Abstract
A chip packaging method begins by fixing a chip to the top side of a substrate. The chip is then encapsulated in an encapsulant. After that, the encapsulant is drilled from its top side in order to have a through hole adjacent to the chip. Lastly, an area extending between the chip and the through hole and the hole wall of the through hole are plated with an electrically conductive metal to enable electrical connection between the chip and the substrate through the electrically conductive metal. The chip packaging method solves the problems of the conventional wire bonding method, simplifies the packaging process, and provides the packaged chips with high transmission efficiency.
