D. Zupac et al., SEPARATION OF EFFECTS OF OXIDE-TRAPPED CHARGE AND INTERFACE-TRAPPED CHARGE ON MOBILITY IN IRRADIATED POWER MOSFETS, IEEE transactions on nuclear science, 40(6), 1993, pp. 1307-1315
An effective approach to separating the effects of oxide-trapped charg
e and interface-trapped charge on mobility degradation in irradiated M
OSFETs is demonstrated. It is based on analyzing mobility data sets wh
ich have different functional relationships between the radiation-indu
ced oxide-trapped charge and interface-trapped charge; Separation of e
ffects of oxide-trapped charge and interface-trapped charge is possibl
e only if these two trapped charge components are not linearly depende
nt. A significant contribution of oxide-trapped charge to mobility deg
radation is demonstrated add quantified.
