Abstract:
1. A microelectronic assembly comprising: a microelectronic device having a surface and device contacts exposed at the surface, the surface having a first dimension in a first direction and a second dimension in a second direction transverse to the first direction; an interconnection element having a face adjacent to the microelectronic device and having a plurality of element contacts; a plurality of conductive elements connecting the device contacts with the element contacts, the conductive elements having substantial portions extending in runs above the surface of the microelectronic device; and a conductive material having a conductive surface disposed at least a substantially uniform distance at least above or below the plurality of the runs, the conductive material having a first dimension in the first direction and a second dimension in the second direction, wherein each of the first and second dimensions of the conductive material is smaller than the first and second dimensions of the microelectronic device, wherein the conductive material is connectable to a source of reference potential, such that a desired impedance is achieved for the conductive elements.
