Abstract

A packaging method includes providing a substrate structure, including a core substrate, a plurality of first conductive pads at a first surface of the core substrate, and a plurality of packaging pads at a second surface of the core substrate; and packaging a plurality of semiconductor chips onto the substrate structure at the second surface of the core substrate, including forming a first metal wire to connect with a chip-contact pad of a semiconductor chip, and forming a molding compound on the second surface of the core substrate to encapsulate the plurality of semiconductor chips. One end of the first metal wire connects to the chip-contact pad, and another end of the first metal wire is exposed at the surface of the molding compound. The packaging method further includes forming a first metal pad on the surface of the molding compound to electrically connect with the first metal wire.
