An improvement to an integrated circuit, of electrically conductive
interconnects formed of a superconducting material. In this manner, the
electrically conductive interconnects can be made very small, and yet
still have adequate conductively. In various embodiments, all of the
electrically conductive interconnects are formed of the superconducting
material. In some embodiments, the electrically conductive interconnects
are formed of a variety of different superconducting materials. In one
embodiment, only the backend electrically conductive interconnects are
formed of the superconducting material. In some embodiments no vias are
formed of the superconducting material. The interconductor dielectric
layers are preferably formed of silicon oxide, and sometimes all of the
interconductor dielectric layers are formed of silicon oxide. The
superconducting material is in some embodiments at least one of an
organic compound such as a potassium doped buckminsterfullerene, a cesium
doped buckminsterfullerene, and other carbon containing compounds, a
metallic material such as an inter-metallic material like Nb--Ti alloys
and other substances formed by alloying metals, and an inorganic compound
such as YBa.sub.2Cu.sub.3O.sub.7-x,
(Pb,Bi).sub.2Sr.sub.2Ca.sub.2Cu.sub.3O.sub.10-x and its derivatives,
HgBaCaCuO and its derivatives, and TI--Ba--Ca--Cu--O and its derivatives.
