Abstract
A semiconductor package structure includes a redistribution structure and an impedance matching device. The redistribution structure includes a first surface, a second surface opposite to the first surface and a circuitless region extending from the first surface to the second surface. The impedance matching device is disposed on the redistribution structure and includes at least one impedance matching circuit aligned with the circuitless region.
