Classification: CPC H  Y | IPC H

Claim 8:
9. An electronic device, comprising:
an under layer (UL) of a mold material and comprising a top UL side, a bottom UL side, and a UL aperture that extends between the top UL side and the bottom UL side;
an interposer dielectric layer comprising a top side and a bottom side, wherein the bottom side of the interposer dielectric layer outwardly faces the top UL side and is coupled to the under layer (UL) via the top UL side;
an interposer conductive layer comprising a top side and a bottom side, wherein the bottom side of the interposer conductive layer is coplanar with the bottom side of the interposer dielectric layer, and wherein at least a portion of the bottom side of the interposer conductive layer is exposed through the under layer (UL) by the UL aperture;
an upper dielectric layer on the top side of the interposer dielectric layer;
an upper conductive layer on the top side of the interposer conductive layer; and
a lower signal distribution structure comprising a lower signal distribution structure top side, wherein the lower signal distribution structure top side outwardly faces the bottom UL side and is electrically coupled to the interposer conductive layer via the UL aperture and the bottom side of the interposer conductive layer; and
wherein the mold material of the under layer (UL) is a remnant of a thinned layer.
