Abstract :
The conduction and trapping phenomena in very thin (100 Å) thermally grown films of SiO2have been studied and their dependences on temperature have been determined from room temperature to 200 °C. The results of constant current injection trapping studies indicated that the total breakdown charge density decreases approximately linearly with the logarithm of injection current density, J . The total breakdown charge density showed an Arrhenius behavior with temperature and a single activation energy of 0.155 eV was obtained for J = 0.278 A/cm2. The mean breakdown voltage obtained from time dependent electrical breakdown experiments was independent of temperature for a constant J . However, at room temperature the mean breakdown voltage showed a tendency to increase with increasing J .
