Abstract

A semiconductor package includes a conductive pillar and a solder. The conductive pillar has a first sidewall and a second sidewall opposite to the first sidewall, wherein a height of the first sidewall is greater than a height of the second sidewall. The solder is disposed on and in direct contact with the conductive pillar, wherein the solder is hanging over the first sidewall and the second sidewall of conductive pillar.
