How Microchips Are Made: From Sand to Silicon

It is smaller than a fingernail, yet it holds billions of switches — and it begins as sand. Follow the journey of a microchip: from quartz quarries and glowing arc furnaces to silicon purified to one foreign atom in a billion, a single perfect crystal pulled from molten silicon, wafers polished flatter than almost anything on Earth, and cleanrooms where machines print circuits with light hotter than the Sun. How many steps does a chip take? How small are its parts? And why did a shortage of these tiny squares stop car factories? Industrial Giants takes you inside the world's mightiest factories and machines, told like a nature documentary. 🔔 Subscribe to Industrial Giants for new episodes. ⏱ Chapters 00:00 Billions of Switches 00:23 From Quartz 00:39 Furnaces of Silicon 00:56 Purer Than Pure 01:11 Growing a Crystal 01:52 The Ingot 02:07 Wafers 02:26 The Cleanroom 02:46 Printing With Light 03:07 Hotter Than the Sun 03:31 Layer by Layer 04:08 Copper Highways 04:21 Rainbow Wafers 04:35 Packaging & Testing 05:08 Ones and Zeros 05:23 Doubling Every Two Years 05:42 Giant Fabs 06:11 Chips Everywhere 06:42 A Grain of Sand ℹ️ About this video Visuals are AI-generated illustrations created for storytelling.
