Abstract

A semiconductor device package includes a lower redistribution structure, an upper encapsulated semiconductor device and an upper redistribution structure. The lower redistribution structure includes a first dielectric layer, a RDL, a second dielectric layer, and a second RDL. The first RDL is disposed on the first dielectric layer and includes a circuit portion and an alignment mark portion insulated from the circuit portion. The second dielectric layer is disposed on the first RDL, wherein the second dielectric layer covers the alignment mark portion. The second RDL is disposed on the second dielectric layer and electrically connected to the first RDL. The upper encapsulated semiconductor device is disposed on the lower redistribution structure. The upper redistribution structure is disposed on the upper encapsulated semiconductor device.
