  • Publication number: 20240055387
    Abstract: A semiconductor package includes: a semiconductor die attached to a lead frame and having a first bond pad at a side of the semiconductor die facing away from the lead frame; a metal clip having a first bonding region attached to the first bond pad by a solder joint, the metal clip providing an electrical pathway to the first bond pad; and an additional electrical pathway to the first bond pad. A first end of the additional electrical pathway is attached to the first bond pad. At one or more locations between the first end and a second end of the additional electrical pathway, the additional electrical pathway is attached to a surface of the first bonding region of the metal clip that faces away from the first bond pad. Methods of producing the semiconductor package are also described.
