Abstract:
A method for fabricating a ball grid array (BGA) package, comprising the steps of:providing a substrate base, which has first and second surfaces thereof: forming first and second insulating layers on the first and second surfaces of the substrate base, respectively; forming through holes in the substrate base; forming first and second conductive patterns on the first and second insulating layers. respectively, wherein the substrate base, first and second insulating layers and first and second conductive patterns form a substrate; forming a hole in the substrate so that the hole passes through the substrate; mounting a second semiconductor chip on the second surface of the substrate over the hole; injecting a resin into a space between the second semiconductor chip and substrate through the hole; hardening the resin with heat to seal the second semiconductor chip therein; mounting a first semiconductor chip on the first surface of the substrate; providing solder balls on the first surface of the substrate so that the first semiconductor chip is electrically connected through the first conductive pattern to the solder balls and the second semiconductor chip is electrically connected through the second conductive pattern and through holes to the solder balls.
