  1. Well the "two light cones overlap by 1°" means the the next mirrors (before and after the mask) would have to physically overlap. That's not possible - you can't have two things in the same place. Jon's graphics here is not accurate, he should draw actually overlapping cones instead of keeping the same cone and just putting the word "overlap" there.

  2. Sounds like a Hail Mary to me ("We didn't yet master the process but let's build 4 factories based on that process instead of one. The engineers will figure it out.")

  3. Maybe they were trying to follow the "fail early, fail fast" mantra

  4. $9.6M in cash and stock? These are rookie numbers, says Mr. Musk.

  5. I hadn't considered the "Nvidia taking control of the driver" as explicit as you said it. In fact, I suspect by doing that they helped all their card OEM customers taking away the burden to write and keep up to date their drivers.

  6. I know an innovative Finnish software company, named M-Files Oy based in Tampere. They moved their HQ to USA not long ago - probably because access to VC money and developers is better there. In fact, they recently announced another funding round led by a US VC. But Finnish people still run most of the show.

  7. The more x-ray the radiation the less it interacts with surface material (your photoresist). So it will require even higher optical power to run a litho process. Also the optical path will become very elongated (vs. folded in a compact space) as mirrors have to have very low angle of incidence, as previous poster mentioned. Basically like synchrotron beamlines.

  9. Trumpf make the drive laser, for example - that is a well-known fact and you can even find videos about it here on YT. Every hardware company buys from suppliers and often they don't want to disclose who these valuable suppliers are.

  10. Great videos! Can you make videos about other Taiwanese electronics manufacturers, like Gigabyte, ASUS, MSI etc. ?

  11.  @dwliu6582  I suggest you make a video on semicon fab construction - let us enjoy your wisdom. We may even subscribe to your channel

  12. Bring it on, I want cheap chips! Basically I'm holding out since months to get a new Ryzen based setup.

  13. This is a dangerous question because ferromagentism ("magnets") is down to quantum mechanics. Not simple quantum mechanics but a collective effect of many ferromagnetic atoms.

  14. For a material to exhibit ferromagnetism (i.e. what we call a permanent magnet) you need a certain number of atoms - too small and it won't stay magnetized. Also there are issues with switching the magnetization fast enough. Now you could envision to use a SINGLE atom's spin to store (or manipulate) information - this is called spintronics. But there are challenges to make it reliable enough as there needs to be very good isolation for surrounding environment. Spintronics is an ongoing research topic - would actually be interesting for Asionometry to cover it. It's a little bit like fusion power is for energy: the elusive holy grail of miniaturization.

  15. NA 0.55 in vacuum is about 33° half-angle or 66° full angle of the light cone. (NA = n * sin alpha, where n=1 (vacuum) and alpha is the half-angle).

  16. B2B and B2C distribution are very different beasts. SGI may well have been capable of solving the technical challenge but then there is the go-to-market strategy that has to match the customer. Jon gave us right in this video the example of how you can fail with 3dfx trying to go from B2B (selling chips to gfx card makers) to B2C (selling finished cards to consumers). Fail you will if not prepared for differences in sales and marketing approach.

  17. Mo/Si multilayer mirrors, same as within the ASML machine

  18. Well Americans hold critical IP and as soon as you have a US-sourced part in your machine it becomes subject to US export control. The ASML "source" comes from a US-subsidiary (ex Cymer) so it's not like ASML has a lot of choice.

  19. So masks with damaged pellicle were sent for repair?

  20. What do you mean by "stack them up"? The light has to go from one mirror to the next, so you have to zig zag somehow. Moreover, the angle of incidence (at what angle the light bounce off the mirror) has to be within a certain range for the multilayer to work properly.

  21. Bro, have you heard of the BBC Micro, ZX Spectrum, Acron Archimedes, ARM and there is a bunch of good UK computer game studios on the software side.

  22.  @ArtificialDjDAGX  Diamond has the best heat conductivity of any material, also very good insulator (if pure), see Thermal Conductivity chapter on Wikipedia: https://en.wikipedia.org/wiki/Material_properties_of_diamond

  23. Very nice. Maybe you can do an aerial drone video next time - if it is allowed?

  24. That is not the entire machine. There is another bus-sized laser situated in the basement floor and then there are cabinets of power-supplies. The driving laser is made by Trumpf - maybe you have even worked with one of their other machines. https://youtu.be/OK19DoPA8vc
