Patent ID: 8134841

Claim:
A printed-wiring board, comprising: a first base member comprising a component mounting face; a first electronic component with a through-electrode mounted on the component mounting face; a second base member stacked on an insulating layer covering the first electronic component; a tapered, continuous via hole conductor provided in the second base member and in the insulating layer and communicating to communicate electrically with the through-electrode of the first electronic component; and a second electronic component mounted on the second base member and comprising an electrode electrically connected to the through-electrode by way of the tapered, continuous via hole conductor; wherein the first electronic component is a semiconductor chip component provided with a plurality of through-electrodes, and the location of the hole corresponds to a predetermined one of the plurality of through-electrodes; wherein the through-electrodes are divided into a first group of through-electrodes and a second group of through-electrodes, and wherein the first base member comprises a plurality of pads joined to the first group of the through-electrodes, and wherein the second base member comprises a plurality of vias joined to the second group of the through-electrodes.
