| Zusammenfassung: | The present invention is directed to a packaged semiconductor chip that utilizes a multilevel leadframe that positions the lead fingers close to the bond pads while positioning the bus bars on a different level and behind or outboard of the lead finger connections such that it is unnecessary for any wires to cross over the bus bars or the lead fingers. The leadframe may comprise a multi-part frame, or be fabricated from a single sheet of metal. |
