They where using TSMC fabs, but obviously that's no longer the case. Russia currently don't have fab that goes beyond 90nm (https://en.wikipedia.org/wiki/Mikron_Group https://en.wikipedia.org/wiki/Mikron_Group). There where plans to go to 28nm in 2030, but without access to western technologi that's not happening. The latest Elbrus is 28nm, so my guess is that they aren't made at all right now. Edit: The latest Elbrus chip that Russia can fab appears to be the Elbrus-2SМ, which is a 300MHz processor. https://en.wikipedia.org/wiki/Elbrus-2S%2B https://en.wikipedia.org/wiki/Elbrus-2S%2B
