A semiconductor package is provided. In one configuration, the semiconductor package includes a substrate. First and second conductive traces are disposed on the substrate. A conductive pillar bump is disposed on the second conductive trace, and a first conductive structure is disposed between the second conductive trace and the conductive pillar bump or between the second conductive trace and the substrate. A semiconductor die is disposed over the first conductive trace, wherein the conductive pillar bump connects to the semiconductor die.
