Abstract:
1. A microelectronic assembly comprising: an interconnection element including a dielectric element, a plurality of element contacts and at least one reference contact thereon; a microelectronic device comprising a semiconductor chip, the semiconductor chip having a rear surface overlying the dielectric element, a front surface remote therefrom, device contacts exposed at the front surface, and at least one surface conductive element attached to the front surface, the surface conductive element including at least one opening in which at least one of the device contacts is exposed; a plurality of raised conductive elements connecting the device contacts with the element contacts, the raised conductive elements having substantial portions spaced a first height above and extending at least generally parallel to the at least one surface conductive element, such that a desired impedance is achieved for the raised conductive elements; and a bond wire electrically connecting the at least one surface conductive element with the at least one reference contact, wherein the at least one reference contact is connectable to a source of reference potential.
