Abstract:
A package structure including a semiconductor die, a warpage control layer, an insulating encapsulant and a redistribution layer is provided. The semiconductor die has an active surface and a backside surface opposite to the active surface. The warpage control layer is disposed on the backside surface of the semiconductor die, wherein the warpage control layer comprises a material having a Young's Modulus of 100 GPa or more. The insulating encapsulant is encapsulating the semiconductor die and the warpage control layer. The redistribution layer is located on the insulating encapsulant and over the active surface of the semiconductor die.

Claim (Index 14):
A method of fabricating a package structure, comprising:\n providing a semiconductor die, the semiconductor die has an active surface and a backside surface opposite to the active surface; forming a warpage control layer on the backside surface of the semiconductor die by plasma-enhanced chemical vapor deposition, wherein the plasma enhanced chemical vapor deposition is performed at temperatures below 200\u00b0 C.; bonding the semiconductor die and the warpage control layer onto a carrier; forming a plurality of through insulator vias on the carrier to surround the semiconductor die and the warpage control layer; forming an insulating encapsulant on the carrier to encapsulate the semiconductor die, the warpage control layer and the plurality of through insulator vias, wherein the insulating encapsulant has a first surface and a second surface opposite to the first surface; forming a redistribution layer on the first surface of the insulating encapsulant, wherein the redistribution layer is electrically connected to the semiconductor die; de-bonding the carrier; and forming a plurality of conductive balls on the second surface of the insulating encapsulant.
