Abstract
The reliability of a copper wire is improved without inhibiting the wiring resistance of the copper wire. For example, another metallic element segregates in the boundary region between a copper film CUFand a copper film CUF, and at the upper side face part of a wiring gutter leading to the boundary region. In a sectional view, a metallic element having a reducing power higher than copper segregates at the inner part of the copper wire apart from both the surface of the copper wire and the bottom face of the wiring gutter and at the side face part of the copper wire. In a sectional view, a metallic element different from copper segregates in the vicinity of the center part of the copper wire and at the side face part of the copper wire.
