Patent ID: 8237060

Claim:
A method for manufacturing a multilayer printed wiring board having an electronic component housed therein, the method comprising: forming a first conductor circuit on a first surface of a substrate; forming a first alignment mark on the first surface of the substrate separate from the conductor circuit, wherein the forming a first conductor circuit and the forming a first alignment mark are performed simultaneously in a same process step; forming a through opening in the substrate, the through opening extending from the first surface of the substrate to a second surface of the substrate; disposing a seal member on the second surface of the substrate, the seal member sealing an opening on the second surface of the through opening to provide a sealed through opening; inserting an electronic component in the sealed through opening using the first alignment mark on the first surface of the substrate; forming a first interlayer insulating layer on the first surface of the substrate and on the electronic component; and forming a first via hole opening in the first interlayer insulating layer by using the first alignment mark to align the first via hole opening with a terminal of the electronic component such that electrical connection can be made to the electronic component by way of the first via hole opening.
