  • Abstract
    In this study, a capping layer was deposited after CMP polish when finish the SiO2 layer. These interrelated problems can be solved with a proper fabrication process strategy. This effective strategy will eliminate copper extrusion using in many semiconductor processes. Stronger interface reduce the diffusion of Cu through IMD.
