Semiconductor package device
This invention relates to a wafer-leveled chip packaging method, comprising the steps of: providing a wafer; attaching at least one first chip to the wafer; forming a first insulating layer on the wafer; forming a plurality of first conductive vias penetrating the first insulating layer, wherein parts of the first conductive vias are electrically connected with the first chip; forming a conductive pattern layer on the surface of the first insulating layer wherein the conductive pattern layer is electrically connected with the first conductive vias; forming a plurality of through holes penetrating the wafer; filling a second insulating layer in the through holes; and forming a plurality of second conductive vias in the second insulating layer, wherein the second conductive vias are electrically connected with the first conductive vias.
