Patent ID: 8508051

Claim:
A semiconductor device comprising: a semiconductor substrate; an interlayer insulating film disposed on the semiconductor substrate; an electrode pad disposed on the interlayer insulating film; a protective film which is disposed on the interlayer insulating film to cover a peripheral portion of the electrode pad, and has a first opening which exposes a center portion of the electrode pad; a divider which is disposed on the electrode pad exposed from the first opening, and divides the first opening into a plurality of second openings; and a barrier metal disposed on the protective film, wherein the divider is interposed between the electrode pad and the barrier metal, and a dividing groove which exposes an upper surface of the divider is disposed in the barrier metal wherein a side surface of the divider is inclined in such a manner that an area of a lower surface of the divider is larger than an area of an upper surface of the divider.
