I am quite surprised to hear that. Really?
- os2warpman 1y agoYup! Here's one in Utah: https://www.nanofab.utah.edu/ https://www.nanofab.utah.edu/ Here's one in Pennsylvania: https://www.mri.psu.edu/nanofabrication-lab https://www.mri.psu.edu/nanofabrication-lab Here's one in California: https://nanofab.ucsb.edu/ https://nanofab.ucsb.edu/
- BenjiWiebe 1y agoThose aren't starting from sand though, so they do need some external fancy tech to survive the apocalypse - to produce their wafers.
- packetlost 1y agoIt won't be small, but you can create PCBs pretty easily with chemical etching. I think making the silicon wafers is probably harder.
- ummonk 1y agoPCBs are something people can do in their garage. Integrated circuit fabrication is definitely something that requires a much more sophisticated lab such as a top university lab.
- guhidalg 1y agoDepends on the state, but for my alma mater (Georgia Tech) I'm pretty confident the answer is yes.
- os2warpman 1y agoGeorgia Tech has one of the best fabrication programs in the world.
- cycomanic 1y agoI just had a look and I am not sure they are making silicon wafers. I would be surprised, there's not really any research in it, and it's costly to say the least.
- ummonk 1y agoYeah, I find that rather surprising that a university lab could fabricate a practical 14 nm chip (more than just some demonstration gates), given the billions of dollars that countries have to invest to set up even 65 nm fabs.
