Patent ID: 8387240

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 metal pads on the upper surface and second metal pads in contact with the first metal pads, the second metal pads having a denser pitch between adjacent pads than the first metal pads; forming a dielectric layer between the adjacent first metal pads and forming a dielectric layer between the adjacent second metal pads, wherein at least one of the vias is covered by a portion of the dielectric layer between adjacent first metal pads thinning the body through a lower surface and exposing the electrically insulating layer in the vias; after the thinning the body, coupling a plurality of electronic elements to the second metal pads; removing a portion of the electrically insulating layer in the vias; and coupling body to a substrate, wherein the body is positioned between the electronic elements and the substrate.
