    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.
