Radiation hardened

Physical
Use of a special process node provides increased radiation resistance. Due to the high development costs of new radiation hardened processes, the smallest "true" rad-hard (RHBP, rad-hard by process) process is 150 nm as of 2016, however, rad-hard 65 nm FPGAs were available that used some of the techniques used in "true" rad-hard processes (RHBD, rad-hard by design). As of 2019 110 nm rad-hard processes are available.
