Abstract:
1. A microelectronic assembly comprising: a semiconductor die having microelectronic circuitry thereon, the semiconductor die having a front surface and a rear surface remote therefrom and device contacts exposed at the front surface, and one or more surface conductive elements supported by the semiconductor die and extending along the front surface, wherein the one or more surface conductive elements includes a metal layer at the front surface of the semiconductor die extending along the front surface, each surface conductive element having a planar surface parallel to the front surface; an interconnection element underlying the rear surface of the semiconductor die, the interconnection element having a plurality of element contacts thereon; a plurality of wire bonds connecting the device contacts with the element contacts, the wire bonds disposed above the one or more surface conductive elements, the wire bonds having substantial portions extending at least generally parallel to the one or more surface conductive elements, wherein the one or more surface conductive elements is connectable to a source of reference potential, such that a desired impedance is achieved for the wire bonds.
