The transistor, invented at Bell Labs in 1947, and subsequent semiconductor technology created the foundation for all modern computing. This episode explains the physics of semiconductors and why they were so revolutionary compared to vacuum tubes—they were smaller, more reliable, generated less heat, and consumed far less power. We trace the evolution from discrete transistors to integrated circuits, where multiple transistors were combined on a single chip, exponentially increasing processing power while decreasing size and cost. The episode examines how semiconductor manufacturing became a…
