Episode notes
Silicon's Significance
- Silicon's atomic structure and unique properties enable efficient transistors.
- This allows for miniaturization and performance improvements described by Moore's Law.
Scaling and Moore's Law
- Transistor size has consistently decreased, leading to increased computational power.
- Seven-nanometer transistors represent the current state-of-the-art, with only tens of atoms along the conduction path.
Chip Fabrication
- Chip fabrication involves photolithography and ion implantation to create precise patterns on silicon wafers.
- This process allows for mass production of complex chips with billions of transistors.
