ABSTRACT:
A high density electrical interconnect having a plurality of metallic conductors supported from metallic pillars which are electrically isolated from the ground plane by openings. The interconnect can be fabricated using a temporary support dielectric, which may be removed after completion to provide an air dielectric or be replaced with a more suitable permanent dielectric. The removal of the temporary support allows the conductors to be coated with protective layers or with a layer of a higher conductivity.
