Additional evidence is presented and discussed on the mechanism for the subthreshold leakage currents induced in power MOSFETs by single nucleon and ion interactions. The new evidence excludes microdose in gate oxides and instead points to microdose

During neutron irradiation of 4-Mb SRAMs, large-scale multiple cell upsets (MCUs) were observed. These were observed in 90-nm devices at accelerated test facilities providing fission, fusion, and spallation neutron environments. The MCUs are shown to
