Patent ID: 7151312

Claim:
A semiconductor device, comprising: a semiconductor substrate having disposed thereon circuitry; an electrode pad disposed over the substrate and electrically interfaced with the circuitry; an insulating layer disposed over said substrate and having a pad opening for exposing at least a portion of a surface of the electrode pad; an intermediate layer disposed over an upper surface of said electrode pad and extending beyond a periphery of the pad opening such that a portion of the intermediate layer overlies said insulating layer with a peripheral edge of the intermediate layer disposed above the surface of the insulating layer and outside of the pad opening; a bump formed above the intermediate layer with an interface being defined by the bump and the intermediate layer, the bump being electrically interfaced to the electrode pad through the intermediate layer; and a resin insulating film that directly covers the peripheral edge of the intermediate layer and the interface defined by the bump and the intermediate layer to prevent exposure of the interface.
