Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A method of forming a package structure, comprising:
providing a die;
forming an encapsulant to laterally encapsulate the die;
forming a dielectric layer on the die and the encapsulant;
forming a recess in the dielectric layer to expose a connector of the die;
forming a seed layer in the recess and on a top surface of the dielectric layer;
forming a conductive layer on the seed layer, wherein an orthographic projection area of the conductive layer on the top surface of the dielectric layer is less than an orthographic projection area of the seed layer on the top surface of the dielectric layer; and
removing excess portions of the conductive layer and the seed layer over the top surface of the dielectric layer to expose a portion of the top surface of the dielectric layer.
