Abstract:
1. An integrated circuit (IC) device, comprising: at least one electrical interconnect, the electrical interconnect having a first end and a second end; and a dielectric material applied to at least a portion of the at least one electrical interconnect, the dielectric material having a controllable characteristic associated therewith, wherein the controllable characteristic of the dielectric material is selectively adjustable so that an impedance of the electrical interconnect is substantially matched to at least one impedance at the first and second ends of the interconnect; wherein the dielectric material comprises a polymeric carrier impregnated with dielectric particles, such that a dielectric constant of the dielectric material is controllable by varying at least one of: (i) a material of the dielectric particles; and (ii) a loading percentage of the dielectric particles, the impedance of the at least one electrical interconnect being a function of the dielectric constant of the dielectric material.
