This 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 art chips take 3-4 months to complete this process and it's well over a thousand steps.

In some cases yes, in others no. As much as I love my new electronics I still play my 14 year old Xbox One, read on my 2012 Kindle Paperwhite and use multiple 5+ year old laptops that function almost the same as they did (running Linux helps). 3 years is not really the lifetime of most consumer electronics anymore...at least outside of the latest GPUs.

The latest GPUs will also be functional for longer than 3 years. They may or may not still be economically efficient for LLM companies to operate.

I think the chosen visualization detracts from learning rather than enhancing it. A simple, static flowchart would be more informative, easier to consume, and almost certainly less buggy and confusing to interact with.
- Good info from reputed sources gets an A, non reputed gets B
- Opinion blogs are at the bottom of the barrel and maybe ranked C, D, E and even F depending on quality
- it is explained in the link too

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.
trashb 18 minutes ago [-]
I always thought it came from the Japanese school rating system, where the concept was transferred to the west through the medium of games. I was under the impression that this system preceded the creation of video games but I can not find a reference for that.
In Japan the "S" is explained as shū (秀) "Exemplary, excellent".
At the end the truckload of chips should be happily on its way to a consumer electronics factory when it gets suddenly diverted along with all the others down a side road that dumps all the chips into the ravenous insatiable maw of the hyperscale datacenter industry.

Running 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

Nice website. One problem, though: the animation goes too fast for my reading speed, so I have to click stop. Then when I click on the next thing, I have to click stop again. Very annoying. If I click stop, just make it stay stopped until I click play again (which I won't).

First time I’ve seen a lithography machine referred to as “a printer”. Is that really what they call it in fabs?
HPsquared 3 hours ago [-]
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.
inigyou 2 hours ago [-]
AIUI it does step,expose,step,expose,step,expose,...
skrebbel 19 minutes ago [-]
The newer machines don’t step but scan.
laurentiurad 4 hours ago [-]
It's meant for people that do not have extensive knowledge over how chips are made. I doubt majority of the people know what lithography means, let alone DUV EUV etc.

Here's a video in case anyone else is also curious about what the crystal puller part looks like:
Cute, 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.
laurentiurad 3 hours ago [-]
Why is it wrong? Asking as I am keen to correct it
q3k 2 hours ago [-]
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.
laurentiurad 1 hours ago [-]
Yet you didn't say what is wrong. What is the purpose of your comment? Might not be photographed but projected through a photomask. Does it change the semantics? No. This is not a guide for developing a fab, just to be clear.
q3k 1 hours ago [-]
I told you - it's not the correct term. Finding the correct one should be something you can achieve in 5 minutes of research, and then you can confirm your understanding with a SME.
To be clear, I am also not an expert - I can pick out things that are wrong because I generally know a thing or two about semiconductor fabrication, but I'm not willing to sign-off on correctness of the whole thing, especially wrt. to modern processes. I personally wouldn't publish anything about this matter without getting it checked by someone else, because I know where the limits of my knowledge are.
The goal of my comment was to bring that to your attention - that you need someone to actually review your content before you continue teaching people the wrong thing. When you're educating people, you're in a position of power that comes with the responsibility of making sure what you write is as correct and clear as possible. You have a duty of care.
laurentiurad 1 hours ago [-]
So you posted a comment, then refused to give details because I can do it myself "in 5 minutes of research"? Like I said previously, this is not meant to be sent to TSMC so they know what to do when opening their new fab in Arizona.
rcxdude 19 minutes ago [-]
The point is that it's not a credible resource, and one or two point corrections from randos who can see some of the errors are not likely to change that.

AI generated or not, the target device was the PC, but the point still stands. Anyway, you have a pause button that you can click to pause the flow. On PC you might not use the mouse that extensively so pressing Space saves time. It's just a nitpick that I haven't removed the Space reference on mobile, but you can still pause the flow.

I created Chip Tycoon as an animated visualization of the semiconductor manufacturing process, inspired by the classic isometric style of RollerCoaster Tycoon and Zoo Tycoon.
Rather than reading through a long article, you can watch silicon move through the major manufacturing stages—from wafer fabrication and lithography to packaging and testing—in a miniature factory.
My goal was to make one of the world's most complex manufacturing processes easier to understand by turning it into something that feels alive and enjoyable to watch.
mcphage 16 hours ago [-]
It's neat, but I'm not entirely sure what the animations contribute. What's neat about games like RollerCoaster Tycoon is watching this entire map full of things happening without needing to be controlled, but this doesn't really have that. There's your vehicle moving around, and there's people wandering around, but they're not doing anything. It doesn't feel like a factory of connected components.

I thought it was cute.
The RCT style didn't really add anything other than showing it on a conveyor belt of sorts, but it was cute and in a world where HTML and CSS are practically free to make, we might as well spend some tokens on making educational content a bit more digestible.
I'm sure there's a plaintext essay that can explain this just as well if the RCT style was distracting.

Mission achieved: It's cute.
Some feedback on the UI. Just knowing there was an automatic timer made me feel rushed while reading each expanded step (regardless of speed selected), so I tried to manually take over the navigation, by using the pause button, next step button, and tapping factories. This caused my conveyor cart to somehow become decoupled from the current step and felt kind of buggy.
I also felt trapped in the Loop, which went around 3 times. I didn't notice an exit button. Better yet, this is a transition where perhaps a swift animation of the cart going around a few times on its way to the next step may help communicate the sense of repetitiveness you're trying to make the user feel.
I was on mobile and I noticed by the end of the park my phone had gotten quite noticeably hot - which is unusual except when under heavy gaming load.
Thanks for putting this together. Ironically, I found your concise and frank little written synopsis at each step the most interesting part.
bluezly 8 hours ago [-]
I had the same feeling. I think it would click more if the cart visibly changed after each station — add a layer, change color, get cut into dies, etc.
Then the animation would be doing some of the explaining instead of mostly being scenery.
