A good scanning electron microscope costs at most a few million? And is pretty common in a decently funded lab pretty much anywhere? Resolutions of 5nm is not uncommon. A scanning tunnelling microscope can go much lower (single atom types) and isn’t all that much more expensive either (comparatively I mean).
I think it’s common knowledge by now that the smallest feature in a 5nm chip isn’t really 5nm. So that’s not (yet?) a viable strategy.
You mean you’d rather run unverified scripts using a good order of magnitude more resources with a slower experience and have an entire sandboxing contraption to keep said unverified scripts from doing anything to your machine…
I know the browser is convenient, but frankly, its been a horror show of resource usage and vulnerabilities and pathetic performance
The #1 reason the web experience universally sucks today is because companies add an absurd amount of third-party code on their pages for tracking, advertisement, spying on you or whatever non-essential purpose. That, plus an excessive/unnecessary amount of visual decoration.
The idea that somehow those companies would respect your privacy were they running a native app is extremely naive.
We can already see this problem on video games, where copy protection became resource-heavy enough to cause performance issues.
As one of those on the skeptical side, one train of thought I have not seen people even mention is, the way we’re using LLMs to code now is largely to use a less precise language (mostly English) to specify what’s often a very precise problem and solution. Why would we think that spoken language is the best interface for doing this?
I've actually found the opposite, it's easier to conceptually understand the continuous FT, then analyze the DTFT, DFT, and Fourier Series as special cases of applying a {periodic summation, discrete sampling} operator before the FT.
They already do offer that - it’s called a multi-project wafer or MPW. But it’s prohibitively expensive on a per-chip basis. It’s mostly used for prototyping or concept proving and not for commercial use.
One problem is, you need to create a photolithography mask set for any volume size of fabrication and those aren’t cheap. But that’s far from the _only_ problem with small volume.
Finicky chemicals and relatively expensive equipment. But he’s founded a company with Jim Keller. We occasionally see them post a photo with zero context, but we do know some things. Like they are targeting lots volume stuff and basically building fab equipment. But not much more.
If stored in proper conditions, the shelf life of undiced wafers is pretty much limitless. But if moisture or dust get in, it’ll start to have corrosion and other damage. Diced wafers on the other hand are placed on UV tape and I recently learnt that the shelf life of that is like a few months at best.
Nevertheless, unless you’re not storing them in a clean room of appropriate class (or in a vacuum pack), assume 18 months for undiced wafers.
In terms of size, I would think that stored in cassettes or carriers a vacuum sealed, it shouldn’t be too much. A 25 wafer pack is about half meter cube? A 40ft shipping container is about 68m^3. So one container can store about 140 packs of 25 wafers each. That’s 3500 wafers. They’re talking about 900k wafers. That’s about 260 containers. Call it 300 with extra space and stuff. Not exactly hard to provision.
