Abstract :
The effect of time-dependent stress voltage and temperature on the reliability of thin SiO2 films is incorporated in a quantitative defect-induced breakdown model. Based on this model, design curves which can be used along with a breakdown voltage distribution for an oxide technology to determine optimal burn-in conditions are presented. The tradeoff between improved reliability and lower burn-in yield for different gate oxide technologies can also be examined quantitatively using the model
