Abstract:
Disclosed is a semiconductor device suppressed in decrease of reliability. The semiconductor device comprises an electrode pad portion ( 2 ) formed on the upper surface of a semiconductor substrate ( 1 ), a passivation layer ( 3 ) so formed on the upper surface of the semiconductor substrate ( 1 ) as to overlap a part of the electrode pad portion ( 2 ) and having a first opening portion ( 3 a ) where the upper surface of the electrode pad portion ( 2 ) is exposed, a barrier metal layer ( 5 ) formed on the electrode pad portion ( 2 ), and a solder bump ( 6 ) formed on the barrier metal layer ( 5 ). The barrier metal layer ( 5 ) is formed such that an outer peripheral end ( 5 b ) lies within the first opening portion ( 3 a ) of the passivation layer ( 3 ) when viewed in plan.

Claim (Index 11):
A semiconductor device comprising:\n an electrode pad portion on a face of a substrate; a first protection layer including a first opening through which a top face of the electrode pad portion is exposed, the first protection layer disposed on the face of the substrate and overlapping part of the electrode pad portion; a barrier metal layer on the electrode pad portion; a second protection layer covering a region on the first protection layer and a region on the electrode par portion; and a bump electrode on the barrier metal layer, wherein the barrier metal layer has a circumferential end part thereof formed inward of the first opening in the first protection layer as seen in a plan view, wherein the electrode pad portion is rectangular as seen in a plan view; wherein\n a peripheral part of the barrier metal layer lies on the second protection layer, and \n an upper surface and a lower surface of the barrier metal layer have a curved shape extending along the second protection layer so that a center point of a curvature of the curved shape as seen in a sectional view is located on a substrate side of the curved shape, and \n wherein\n the second protection layer is formed of polyimide, \n the second protection layer has a second opening through which the top face of the electrode pad portion is exposed and which has an opening width smaller than the first opening, and \n a thickness of the second protection layer as seen in a sectional view increases gradually from a rim part of the second opening to the peripheral part of the barrier metal layer.
