Abstract:
A die-wrapped packaged device includes at least one flexible substrate having a top side and a bottom side that has lead terminals, where 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. At least one die includes a substrate having a back side and a topside semiconductor surface including circuitry thereon having nodes coupled to bond pads. One of the sides of the die is mounted on the top side of the flexible circuit, and 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 flexible substrate so that the die bonding features contact the bond pads.
