Patent ID: 8552552

Claim:
A semiconductor device comprising: (a) a semiconductor substrate; (b) a semiconductor element formed over the semiconductor substrate; (c) a first wiring formed over the semiconductor element; (d) a first insulating film formed over the semiconductor substrate to cover the semiconductor element and the first wiring; (e) a pad formed over the first insulating film; (f) a second insulating film having a portion formed over the pad and an opening which reaches the pad; and (g) a bump electrode formed over the second insulating film and electrically coupled to the pad by way of the opening, wherein in a same layer as the pad, a second wiring and a dummy pattern different from the second wiring are formed, wherein respective portions of the second wiring and the dummy pattern are disposed under the bump electrode, and wherein a long side of the dummy pattern extends in a direction transverse to a long-side direction of the second wiring in a plan view.
