Classification: CPC H | IPC H

Claim 9:
10. A semiconductor package structure, comprising:
a first package, comprising:
a first substrate having a first surface and a second surface opposite to the first surface;
a trace layer embedded in the first substrate and proximal to the first surface of the first substrate;
a first conductive pillar connected to the trace layer; and
a first conductive via connecting the first conductive pillar to the second surface of the first substrate, wherein the first conductive via and the first conductive pillar are within a same layer of the first substrate;

a second package disposed on the first surface of the first substrate of the first package; and
a conductive layer below the first conductive via, and a thickness of the conductive layer is less than a thickness of the trace layer.
