Patent ID: 7841080

Claim:
A method comprising: forming a plurality of vias extending partially through a body, the vias including sidewalls defined by the body; forming an electrically insulating layer on the sidewalls in the vias and on an upper surface of the body; forming an electrically conductive layer on the electrically insulating layer in the vias and on the upper surface, the electrically conductive layer defining first medal pads on the upper surface and second medal pads in contact with first medal pads, second medal pads having a denser pitch than the first metal pads; forming a dielectric layer between adjacent first metal pads and forming a dielectric layer between adjacent second metal pads; coupling a plurality of electronic elements to the second metal pads; after the coupling the electronic elements, thinning the body through a lower surface and exposing the electrically insulating layer in the vias; removing a portion of the electrically insulating layer in the vias; and coupling the body to a substrate, wherein the body is positioned between the elements and the substrate.
