Patent ID: 7230338

Claim:
A semiconductor device, comprising: a semiconductor section; an element formed on the semiconductor section; an insulating layer disposed above the semiconductor section and defining a contact hole; an electrode pad disposed on the insulating layer, the electrode pad including a first section, a second section, an upper surface and a lower surface; a contact section including a conductive material provided in the contact hole, the contact section being electrically connected with the lower surface of the electrode pad; a passivation film defining an opening on the first section of the electrode pad, the passivation film being disposed on the second section of the electrode pad; a bump being larger than the opening in the passivation film, the bump being partially disposed on the passivation film and being electrically connected with the upper surface of the electrode pad in the first section; and a barrier layer which lies between the electrode pad and the bump, wherein the contact section is connected with the second section at a position within a range in which the contact section overlaps the bump while avoiding the first section of the electrode pad, and wherein the upper surface of the electrode pad defines a depression at a position at which the electrode pad overlaps the contact section.
