Abstract

A microelectronic assembly is disclosed that is capable of achieving a desired impedance for raised conductive elements. The microelectronic assembly may include an interconnection element, a surface conductive element, a microelectronic device, a plurality of raised conductive elements, and a bond element. The microelectronic device may overlie the dielectric element and at least one surface conductive element attached to the front surface. The plurality of raised conductive elements may connect the device contacts with the element contacts. The raised conductive elements may have substantial portions spaced a first height above and extending at least generally parallel to at least one surface conductive element, such that a desired impedance may be achieved for the raised conductive elements. A bond element may electrically connect at least one surface conductive element with at least one reference contact that may be connectable to a source of reference potential.
