Vs. Pershenkov et al., THE EFFECT OF EMITTER JUNCTION BIAS ON THE LOW DOSE-RATE RADIATION RESPONSE OF BIPOLAR-DEVICES, IEEE transactions on nuclear science, 44(6), 1997, pp. 1840-1848
It is shown that emitter-base junction bias is significant for low dos
e rate irradiation response of npn and pnp bipolar transistors. The ef
fect is more pronounced for pnp transistor. Experimental results are e
xplained in terms of fringing electric field model. The role of fringi
ng field is confirmed by the radiation induced charge neutralization e
xperiment. The experimental results on the effect of emitter junction
bias on the elevated temperature high dose rate irradiation of bipolar
devices and its application for low dose rate response simulation are
discussed.
