Surface mounted type semiconductor device with wrap-around external leads

摘要

A semiconductor device of surface-mount type includes a circuit strip tailored to have patterns projected, a semiconductor element fixedly joined to the circuit strip, and pads on the semiconductor element electrically connected by wires to the corresponding patterns on the circuit strip and sealed with a resin material. While the surface-mount type semiconductor device is adapted to be simple in structure and capable of high-density mounting, an appliance on which the semiconductor device is mounted and a method of producing the semiconductor device are also provided.
