Hard for me to read the level of hyperbole here, but does that mean it’s something that could conceivably be manufactured in a home?

- mjevans 6y ago40nM is about 13 years old at this point, and has been replaced superseded several times. https://en.wikichip.org/wiki/40_nm_lithography_process https://en.wikichip.org/wiki/40_nm_lithography_process Probably the only reason that line is still running would be validated long term stability products, or niche hardware designed with special application compatibility (E.G. radhard, higher end mil / aerospace concerns, maybe automotive). Semiconductor tooling is rather expensive and I imagine that updating this to a more modern line would require overhauling and re-balancing many systems. It might help someone not familiar with the industry to imagine each technology node as an entirely new model of car.

- samus 6y agoThere are some projects where people try to etch silicon in their garage, but the node they are targetting is from last century. Anything newer and you need toxic and corrosive chemicals, and increasingly exotic equipment. The yield isn't great either.
