Classification: CPC H | IPC H

Claim 11:
12. A method of forming package structure, comprising:
providing a die;
forming an encapsulant, encapsulating sidewalls of the die; and
forming a redistribution layer (RDL) structure on the die and the encapsulant, wherein the RDL structure comprises:
forming a first dielectric structure comprising a first dielectric material layer and a second dielectric material layer on the first dielectric material layer; and
forming a first redistribution layer, embedded in the first dielectric structure and electrically connected to the die, the first redistribution layer comprises a first seed layer and a first conductive layer disposed on the first seed layer,
wherein a topmost surface of the first seed layer and a topmost surface of the first conductive layer are substantially level with a top surface of the second dielectric material layer.
