Claim 17:
18. The method of claim 17, wherein forming the adhesion promoter layer, the oxide layer, the through via, and the encapsulant comprise:
performing a treatment process on the through via to form an adhesion promoter material layer on the sidewalls and a top surface of the through via;
forming an encapsulant material layer to encapsulant sidewalls and a top surface of the die, and sidewalls and a top surface of the adhesion promoter material layer; and
performing a planarization process to remove a portion of the encapsulant material layer over the top surface of the die and the top surface of the through via, and a portion of the adhesion promoter layer on the top surface of through via.
