Abstract
Dielectric composite structures comprising interfaces possessing nanometer scale corrugated interfaces in interconnect stack provide enhances adhesion strength and interfacial fracture toughness. Composite structures further comprising corrugated adhesion promoter layers to further increase intrinsic interfacial adhesion are also described. Methods to form the nanometer scale corrugated interfaces for enabling these structures using self assembling polymer systems and pattern transfer process are also described.
