The effects of low temperature ([le]700 [degree]C ) annealing on the thermal dissociation of hydrogen-passivated interface trap centers of a SiO[sub 2]-Si(100) system is studied using positron annihilation spectroscopy. The Si---H bonds dissociate with an activation energy of 2.60[plus minus]0.06 eV. Assuming that the anneal generates trap centers with a single charge, positron measurements indicate that [similar to]4.5[times]10[sup 8] trap centers/cm[sup 2] are created by a 600 [degree]C anneal.
