Using novel micromachining technology, various three-dimensional (3D) on-chip inductors have been fabricated to achieve high performance and small area occupation for GHz applications. We have obtained 14nH, a peak Q of 38 at 1.8GHz with area occupation of 500μm by 500μm excluding pads (56nH/mm2) from a stacked spiral inductor on a glass substrate. Also, 1.75nH and a peak Q of 57 at 10GHz have been obtained from a levitated spiral inductor.
