An inductor for an integrated circuit or integrated circuit package
comprises a three-dimensional structure. In one embodiment the inductor
is arranged on an integrated circuit substrate in at least two rows, each
row comprising upper segments and lower segments, with the upper segments
being longer than the lower segments. The upper segments in a first row
are offset 180 degrees from those in an adjoining row to provide greater
coupling of magnetic flux. The materials and geometry are optimized to
provide a low resistance inductor for use in high performance integrated
circuits. In another embodiment the inductor is arranged on an integrated
circuit package substrate. Also described are methods of fabricating the
inductor on an integrated circuit or as part of an integrated circuit
package.
