Abstract
A semiconductor structure includes a semiconductor chip, a substrate and a plurality of bump segments. The bump segments include a first group of bump segments and a second group of bump segments collectively extended from an active surface of the semiconductor chip toward the substrate. Each bump segment of the second group of bump segments has a cross-sectional area greater than a cross-sectional area of each bump segment of the first group of bump segments. The first group of bump segments includes a first bump segment and a second bump segment. Each of the first bump segment and the second bump segment includes a tapered side surface exposed to an environment outside the bump segments. A portion of a bottom surface of the second bump segment is stacked on the first bump segment, and another portion of the bottom surface of the second bump segment is exposed to the environment.
