Abstract:
1. The microelectronic assembly comprising: a microelectronic device having device contacts exposed at a surface thereof; an interconnection element having a plurality of signal contacts and a plurality of reference contacts, the reference contacts being connectable to a source of reference potential; signal bond wires electrically coupling the device contacts with the signal contacts, the signal bond wires having substantial portions extending above the surface of the microelectronic device and extending in a direction parallel to the surface of the microelectronic device; reference bond wires each coupled with the reference contacts and having portions spaced at an at least substantially uniform spacing from the signal band wires, each such portion having a length of at least 50% of a length of a respective signal wire bond from which the portion has the substantially uniform spacing, at least one of the reference bond wires being coupled with two reference contacts of the interconnection element, such that a desired impedance is achieved for the signal bond wires.
