There is a third thing, which is to use a dopant which reduces minority carrier lifetime and provides radiation resistance when manufacturing the semi-conductor. Platinum works really well for this. Unfortunately, this can be a poor engineering tradeoff for some kinds of electronics (power transistors for example) and usually increases electrical resistance. AFAIK nobody manufactures platinum-doped microprocessors. I used to be a product manager for radiation measurement electronics, and we used platinum-doped diodes for the part intended to go in the beam. See for example:
