1. Build a quartz crucible inside an inert argon atmosphere
2. Heat it to 2600F/1400C
3. Melt your highly pure silicon in it
4. Add in a seed at the top that the rest of the silicon can crystalize around
5. Now comes the tricky part that requires some experimentation: Pull out the seed very carefully while rotating it, so that an ingot forms around it as you keep pulling
I genuinely think that was one of the more amusing exchanges I found on HN. There is just such a weird level of.. it could very well be a deadpan joke, but also a well-meaning, helpful response.
This made me realize that I don't mind humor in HN comments when they're genuinely clever.
This is opposed to what you often see on Reddit where the "funny" comments are just chains of some meme/common phrase and display no ingenuity (though, to be fair, I did once find those comments funny).
Well, clearly your first problem is that you want it to be that large in the first place. 30cm ought to be enough for everyone, if it's good enough for TSMC it's good enough you.
Everyone knows TSMC can't make the newest AI chips that have to multiply a 1,000,000,000x1,000,000,000 matrix every clock cycle. What if you're trying to compete with Nvidia?
