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.

Audience comments snapshot
Audience comments summary
Commenters are especially struck by how unreal the machine looks in practice, with several calling it more sci-fi than fiction. A number of viewers also connect the video to real-world chipmaking work, including people saying they work at or around ASML and feeling excited or proud to see the company featured. Another visible thread is light, celebratory humor around the Dutch setting and the rarity of hearing Dutch speakers converse in English, along with a few broader reflections on how far materials and technology have come.
Comment themes
Awe at extreme engineering
The sample is dominated by admiration for the complexity and reality of the machine, with commenters repeatedly expressing disbelief at how advanced it is.
Industry identification
A smaller but notable cluster comes from people who identify with ASML or nearby work, giving the discussion a personal, insider feel.
Playful regional references
Humor and national identity appear in several replies, especially around Dutch speakers and the Dutch company behind the technology.
Audience signals
Machine seen as sci-fi
Multiple comments emphasize that the machine feels astonishingly futuristic despite being real.
ASML connection
Viewers with ASML ties say they were excited or proud to see their workplace or role represented.
Dutch-themed humor
Several comments joke about the Dutch people and Dutch company appearing in an English-language video.
Long-view technology reflection
One comment frames the technology as part of a long historical arc from ancient tin use to modern chipmaking.

I’m an ASML engineer and have been following veritasium for more than a decade. Seeing this video in my feed made me extremely happy
This thing is genuinly way more sci-fi than most sci-fi machines yet it actually exists.
You did it Derek, you made two dutch guys talk to each other in English.
As an ASML janitor I’m really proud of being part of keeping pretty clean around here!!!
Tin had such a crazy ride from the Bronze age to this 3000 years later
