Processor Production - Can old chips be produced again?

[Musashi]

Per the title: If a processor is taken out of production, is putting it back into production prohibitively expensive? Or could a smaller version of an older chip be reinstated cheaply using more efficient process size we have today? Or is the answer something in the middle?

I found one guy claiming that Nintendo is facing backlash from their manufacturers due to the old age of the Switch's main board. Is there something to what he's saying or no?

short answer yes realistic answer no, its extremely expensive due to the clean room environment required. Nintendo needs to upgrade the chips on the motherboard plain and simple
