Abstract:
1. A semiconductor structure, having a first direction and a second direction, the second direction being perpendicular to the first direction, and the semiconductor structure comprising: a substrate; at least two pads, being disposed on the substrate adjacent to each other along the first direction; a passivation layer, being disposed on and covering the substrate and a peripheral upper surface of each of the pads and defining an opening corresponding to each of the pads; at least two UBM layers, being respectively disposed on the opening of each of the pads; and at least two bumps, being respectively disposed on the at least two UBM layers, wherein, each of the openings defines an opening projection along the second direction at a projection plane, and the two opening projections defined by any two of the adjacent openings are not overlapped with each other.
