Abstract

The effect of 30 MeV Li³⁺ ion and 8 MeV electron irradiation on the threshold voltage (V_TH), the voltage shift due to interface trapped charge (ΔV_Nit), the voltage shift due to oxide trapped charge (ΔF_Not), the density of interface trapped charge (ΔV_it), the density of oxide trapped charge (ΔN _ot) and the drain saturation current (I_{D Sat}) were studied as a function of fluence. Considerable increase in ΔN_it and ΔN_ot, and decrease in V_TH and I_{D Sat} were observed in both types of irradiation. The observed difference in the properties of Li³⁺ ion and electron irradiated MOSFETs are interpreted on the basis of energy loss process associated with the type of radiation. The study showed that the 30 MeV Li³⁺ ion irradiation produce more damage when compared to the 8 MeV electron irradiation because of the higher electronic energy loss value. High temperature annealing studies showed that trapped charge generated during ion and electron irradiation was annealed out at 500°C.
