Abstract:
A method for fabricating a semiconductor structure includes forming a semiconductor chip. Forming the semiconductor chip includes providing a substrate, forming a connection layer on the substrate, and forming a first passivation layer on the substrate. The first passivation layer contains a plurality of first openings to expose the connection layer. Forming the semiconductor chip also includes forming a plurality of second openings and a plurality of third openings in the second passivation layer. Each second opening is formed in a first opening to expose the connection layer, and each third opening is formed outside of the plurality of first openings to expose the first passivation layer. Further, forming the semiconductor chip includes forming a conductive bump in each second opening.

Claim (Index 9):
The method according to  claim 1 , forming the conductive bump in each second opening includes:\n forming a metal film on sidewall and bottom surfaces of the plurality of second openings, wherein the metal film also covers the second passivation layer as well as sidewall and bottom surfaces of the plurality of third openings; forming a second patterned layer on the metal layer, wherein a fourth opening is formed in the second patterned layer to expose the metal layer in the second opening; forming a metal pillar in the fourth opening by filling a metal material into the fourth opening; forming a metal cap on top of the metal pillar; removing the second patterned layer and a portion of the metal film formed under the second patterned layer to expose the second passivation layer and the plurality of third openings, wherein:\n a portion of the metal film formed in the fourth opening becomes a under bump metal (UBM) layer; and \n the metal cap, the metal pillar, and the UBM layer together form the conductive bump.
