ABSTRACT:
A leading wiring layer is provided with a main conductor layer, a first barrier metal layer for covering bottom and side surfaces of the main conductor layer, and a second barrier metal layer for covering a top surface of the main conductor layer. This ensures the respective barrier metal layers to cover entire surroundings including the side, bottom and top surfaces of the main conductor layer.
