Abstract: PURPOSE: A method for forming copper wiring of semiconductor device is provided to progress a dual damascene process without chemical mechanical polishing suing copper electroplating and copper electro polishing. CONSTITUTION: An inter-level dielectric layer(3) is created on a substrate(1) covered with a conductive film(2) and a via(contact) hoe(4) and a trench(5) is formed in the inter-level dielectric layer(3). A barrier metal membrane(6) is doped on the inter level dielectric layer(3). A copper seed layer is produced on the barrier metal membrane in order to electroplating. A copper layer(7) is built by filling up the via hole(4) and trench(5). A needlessness part of the copper layer(7) is removed by copper electro-polishing. A remaining copper layer(7) in the trench(5) becomes a copper wire(7C) and another remaining part of the copper layer(7) in the via hole(4) becomes a copper plug(7B). The copper wiring is completed by making a capping layer on the copper wire(7C).
