Reliability of electronic devices has been an issue of serious importance. One of the potential factors to spoil the reliability is possible local drops of strength on the interface of multilayered structure. A new technique for the evaluation of local interface adhesion energy was applied to the interface between Cu and cap layer in a Cu damascene interconnect structure, in order to elucidate variation in adhesion strength as a function of measurement location.
