Classification: CPC H | IPC H

Claim 14:
15. A method, comprising:
attaching a first die to the front side of a substrate, wherein the first die includes a first side facing toward the front side of the substrate and including a first bond pad proximate to a first opening in the substrate and a second bond pad proximate to a second opening in the substrate;
forming a first bonding wire that couples to the first bond pad of the first die and extends through the first opening to couple with a first substrate bond pad on a back side of the substrate;
forming a second bonding wire that couples to the second bond pad of the first die and extends through the second opening to couple with a second substrate bond pad on the back side of the substrate;
attaching one or more second dies to the first die, wherein each of the one or more second dies includes an exposed portion including a third bond pad; and
attaching one or more third bonding wires that couple one or more third bond pads of the one or more second dies with a third substrate bond pad on the first side of the substrate, the third substrate bond pad being directly coupled to the second bond pad by a conductive structure extending through the substrate.
