Abstract
In a semiconductor device having a semiconductor substrate, an internal electrode layer is formed on the semiconductor substrate. A barrier metal layer is formed on the internal electrode. An external electrode layer is formed on the barrier metal layer. A pad electrode is made of the internal electrode layer, the barrier metal layer, and the external electrode layer. A wire is electrically connected to the pad electrode. An area of the external electrode layer is set midway between an area of a polymerization portion of the wire on the pad electrode and a planar area of the barrier metal layer.
