Abstract
Silicon MOS structures with an SiO2−Si3N4 insulator were exposed to X-rays. Positive oxide charges arise and the continuous density of fast states increases at the Si−SiO2 interface. In addition, a single energy state develops above the middle of the energy gap atE−E v=600 meV. Annealing measurements in dry air and H2 lead to the conclusion that the single energy level originates from a dissociated hydrogen bond in the silicon dioxide.
