Claim 14:
15. A method of manufacturing a package structure, comprising:
forming a plurality of through vias around a die;
forming an encapsulant to laterally encapsulate the die and the plurality of through vias;
forming a plurality of connectors to electrically connect to the plurality of through vias;
forming a warpage control material over a first surface of the die; and
forming a protection material over a first surface of the encapsulant, around the plurality of connectors and the warpage control material,
wherein a Young's modulus of the warpage control material is greater than a Young's modulus of the encapsulant, and the Young's modulus of the encapsulant is greater than a Young's modulus of the protection material.
