Abstract
A manufacturing method of a package structure includes at least the following steps. At least one first die is disposed over a carrier. The first die is encapsulated using a first encapsulant. The first encapsulant exposes part of the first die. A redistribution layer (RDL) is formed over the first encapsulant. The RDL has a first surface and a second surface opposite to the first surface. The first surface faces the first encapsulant. The first encapsulant and the first die are separated from the carrier. A plurality of second dies are disposed on the second surface of the RDL. The second dies are encapsulated using the second encapsulant. A plurality of conductive terminals are formed on the first surface of the RDL.
