Radiation tolerance goes down with node size. Companies aren't pushing much smaller because they there's nothing they can do about the increased upset rates at those sizes. Rather, they're turning to other options to achieve rad tolerance in critical systems, stuff like soft cores specifically designed for redundancy running on radiation hardened FPGAs. Also, the rad tolerant parts aren't there to do the crazy high speed work. When people talk about voting architectures with redundant COTS parts, what do you think is counting the votes and resetting the effected systems?
