A semiconductor package has a substrate with a plurality of contact pads. A first semiconductor die is mounted to the substrate. First bond wires are formed between each of the center-row contact pads of the first semiconductor die and the substrate contact pads. The first bond wires include an electrically insulative coating formed over the shaft that covers a portion of a surface of a bumped end of the first bond wires. An epoxy material is deposited over the first semiconductor die. A second semiconductor die is mounted to the epoxy material. Second bond wires are formed between each of the center-row contact pads of the second semiconductor die and the substrate contact pads. The second bond wires include an electrically insulative coating formed over the shaft of the second bond wires that covers a portion of a surface of a bumped end of the second bond wires.
