Web12 mei 2024 · Total Ionizing Dose Effects on MOSFET and BJT When radiation is injected into a metal-oxide semiconductor field effect transistor (MOSFET) and bipolar junction transistor (BJT), electron hole pairs (EHP) are formed along most of the radiation path, including the oxide layer. WebIonizing radiation effects in MOS devices produce shifts in the device characteristics. These shifts depend on the radiation doses and also on the gate oxide bias during irradiation. This bias effect makes it difficult to predict radiation effects on operating MOS LSI's, because bias conditions are generally not constant. It is, however, important to …
