Claim:
1. A package structure, comprising: a die; an encapsulant aside the die; a through via aside the die penetrating through the encapsulant; a first dielectric layer overlying the die, the encapsulant and overlapping the through via; a conductive line structure comprising a pad over the first dielectric layer; an adhesion promotion layer overlying a first portion of a top surface of the pad and along a periphery of the pad, overlying a sidewall of the pad and overlying the first dielectric layer; a second dielectric layer overlying the adhesion promotion layer, wherein the adhesion promotion layer has an opening and a portion of the second dielectric layer disposed within the opening of the adhesion promotion layer is in contact with the underlying first dielectric layer; and a connector being in contact with a second portion of the top surface of the pad, wherein the second portion of the top surface of the pad is exposed by the adhesion promotion layer.
