Abstract :
Interfacial characterization of ultra low-k film with the layer underneath is very important for reliable manufacturing of ultra low-k film. In this study, we proposed a new application of TOF-SIMS to predict the interfacial behavior of the ultra low-k with the layer underneath. Strong correlation between carbon intensity at the bottom interface with the adhesion energy of the ultra low-k with the layer underneath is observed. We also observed a linear correlation between the quantified carbon peak intensity and the adhesion energy.
