Patent ID: 8865521

Claim:
A method of forming a semiconductor device, the method comprising: attaching one or more first dies to a first side of an interposer using conductive bumps, wherein the conductive bumps are attached to bond pads on a first side of the interposer; attaching one or more second dies to a second side of the interposer using conductive bumps, wherein the conductive bumps are attached to bond pads on a second side of the interposer; attaching the interposer to a first side of a substrate after the attaching the one or more first dies and the one or more second dies to the interposer, such that at least one of the one or more second dies is positioned within a cavity in the substrate; and forming a plurality of connectors on the second side of the substrate opposite the first side of the substrate, at least a portion of the plurality of connectors aligned under the cavity.
