high-k gate insulators, FinFETs).
- Three approaches can extend Moore's law; 2D nanoelectronics, 3D terascale integration, and functional integration.
2D Nanoelectronics
- Challenges include eventual electron tunneling; limitations due to size reduction.
3D Terascale Integration
- Aims to increase transistor count through monolithic integration or stacking.
- Challenges include heat dissipation, process integration, lithography and reliability issues.
Functional Integration
- Enhances functionality by integrating sensing, actuation, and data analytics with commercial ICs.
- This method improves processing performance by transferring information instead of raw data.
Transistor Scaling Limitations
- Manufacturing fabrication methods face cost and complexity increases as transistors become smaller
- Heat dissipation challenges are magnified in densely packed 3D architectures.
Design Challenges
- Maintaining interconnect alignment across 3D structures is critical.
- Thermal management is critical for maintaining reliability and performance in dense 3D architectures.
- Reliability needs assessment at a higher scale to ensure longer-term stability; accelerated testing is not sufficient.
Future Directions
- Shifting focus from reducing transistor size (nanoelectronics) to increasing transistor count and related functionality (terascale electronics).
- Machine learning can reduce design cost and improve chip designs.
- Emphasis on hardware acceleration of specific functions as companies adopt custom chip designs for specific requirements.
- Continued progress requires development in materials science, devices, processing, and design of complex chips.
