Methods of producing a solid state air core spiral inductor are presented. A spiral coil can be deposited on a substrate. One or more solder dams can be positioned on the coil where the dams comprise a well into which solder bumps can be attached to the coil. Material covering the coil or between the gaps the inductor's coil can be removed yielding an air core. Contemplated inductors can include one or more tap points.
