Abstract: A semiconductor device has a die support and external leads formed integrally from a single sheet of electrically conductive material. A die mounting substrate is mounted on the die support, with bonding pads coupled to respective external connection pads on an external connector side of the substrate. A die is attached to the die mounting substrate with die connection pads. Bond wires selectively electrically couple the die connection pads to the external leads and the bonding pads and electrically conductive external protrusions are mounted to the external connection pads. An encapsulant covers the die and bond wires. The external protrusions are located at a central region of a surface mounting side of the package and the external leads project outwardly from locations near the die support towards peripheral edges of the package.
