Patent ID: 7990727

Claim:
A multi-layer electronic package comprising: a first layer including opposing major surfaces, a first layer lateral surface, an opposite lateral surface on an opposite side of the first layer as the first layer lateral surface, and a first layer conductive trace, wherein each of the opposing major surfaces includes an electronic component disposed thereon, wherein at least one of the opposing major surfaces extends from the first layer lateral surface to the opposite lateral surface, and wherein the first layer conductive trace terminates on the first layer lateral surface to define a first layer access lead; a separately-formed interposer structure formed of a dielectric material and defining an interposer lateral surface, wherein the interposer structure has an aperture; a second layer including a second layer lateral surface and a second layer conductive trace, wherein the second layer conductive trace terminates on the second layer lateral surface to define a second layer access lead, wherein the first layer, the interposer structure, and the second layer are bonded together, wherein the first layer lateral surface, the interposer lateral surface, and the second layer lateral surface define a substantially coplanar package lateral surface, and wherein the interposer structure is disposed between the first and second layers; a conductive layer interconnect trace defined on the substantially coplanar package lateral surface, wherein the first layer access lead and the second layer access lead are in electrical communication; and a conductive member disposed on an outside surface of the multi-layer electronic package, wherein the conductive member is electrically connected to the second layer conductive trace and is configured for electrical connection with an external conductive pattern; wherein the aperture is configured to receive the electronic component from the first or second layer, and wherein there is an unfilled gap in the aperture between the interposer and the electronic component.
