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 22):
A method of fabricating a package structure, comprising:\n providing a semiconductor die having a warpage control layer formed thereon, wherein the semiconductor die comprises a semiconductor substrate located at a backside of the semiconductor die, and a plurality of conductive posts located at an active surface opposite to the backside of the semiconductor die, and the warpage control layer is attached to the backside of the semiconductor die on the semiconductor substrate, and formed with a material having a Young's Modulus of 100 GPa or more; bonding the semiconductor die onto a carrier through the warpage control layer; and forming a plurality of through insulator vias on the carrier, wherein the plurality of through insulator vias is surrounding the semiconductor die; forming an insulating encapsulant on the carrier after forming the plurality of through insulator vias to encapsulate the semiconductor die, the warpage control layer and the plurality of through insulator vias.
