摘要
A correlation between channel hot-carrier induced degradation in conventional-drain NMOSFETS and radiation-induced transconductance, gm, degradation is described. The device lifetime, τHE, after hot-carrier stressing was found to be τHE = A D1.5EFF, where DEFF is the radiation dose when Δgm/gm = 0.5. These results indicate that radiation-induced interface trapping is a strong indicator of hot-electron device lifetime. The proposed radiation test can be applied to devices with both radiation-hard or radiation-soft field oxides.
