1. A method for forming a die-wrapped packaged device, comprising:
placing a die comprising substrate having a back side and a top side semiconductor surface including circuitry thereon having nodes coupled to bond pads with its one of its sides onto a top side of at least one flexible substrate, wherein the flexible substrate further comprises 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
wrapping the flexible substrate over the die, wherein the flexible substrate has a sufficient length relative to the die so that the flexible substrate extends over at least two sidewalls of the die and onto the top side of the die,
wherein the die bonding features are positioned so that after the wrapping they match the positions of the bond pads so that the die bonding features reached the top side of the die and are over the bond pads, and
wherein the flexible substrate comprises a glass-reinforced epoxy laminate material, a paper, or a dielectric metal comprising foil.
