Ionizing radiation effects in mos oxides
Web1 mei 2024 · Scaling down in CMOS technologies shifted modern integrated circuits towards the reduction of the gate oxide thickness of MOSFETs. This trend is the main factor that made transistors of advanced technologies more tolerant to ionizing radiation (Derbenwick and Gregory, 1975; Viswanathan and Maserjian, 1976). WebIonizing radiation can induce significant charge buildup in these oxides and insulators leading to device degradation and failure. Electrons and protons in space can lead to radiation-induced total-dose effects. The two primary types of radiation-induced charge …

Webfrom the Fig. 1, ionizing radiation can degrade CMOS sensor pixel performances by changing the characteristics of the “in-pixel” MOSFETs, the photodiode and/or the STI oxide. In fact ionizing radiation is known to generate trapped charge and interface states in MOS oxides. These can lead to voltage shifts and current Web1 jan. 2009 · Abstract Based on the physical process of holes trapped in oxide and interface trap buildup induced by proton, a unified physics-based model of oxide-trapped charge …
Web1 feb. 2014 · The positive oxide charge buildup and interface trap generation by γ-ray irradiation in MOS structures have been investigated as a function of gate oxide quality, … 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 …
