THE VIDEO SHELF · EUV lithography
The Extreme Engineering of ASML’s EUV Light Source
Asianometry explains the EUV light source inside ASML's lithography machines, where lasers hit falling tin droplets twice to produce 13.5 nm light. It walks through the engineering of the droplet generator, the pre-pulse and main laser, and the plasma that results.
Why HN readers recommended it
Commenters repeatedly point to it whenever EUV, ASML or chip manufacturing comes up, as a clear and astonishing explanation of one of the hardest engineering problems in chipmaking.

Because the EUV machines that ASML build are the most complex machines ever built by humans and getting all the bits to work properly takes decades of R+D e.g. watch this about the light source, its completely bonkers [VIDEO]

In Two startups tried to catch up to makers of advanced computer chips, and failedEUV lithography is interesting. You drop a microscopic droplet of tin. You then aim and shoot it not once, but twice with a laser so it produces the correct wavelength. Then you do this with 100% reliability thousands of times per second all day, every …

In Fusion “Breakthrough” Won’t Lead to Practical Fusion EnergyAnyone interested in the details should watch this video: [VIDEO] (has the same graphics) without any hyperbole the 2-shot laser thing necessary to emit EUV is just mind bending.
