Abstract
A semiconductor package includes an encapsulated semiconductor device, a backside redistribution structure, and a front side redistribution structure. The encapsulated semiconductor device includes an encapsulating material and a semiconductor device encapsulated by the encapsulating material. The backside redistribution structure is disposed on a backside of the encapsulated semiconductor device and includes a redistribution circuit layer and a first patterned dielectric layer. The redistribution circuit layer has a circuit pattern and a dummy pattern electrically insulated from the circuit pattern. The dummy pattern is overlapped with the semiconductor device from a top view of the semiconductor package. The first patterned dielectric layer is disposed on the redistribution circuit layer and includes a marking pattern disposed on the dummy pattern and revealing a part of the dummy pattern. The front side redistribution structure is disposed on a front side of the encapsulated semiconductor device and electrically connected to the semiconductor device.
