Nearly the same decrease was observed during proton irradiations of 9/spl times/10/sup 12/ cm/sup -2/. But after a neutron fluence of 1.5/spl times/10/sup 13/ cm/sup -2/ the signal was still 85% of that before irradiation. It is shown that the decrease of the photocurrent is caused by darkening of the glass window. Some of the color-centres could be annealed with the intense UV-light of a deuterium lamp. Furthermore hydrogen treatment of the photodiode reduces the radiation effects by about 20%.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.

Closed-geometry and standard transistors fabricated in two fully-depleted processes were irradiated with 10-keV x rays. Our results show that increases in radiation-induced leakage current are caused by positive charge trapping in the buried oxide inverting the back-channel interface. At moderate levels of trapped charge, the back-channel interface is slightly inverted causing a small leakage current to flow. This leakage current may be amplified to considerably higher levels by impact ionization. At high levels of trapped charge, the back-channel interface is fully inverted and the gate bias has little effect on leakage current. Large increases in leakage currents can be obtained with or without impact ionization occurring in the channel region. For these transistors, the worst-case bias configuration was determined to be the \"ON\" bias configuration for both the cases where radiation-induced transistor response was dominated by charge buildup in the buried oxide and in the trench sidewall isolation. These results have important implications on hardness assurance.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.
