Abstract

See full text

A method of manufacturing package structures includes providing a carrier including a supporting layer, a metal layer, and a release layer between the supporting layer and the metal layer at first. Afterwards, a composite layer of a non-conductor inorganic material and an organic material is disposed on the metal layer. Then, a chip embedded substrate is bonded on the composite layer. Afterwards, an insulating protective layer having openings is formed on the circuit layer structure and exposes parts of the circuit layer structure in the openings. Afterwards, the supporting layer and the release layer are removed to form two package substrates. Then, each of the package substrates is cut.
