Abstract :
Charge pumping measurements show the so-called ´enhanced´ degradation under alternating stress conditions, as concluded before on the basis of threshold-voltage (or transconductance) shifts only, can be totally explained by the masking of interface traps by channel shortening and compensation of trapped charge during the degradation.<>
