Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A manufacturing method of a package structure, comprising:
forming a dielectric layer over a carrier;
providing a die and forming a conductive structure on the dielectric layer and beside the die;
forming an encapsulant surrounding the die and covering the conductive structure;
debonding the carrier and exposing the dielectric layer overlying the conductive structure;
performing a laser drilling process to the dielectric layer to form a first opening in the dielectric layer to expose a top surface of the conductive structure, wherein a top diameter of the first opening is larger than a bottom diameter of the first opening;
performing an etching process to widen the first opening to form a second opening exposing the top surface of the conductive structure, wherein the second opening has a bottom diameter larger than the bottom diameter of the first opening; and
forming a conductive connector in the second opening and on the conductive structure.
