How are microchips made?

Travel into a computer chip to explore how these devices are manufactured and what can be done about their environmental impact.

Globally, we produce more than a trillion computer chips every year. Which means about 20 trillion transistors are built every second— and this process is done in fewer than 500 fabrication plants. How do we build so many tiny, intricately-connected devices, so incredibly fast? George Zaidan and Sajan Saini explore how photolithography helps build these devices and its environmental impact.
