Did he do his own etching? I'd say buying blank wafers would be a perfectly reasonable place to start, but if you're buying printed wafers, then you might as well buy the whole chip.
- grenoire 5y agoYeah, I don't think people will be pulling pure silicon crystals at home any time soon.
- Aeolun 5y agoIf they do, I imagine they’d leave it at that instead of going on to make a chip.
- wrycoder 5y agoThat’s actually quite doable in a garage, assuming you are satisfied with, say, two inch wafers. (Currently, they are approaching 18 inches!) It’s much easier to produce silicon ingots than to do wafer fab, because of the currently tiny line widths. But, it would make more sense to simply buy wafers (or epitaxial wafers).
- ip26 5y agoI believe he bought them with the gates etched & fets doped, and did his own metal. Something like that.
