A method of fabricating a packaging substrate is provided, which includes: forming on a carrier a conductor layer having a plurality of openings; forming a plurality of conductive bumps on the conductor layer, wherein each of the conductive bumps has a post body disposed in a corresponding one of the openings and a conductive pad disposed on the conductor layer, the post body being integrally formed with the conductive pad and less in width than the conductive pad; forming a plurality of conductive posts on the conductive pads; forming on the carrier a first insulating layer that encapsulates the conductive bumps and the conductive posts; removing the carrier; and removing the entire conductor layer to expose the post bodies from a first surface of the first insulating layer. As such, a semiconductor chip can be bonded to the packaging substrate through the conductive bumps.
