Ch. Ling et al., SPATIALLY UNIFORM DEGRADATION IN NMOSFETS - EVIDENCE FROM GATE CAPACITANCE AND CHARGE-PUMPING CURRENT, Electronics Letters, 30(20), 1994, pp. 1720-1722
A linear relationship is found to exist between the decrease in the ga
te-to-drain capacitance with stress time and the corresponding increas
e in charge pumping current, in hot-electron stressed nMOSFETs. The re
sult supports a spatially uniform degradation at the Si/SiO2 interface
, that starts within the LDD junction and progresses into the channel.
