A semiconductor package structure and a method for manufacturing a semiconductor package structure are provided. The semiconductor package structure includes a lower conductive structure, a first semiconductor device and a second semiconductor device. The upper conductive structure is disposed on the lower conductive structure. The second semiconductor device is electrically connected to the first semiconductor device by a first path in the upper conductive structure. The lower conductive structure is electrically connected to the first semiconductor device through a second path in the upper conductive structure under the first path.
