Charge accumulation in an MNOS structure with carrier injection from the field electrode
The authors propose a method for determining the parameters of trapping centers by injecting electrons into the insulator of an MIS structure from the field electrode, when a negative voltage pulse with amplitude U and duration t is applied to it. The results indicate that in silicon nitride, just as in silicon oxide, degradation is apparently caused by the trapping of holes in traps formed by Si-H bonds. The trapping of a hole stimulates the breaking of the bond and the appearance of a mobile H/sup +/ ion. In this case, the mobile H/sup +/ ions, appearing as a result of the flow of the hole current, passivate the incomplete bonds of the silicon atoms and thereby decrease the concentration of electron-trapping centers.
