==Original Abstract Submitted==

An integrated circuit (IC) package comprises a semiconductor die having a first surface with a Hall-effect sensor circuit and a second surface. A plurality of through substrate vias (TSV) each having a metal layer extend from the first surface of the semiconductor die to the second surface. The IC package includes a portion of a leadframe having a first set of leads and a second set of leads. The first set of leads provide a field generating current path for directing a magnetic field toward the Hall-effect sensor circuit. The second set of leads are attached to bond pads on the semiconductor die. A first side of an insulator is attached to the leadframe using a die attach material, and a second side of the insulator is attached to the first side of the semiconductor die using a bonding material.
