A semiconductor package structure and a method for manufacturing a semiconductor package structure are provided. The semiconductor package structure includes a first package and a second package. The first package includes a first substrate, an electronic component, a trace layer, and a first conductive structure. The first substrate has a first surface and a second surface opposite to the first surface. The electronic component is embedded in the first substrate. The trace layer has an uppermost conductive layer embedded in the first substrate and exposed from the first surface of the first substrate. The first conductive structure electrically connects the trace layer to the second surface of the first substrate. The second package is disposed on the first surface of the first substrate of the first package.
