- The evolution from vacuum tubes to transistors and integrated circuits (ICs) marked the beginning of semiconductor scaling.
- Bell Labs played a pivotal role in the invention of the transistor, replacing unreliable vacuum tubes with solid-state electronics.
- The transition from germanium to silicon and the development of photolithography and the planar process were crucial for IC manufacturing.
- Jack Kilby and Robert Noyce independently developed the first integrated circuits, with Noyce's design being more practical for mass production.
- The invention of the MOSFET transistor and CMOS technology enabled significant advancements in power efficiency and miniaturization.
- Scaling progressed from Small Scale Integration (SSI) to Very Large-Scale Integration (VLSI), leading to modern System-on-Chip (SoC) designs with billions of transistors.
- SoCs face challenges such as high design complexity, manufacturing costs, and yield issues as transistor sizes approach physical limits.
- Chiplets are emerging as a solution to overcome the limitations of monolithic SoCs, offering potential benefits in cost, performance, and flexibility.
