F. Seigneur et al., EFFECT OF (CO)-C-60 IRRADIATION AND FOWLER-NORDHEIM INJECTION ON MOS CAPACITORS WITH THIN PLASMA-NITRIDED GATE OXIDES, Microelectronic engineering, 28(1-4), 1995, pp. 345-348
We have investigated the generation of interface traps during Co-60 ir
radiation and Fowler-Nordheim (FN) injection in MOS structures with th
in plasma nitrided gate oxides. By using deep level transient spectros
copy and capacitance-voltage measurements, we have studied the impact
of nitridation time on the creation of fast and slow states in the sil
icon bandgap. After FN injection, electrical relaxation of the interfa
ce has been interpreted as the superposition of two mechanisms : an ir
reversible physico-chemical time-dependent transformation and a revers
ible bias-dependent neutralization
