Summary :

A new technique for evaluating gate oxide reliability using photon emission method has been developed. This method enables the measurements of the initial breakdown characteristics, reliability testing and failure analysis consistently. From the experimental results, followings are clarified for the first time using this technique. Failure modes in the initial characteristics have close correlation to TDDB characteristics and both characteristics correspond to the location of breakdown spot. The results suggest measures to improve the reliability of gate oxide and the existance of new failure mechanism.
