Bah, I could setup a large format camera and do optical reduction of an arbitrary B&W image, transfer that image onto a semi-conductor with a laser, then deposit a thin layers of metal (and whatever) onto it in a vacuum chamber for like, maybe $5 of material. What a ripoff.
- shrubble 6y agoYou can in fact do this. The process for the original 6502 chip is publicly available I think. You could make it even smaller than the original 8um, probably.
- javajosh 6y agoI know its possible, I was only being 25% facetious (which is presumably why someone downvoted me). FWIW in all seriousness, getting anything non-trivial to work at 8um would be VERY impressive in a garage-level environment, and of course you'd still be off world-class fabs by 3 OOM!
- jsjohnst 6y agoThen go show the leading world manufacturer how it’s done by opening your own fab and turning out billions of chips. Even with 100,000% markup from your $5 cost basis, you’ll have customers lined up for the next decade if you could really pull it off. We won’t hold our breath waiting to hear back on your success... ;)
