Abstract

Within both a micro fabrication and a method for fabricating the micro fabrication there is formed over a substrate a spirally patterned conductor layer spirally topographically tapered in a vortex shape. The spirally patterned conductor layer is particularly useful as a microelectronic inductor structure within a microelectronic fabrication.
