E. Bendada et al., DIODE IDEALITY FACTOR FOR MOSFETS CHARACTERIZATION OF DOSE-EFFECT, Radiation effects and defects in solids, 138(1-2), 1996, pp. 39-48
An innovative method for device characterization is developed to quali
fy radiation effects. A study of radiation induced effects on carrier
transport phenomena has been carried out on the body-drain junction of
power HEXFETs. A large increase of the recombination current is point
ed out. The degradation, by ionizing radiation of the junction idealit
y factor is shown to be controlled by the total dose. These effects ar
e discussed and related to the oxide-semiconductor interface potential
