Classification: CPC H | IPC H

Claim 16:
17. A method of fin wing a package structure, comprising:
forming a through via on a first conductive feature structure;
forming an insulator on the first conductive feature structure;
mounting a die on the insulator over the first conductive feature structure through an adhesive layer, wherein the adhesive layer is disposed between the die and the insulator; and
forming an encapsulant on the insulator and the first conductive feature structure to laterally encapsulate sidewalls of the die, wherein the insulator has a bottom surface in physical contact with a polymer layer of the first conductive feature structure,
wherein the through via extends through the encapsulant to connect to the first conductive feature structure,
wherein the insulator comprises a coefficient of thermal expansion lager than a coefficient of thermal expansion of the die and less than a coefficient of thermal expansion of the encapsulant.
