#42Running a chip fab would actually make a pretty good Factorio-style automation game with perhaps puzzle elements inside the lithography device and in the tape out portion
I am on it

great video!
Re: Learn how chips are made with this Rollercoaster Tycoon-inspired animation
#44Cute, but the steps don't make sense. E.g. each cycle shows both an ion gun and wire deposition. But only the first layer would use the ion gun, and only the following layers would have metal deposited. (Front End of Line vs Back End of Line). Not to mention the lack of diffusion and oxidation. The whole "loop" metaphor gives the wrong idea of what's happening.
Also "The pattern is photographed onto the wafer."... shudder. All subtly wrong. And no, not in the 'simplified' sense.
Why is it wrong? Asking as I am keen to correct it

#45This is pretty good...simplifies the process and some of the items are out of order, but it describes the process pretty well. Keep in mind, even 20 year old chips have 6-700 steps in their process...it's a giant loop of Etch, Photo, Implantation, Furnace, Chemical Vapor Deposition, Physical Vapor Deposition, Chemical Mechanical Planarization, etc...don't forget the measurement steps and defect scans. State of the ar…
Months?! Wow, I had no idea. So it's a very long pipeline.

#46Earlier quoted context omitted.
How does S compare to F if F is the bottom-of-the-barrel worst? Or does it just stand for slop? Your link doesn’t mention it anywhere
S-tier comes from games. An A to F scale with S representing a "super" or "superior" rating has been around in that space quite a bit longer than LLMs.
- it also comes from one punch man
- the greatest heroes are in the S-Tier
- A ranking heroes are the second best
- Then B, C, D, E, F....

#47First time I’ve seen a lithography machine referred to as “a printer”. Is that really what they call it in fabs?
I hear the word "stepper" used sometimes talking about lithography machines. Makes sense I suppose that you'd need to precisely move the wafer around and expose small parts of it.

#48this was pleasantly instructive, thanks for sharing!

Because it's not the correct term. And that's not the only thing that's wrong, see the parent comment.
With all due respect, I would recommend you run any educational resources and infographics you create past an actual subject matter expert (not an LLM!) before release. Otherwise you're just spreading shiny misinformation.

I am taking notes about how to make chips in my garage.
