Patent ID: 7374969

Claim:
A method of manufacturing a semiconductor package, comprising the steps of: (A) providing a substrate having an insulating substrate, substrate pads on the insulating substrate, and ball pads electrically connected to the substrate pads; (B) forming through holes by piercing the substrate and filling the through holes with conductive lines formed of a first conductive material; (C) mounting a semiconductor chip on the substrate, and electrically connecting chip pads on the semiconductor chip to the substrate pads via connecting means; (D) applying an insulation coating layer onto the chip pads, the substrate pads, and the connecting means by spraying an insulation coating solution thereon; (E) sealing the semiconductor chip, the connecting means, and the conductive lines with a conductive molding compound containing a second conductive material to electrically connect a first end of each conductive line to the conductive molding compound; and (F) forming solder balls on the ball pads and a second end of each conductive line for external electrical connections.
