摘要

To support space applications we have produced arntest chip with our in house 0.25 micron BiCMOSTechnology.rnThen the chips were radiated andrnmeasured. During measurements no thresholdrnvoltage shift and no single event latchup (SEL) werernobtained up to a level of 200 krad. As conclusion ofrnthe measurement we developed new radiation hardrndesign rules and according to these rules we createdrna new radiation hard CMOS library. With this newrnlibrary we produced a Leon3 chip with triplernmodule redundancy. Single event upsets did occur.rnTherefore we upgrade the library to make the fliprnflops more resistant against single event upsetrn(SEU) by adding two p-MOS transistors.
