14nm is mature and would suit this purpose fine, and they have existing capacity. The business, tools, and everything else around would need to get built out.
Yes. But Intel doesn’t have any customers and do they even have 14nm fabs online and how long will take to move customers to it in the case of a disruption?
To have customers they need to do the actual work of closing deals, building the customer-facing support teams, building all the tooling integrations (PDK, simulation, etc). On the manufacturing side they have to figure out who will do all the stuff besides fab, I think they have 14nm currently in the US and Ireland but the packaging might all still be Asia. It's not something to be done in case of disruption, it's essentially starting 80% of a new company to serve customers who want a US and Europe based supplier. Government customers could work, or public/private joint venture to build commodity parts, but either way they need patient customers who can help work out the problems and pay a premium to do it.
