    Abstract: This invention provides a dual damascene structure having capacitors. Before the thin-film capacitor is formed, the underlie interconnections are fabricated with Cu metal by damascene processes. The capacitor is formed by depositing a first metal layer, an insulator and a second metal layer. Then, the stacked layers are subjected to two masking and etching processes to form the thin-film capacitor and the metal wire. After forming the capacitor, the upper interconnections are fabricated with Cu metal by damascene processes.

    Abstract: An organic copper diffusion barrier layer having low dielectric constant is provided. The organic copper diffusion barrier layer can be applied to a dual damascene structure, which is formed between a copper wiring layer and an organic dielectric layer, to defend copper diffusion from the copper wiring layer into the organic dielectric layer. The organic copper diffusion barrier layer includes a benzocyclo polymer, which it has a benzene ring functional group that can catch copper and prevent copper diffusing into the organic dielectric layer. The problem of thermal diffusion and electro-migration can be avoided.
