Abstract
In this paper, techniques to measure reliability of inter-line dielectrics (both SiO2 and SiOC) in copper dual damascene structures are described. The failure times for tests of single damascene structures were found to vary by many orders of magnitude depending on the process. A voltage ramp test for inter-line reliability is proposed that is better able to capture the wide range in reliability that can results from process variations in a dual damascene process flow
