Video summary
How one impossible machine helped keep chipmaking moving
Veritasium examines the astonishing engineering behind modern chip manufacturing, from microscopic transistors to the photolithography systems that define how small chips can be made. The excerpt focuses on why Moore’s Law began to stall, and on the radical optical and materials science needed to keep chip fabrication advancing.
Chipmaking in layers
Explains how microchips are built from silicon wafers through repeated coat, expose, etch, and deposit steps.
The limits of scaling
Breaks down photolithography, diffraction, numerical aperture, and why shorter wavelengths matter for smaller features.
A machine built to beat the limits
Describes the engineering challenge of using x-ray and extreme-ultraviolet-style mirrors to push past Moore’s Law barriers.
Topics
Microchip manufacturing
A look at silicon purification, wafer creation, photoresist, etching, and metal deposition in chip fabrication.
Printing smaller chip features
An explanation of diffraction, wavelength, and numerical aperture in photolithography.
Beyond Moore’s Law
The push toward shorter wavelengths and mirror-based solutions to overcome scaling limits.

As a last step, you wash away the remaining photoresist, and now you've made a single layer of the chip. We've simplified this cycle down to the main steps, coat, expose, etch and deposit. It repeats for every single chip layer, and depending on the chip, there could be anywhere from 10 to 100 layers. The bottom layer is the transistors.
