Classification: CPC H  B | IPC B  H

Claim 20:
21. A method, comprising:
providing at least one flexible substrate having a top side and a bottom side that has lead terminals, wherein the top side has outer positioned die bonding features coupled by traces to through-vias that couple through a thickness of the flexible substrate to the lead terminals, and
at least one die comprising a substrate having a back side and a top side semiconductor surface including circuitry thereon having nodes coupled to bond pads,
wherein one of the sides of the die is mounted on the top side of the flexible circuit,
wherein the flexible substrate has a sufficient length relative to the die so that the flexible substrate wraps to extend over at least two sidewalls of the die onto the top side of the die and so that the die bonding features contact the bond pads, and
wherein the flexible substrate comprises a glass-reinforced epoxy laminate material, a paper, or a dielectric metal comprising foil.
