Abstract:
A method of forming a metal wire in a semiconductor device is disclosed The method includes the steps of etching an insulating layer formed on a semiconductor substrate to form a dual damascene pattern, forming a barrier metal layer in the dual damascene pattern, forming a metal layer on the barrier metal layer, and filling the dual damascene pattern with a conductive material to form a metal wire.
