Experimental procedure influence on total dose CMOS inverters hardness

This issue deals with Co60 irradiation results on three commercial CMOS inverters. About ten years ago, it was proved that this type of "soft oxide" component could undergo rebound effect although only rad-hard NMOS was concerned. The work presented here takes into account dose rate (tested over 5 decades) and bias effects. The results of prediction with linear system theory are compared with experimental tests and discussed. Post-irradiation behavior with temperature may be very useful to understand long term evolution and so, can lead us to an explanation of linear system limitations in different cases.<
