Claim 0:
1. A package structure, comprising:
a polymer layer;
a redistribution layer over the polymer layer;
a die sandwich between the polymer layer and the redistribution layer; and
an adhesion promoter layer, an oxide layer, a through via, and an encapsulant sandwich between the polymer layer and the redistribution layer, wherein
the encapsulant laterally encapsulates the die;
the through via extends through the encapsulant;
the adhesion promoter layer and the oxide layer are laterally sandwiched between the through via and the encapsulant,
wherein a bottom portion of the encapsulant is longitudinally sandwiched between the adhesion promoter layer and the polymer layer.
