How Do Transistors Work? At its core, a transistor is an electronic gatekeeper. It controls the flow of electric current through a semiconductor material.

Home > Science What Is a Transistor, and How Does It Work? Join us for a deep dive into the tiny technology that powers the world.

Transistors are fundamental to modern electronics for several reasons: Miniaturisation: Transistors are significantly smaller than their predecessors, vacuum tubes.

Without transistors the modern world would simply not exist. But how do they work, and how do modern, atomic sized versions compare with the originals?

In DRAM chips, besides access transistors, peripheral transistors must meet stringent requirements which preclude a ‘copy-paste’ of regular logic transistor process flows.

Of the five transistors inside, some were alloyed transistors, and some were grown crystals. The factory had to hand-select crystal transistors to make each unit work.
