Abstract:
A bump structure includes an under bump metal (UBM) layer, a pillar bump and a capping layer. The UBM layer is disposed on a pad of a semiconductor chip. The pillar bump is disposed on the UBM layer. The capping layer is disposed on the UBM layer and surrounds an outer surface of the pillar bump. The capping layer has a height of about 0.5 times to 0.7 times a height of the pillar bump as measured from the UBM layer where an upper portion of the pillar bump is exposed. The capping layer suppresses stresses applied to a metal wiring in the semiconductor chip while attaching the semiconductor chip to a package substrate and maintain an adhesion force between the pillar bump and the package substrate.

Claim (Index 5):
A semiconductor package comprising:\n a package substrate; a first semiconductor chip disposed over the package substrate; and a first bump structure that includes a first under bump metal (UBM) layer disposed on a pad of the first semiconductor chip, a first pillar bump disposed on the first UBM layer and that is electrically connected with the package substrate, and a first capping layer disposed on an edge of the first UBM layer that surrounds the first pillar bump, the first capping layer having a height of about 0.5 times to about 0.7 times a height of the first pillar bump as measured from the first UBM layer wherein an upper portion of an outer side surface of the first pillar bump oriented toward the package substrate is exposed.
