Integrated circuit inductors with intertwined conductors

Abstract

An inductor may be formed from a conductive path that includes intertwined conductive lines. There may be two, three, or more than three intertwined conductive lines in the conductive path. The conductive lines may be formed from conductive structures in the dielectric stack of an integrated circuit. The dielectric stack may include metal layers that include conductive traces and may include via layers that include vias for interconnecting the traces. The intertwined conductive lines may be formed from the conductive structures in the metal and via layers. In crossover regions, the conductive lines may cross each other without electrically connecting to each other. Vias may be used to couple multiple layers of traces together to reduce line resistance.
